Activity 1: Network DesignActivity 2: Building Peer to Peer Network (Window XP and Win 2003)




TOPIC A: PLANNING A NETWORK

Before you begin any networking project, whether it’s a new network installation or an upgrade of an existing network, you should first make a detailed plan. If you make technical decisions too quickly, before studying all the issues that affect the project, you’ll regret it. You’ll discover too late that a key application won’t run over the network, that the network has unacceptablyslow performance, or that key components of the network don’t work together.

Here are some general thoughts to keep in mind while you create your network plan:

Don’t rush the plan Write down the network plan Ask someone else to read your network plan before you buy anything. Keep the plan up to date.

STEPS IN PLANNING A NETWORK

1. Purpose of the networkOne of the first steps in planning your network is making sure that you understand why you want the network. Make sure that you identify all the reasons why you think you need a network and then write them down.

2. Taking the stockOne of the most challenging parts of planning a network is figuring out

how to work with the computers that you already have. In other words, you have to take a thorough inventory of your current computers.

3. Type of ServerOne of the most basic questions that a network plan must answer is whether the network will have one or more dedicated servers or rely completely on peer-to-peer networking.

a. File Servers




b. Print Serversc. Mail Serversd. Database Servers

4. Choosing a NOSIf you determine that your network will require one or more dedicated

servers, the next step is to determine what network operating system those servers should use. If possible, all the servers should use the same NOS so that you don’t find yourself supporting different operating systems.

Although you can choose from many network operating systems, from a practical point of view, your choices are limited to the following:

Windows Server 2003 or 2008 Linux or another version of Unix

5. Planning the InfrastructurePlan the details of how you will connect the computers in the network. This includes determining which network topology that the network will use, what type of cable will be used, where the cable will be routed, and what other devices, such as repeaters, bridges, hubs, switches, and routers, will be needed.

6. Drawing DiagramsOne of the most helpful techniques for creating a network plan is to draw a picture of it. The diagram can be a detailed floor plan, showing the actual location of each network component. This type of diagram is sometimes called a physical map.




TOPIC B: SELECTING A NETWORK CONNECTION

The biggest decision you need to make when creating your network is what type of connection you will use. Gateway supports both wired and wireless Ethernet networks. Use the following criteria as a guide when selecting a network connection.

Wired Ethernet network

A wired Ethernet network consists of two or more computers connected together through an Ethernet cable. This connection type is commonly used in offices around the world and can be used to build computer networks in the home.

Create a wired Ethernet network if:

You are building a new home or your existing home already has Ethernet cable installed in each room that has a device you want to connect

You are creating a network in an office or business where network speed is more important than moving about with your computer

Your computer has an Ethernet jack for connecting to the network

Example wired Ethernet network




Wireless Ethernet network

A wireless Ethernet network is ideal for creating a home or office network or adding mobility to an existing wired Ethernet network. A wireless Ethernet network allows you the freedom to move about your home or office with your notebook or tablet PC.

Create a wireless Ethernet (IEEE 802.11a, IEEE 802.11b, IEEE 802.11g or 802.11n) network if:

You are looking for an alternative to installing cable for connectivity The ability to move about with your computer is as important as network speed Your computer has wireless Ethernet for networking




TOPIC C: NETWORK MODEL

1. Workgroup ModelMicrosoft’s workgroup model for networking distributes resources, administration, and security throughout a network. Each computer in a workgroup can be a server, a client, or both.

Advantage DisadvantageEasy-to-share resources No centralized control of resourcesResources are distributed across all machines

No centralized account management

Little administrative overhead No centralized administration Simple to design No centralized security managementEasy to implement Inefficient for more than 20 workstationsConvenient for small groups in close proximity

Security must be configured manually

Less expensive, does not require a central server

Increased training to operate as both client and server

2. Domain Model By dedicating one or more servers to the job of controlling a domain, the domain model adds a layer of complexity to networking. But the domain model also centralizes all shared resources and creates a single point of administrative and security control.

Advantage Disadvantage




Centralized resource sharing Significant administrative effort and overhead

Centralized resource controls Complicated designs; requires advanced planning

Centralized account management Requires one or more powerful, expensive servers.

Centralized security management Support personnel need to be trained in security management.

Efficient for virtually unlimited number of workstations

Expense for domain controllers and access lags increase with network size

Users need to be trained only to use clients

Support personnel need to be trained in domain network management.

Not restricted to close proximity Larger scope requires more user documentation and training.

TOPIC D: STRUCTURED CABLING

Structured cabling specification T568 makes recommendations for the following basic elements of networks:

Building Entrance Requirements - Specifications for the point at which outside cabling enters a building.

Equipment Room - Storage area for the more expensive, complex equipment, often the existing telecommunications closets.

Backbone Cabling - Cabling (often referred to as vertical) that carries the signals from equipment room to equipment room, between floors, and to and from the building entrance connections.

Horizontal Cabling- ransmission media that carries signals from a same floor equipment room to the various work areas.

Work Area - Any area where the computer workstations, printers, etc. are located, typically office space.

Backbone Cabling Connects Equipment Rooms




The wiring used for backbone cabling may be either copper or fiber optic.Recommended backbone cable maximum distance limitations include:

Voice grade 100 ohm UTP 800 meter limitation STP data grade 150 ohm 90 meter limitation Multimode 62.5/125μm fiber 2,000 meter limitation Patch cable 3 - 6 meter limitation

Horizontal Cabling




Most often, horizontal cable is routed directly from the wiring closet to the workstation, without splices, cable junctures, or taps. By eliminating splices, cable junctures and/or taps, the potential for faulty connections and electrical noise is reduced. Although not necessary, it is recommended that horizontal cabling be rated for category 5 use.

Maximum transmission speeds for horizontal cable are: Category 3 up to 16 MHz Category 4 up to 20 MHz Category 5 up to 100 MHz

Maximum recommended distance limitation for horizontal cable:

100 meters total Maximum of 3 meters from wall jack to workstation Maximum of 6 meters in the telecommunications closet Maximum of 90 meters from telecommunications closet to wall jack




The wall jack outlet must have a minimum of two ports, one for voice grade transmissions and one for data grade transmissions. Recommended horizontal cabling includes:

4-pair 100 ohm UTP 2-pair 150 ohm STP 2 fiber 62.5/125μm optical

NETWORK TOPOLOGY

1. Bus Topology - When computers were first networked together, they were simplyconnected to one cable segment in a series.

2. Ring Topology – devices connected in a closed loop and have equal access.

3. Star Topology – Star topology is a point-to-point architectural design where all computer devices are connected to a central hub, through which all data signals must travel.




4. Hybrid Network Topology - Hybrid topology is any combination of bus, star, and ring topology, for example, a star-bus configuration.

5. Mesh Topology - Every device is connected to every other device. Used in WANs to interconnect LANs

6. Wireless Topology few cables are used to connect systems made up of transmitters that broadcast the packets using radio frequencies contains special transmitters called cells or wireless access point

ACTIVITY 1: NETWORK DESIGN12 Prepared by: MTGuillermo



Materials Needed

Spreadsheet application Drawing application Cable cost analysis prepared

Work with a partner to create a list of questions you should ask a client who has hired you to build a network. The client wants to know which type of cable you plan to use and why, how much the cable will cost, and why you selected the particular topology. The client also wants you to submit a proposal that defends your choice of cabling and network design.

After you create your questionnaire, role-play with your partner. One of you will assume the role of client, and the other the role of the network designer. The client will answer all the questions for a fictitious company of his/her choice. The network designer will record all of the answers.

When the questionnaire is complete, you will both analyze the requirements and determine the appropriate topology. Create a computer diagram of the proposed network for the client. Prepare a spreadsheet that shows a cost analysis of the cable needed to complete the job. The cost analysis should include the type of cable, length of cable, cost of each type of cable, and the total cable cost. Use the cost information you gathered in the cabling lesson.

Submit a proposal to the client indicating the suggested network topology. Include a summary to convince the client that this is the best, most cost efficient design for her/his needs. Your proposal must also defend your cable choices. Attach the computer diagram and cable cost analysis spreadsheet to your proposal.

Evaluation Criteria and Weightings

Name: ________________________________________________ Section: _______________




Activity 1Building a Peer-to-Peer Network (XP meets 2003)

Objectives

Design and build a simple peer-to-peer network using a crossover cable supplied by the instructor.Verify connectivity between the peers using the ping command.File and Printer Sharing

Background / Preparation

In this hands-on lab, you will plan and build a simple peer-to-peer network using two PCs and an Ethernet crossover cable.

The following resources are required:

Two Window XP Professional PCs, each with an installed and functional Network Interface Card (NIC)An Ethernet crossover cable

Step 1: Diagram the network

a. A network diagram is a map of the logical topology of the network. In the space below, sketch a simple peer-to-peer network connecting two PCs. Label one PC with IP address 192.168.1.1 and the other PC with IP address 192.168.1.2. Use labels to indicate connecting media and any necessary network devices.




b. A simple network like the one you designed can use a hub or switch as a central connecting device, or the PCs may be directly connected. Which kind of cable is required for a direct Ethernet connection between the two PCs?

____________________________________________________________________________

Step 2: Document the PCs

a. Check the computer name settings for each PC and make adjustments as necessary. For each PC, select Start and Control Panel. Double-click the System icon, then click the Computer Name tab. Write down the computer name that is displayed following Full computer name:

b. Check to see if the two PCs have the same name. If they do, change the name of one PC by clicking the Change button, typing a new name in the Computer name field, then clicking OK.

c. Click OK to close the System Properties window.

d. Why is it important that each PC on a network have a unique name?




Step 3: Connect the Ethernet cable

a. Use the Ethernet crossover cable provided by the instructor. Plug one end of the cable into theEthernet NIC of PC1.

b. Plug the other end of the cable into the Ethernet NIC of PC2. As you insert the cable, you should hear a click which indicates that the cable connector is properly inserted into the port.

Step 4: Verify physical connectivity

a. After the Ethernet crossover cable is connected to both PCs, take a close look at each Ethernet port. A light (usually green or amber) indicates that physical connectivity has been established between the two NICs. Try unplugging the cable from one PC then reconnecting it to verify that the light goes off then back on.

b. Go to the Control Panel, double click the Network Connections icon, and confirm that the local area connection is established. The following figure shows an active local area connection. If physical connectivity problems exist, you will see a red X over the Local Area Connection icon with the words Network cable unplugged.




c. If the Local Area Connection does not indicate that it is connected, troubleshoot by repeating Steps 3 and 4. You may also want to ask your instructor to confirm that you are using an Ethernet crossover cable.

Step 5: Configure IP settings

a. Configure the logical addresses for the two PCs so that they are able to communicate using TCP/IP. On one of the PCs, go to the Control Panel, double click the Network Connections icon,

b. and then right click the connected Local Area Connection icon. Choose Properties from the pull-down menu.

b. Using the scroll bar in the Local Area Connection Properties window, scroll down to highlight Internet Protocol (TCP/IP). Click the Properties button.

c. Select the Use the following IP address radio button and enter the following information:




d. Click OK, which will close the Internet Protocol (TCP/IP) Properties window. Click the Close button to exit the Local Area Connection Properties window.

e. Repeat steps 5a – 5d for the second PC using the following information

Step 6: Verify IP connectivity between the two PCs

NOTE: To test TCP/IP connectivity between the PCs, Windows Firewall must be disabled temporarily on both PCs. Windows Firewall should be re-enabled after the tests have been completed.

a. On PC1, on the Windows XP desktop, click Start. From the Start menu, select Control Panel, and double-click Network Connections.

b. Right-click the Local Area Connection icon and select Properties. Click the Advanced tab. Locate and click the Settings button.:




c. Make a note of whether the firewall settings are ENABLED (ON) for the Ethernet port or DISABLED (OFF) for the Ethernet port. ___________________________________________________________________________

d. If the firewall settings are enabled, click the Off (not recommended) radio button to disable the firewall. The setting will be re-enabled in a later step. Click OK in this dialog box and the following to apply this setting.

e. Now that the two PCs are physically connected and configured correctly with IP addresses, we need to make sure they communicate with each other. The ping command is a simple way to accomplish this task. The ping command is included with the Windows XP operating system.f. On PC1, go to Start, then Run. Type cmd, and then click OK. A Windows command prompt window will appear as shown in the figure below.

g. At the > prompt, type ping 192.168.1.2 and press Enter. A successful ping will verify the IP connectivity. It should produce results similar to those shown in here.

h. Repeat Steps 6a-6c on the second PC. The second PC will ping 192.168.1.1.

i. Close the Windows command prompt window on both PCs.Step 7: Verify connectivity using My Network Placesa. A PC can share its resources with other PCs on the network. PCs with shared resources should be visible through My Network Places. On PC1, go to Start, click My Network Places, and then click View workgroup computers in the left pane




b. Do you see an icon for the other PC in your peer-to-peer network? ______________________

c. What is the name of the other PC? ________________________________________________

d. Is it the same name you recorded in Step 2? ________________________________________

e. Perform Step 7a on the second PC.

f. Close any open windows.

Step 8: (Optional – Use only if the Firewall was originally ENABLED) Re-enable the firewall

a. If you disabled the Windows Firewall in Step 6, click Start, select Control Panel, and open the Network Connections control panel.

b. Right-click the Ethernet network connection icon and select Properties. Click the Advanced tab. Locate and click Settings.

c. If the firewall settings are disabled (and they were enabled before this lab began), click the On radio button to enable the firewall. Click OK in this dialog box and the following one to apply this setting.

Step 9: File and Printer Sharing

a. In PC 1 connect the printer. Create a text document in notepad file name: Your Surname and save in folder name Test




b. Share the printer and the folder Test

c. Using PC 2 copy the shared document in PC 1 (notepad) then print.

TYPES OF GROUPS

1. Local groups - exist only on a single computer

2. Global groups - exist in the domain

DEFAULT GROUPS

GROUP DESCRIPTIONAdministrators Computer administrators have complete control

over the computerPower Users Power Users can perform most actions that administrators can

perform, but they can only modify and delete accounts that they create. Also, they can only modify group memberships that theyhave created.

Users This is the default limited user account. Users can configure the desktop systems and create files, but they cannot make any configuration changes to the system, add or remove accounts, or access other users’ folders.

Backup Operators Backup Operators can back up and restore files on the computer, regardless of which user owns those files. Backup operators cannot be changed.

Guests This enables a guest to log on to the computer. Guests can perform basic computing actions, but do not have all of the abilities given to the limited user accounts.

Network Configuration Operators

This provides some basic administrative privileges for the configuration of Windows XP’s networking features. Typically, under local usage, the administrator would handle these functions.

Remote Desktop Users If Remote Desktop is configured, this group is provided for remote desktop users to access theremote access connection.




Replicator Use by special user accounts to facilitate directory replication between system and domain. It has no default members

Help Services Group This is provided for the Help and Support Center.

SYSTEM GROUPS

System groups are preexisting groups that you can’t manage but that appear in dialog boxes when assigned group membership or access permissions. These are groups are used by the system to control or place restrictions on specific groups of users based on their activities.

Activity 3: IPv6 Address Notation Exercise Activity 4: Enable IPv6 in Window XP

TOPIC A: TCP/IP FEATURES

Transmission Control Protocol/Internet Protocol (TCP/IP)

The basic language or protocol used for the Internet.

A suite of networking protocols, including both IPv4 and IPv6, that are widely used on the Internet and that provide communication across interconnected networks of computers with diverse hardware architectures and various operating systems.

Features of TCP/IP protocols:

TCP/IP is independently developed from any specific hardware or operating systems




It is open protocol standards and freely available It is widely used for the Internet, Intranet and Extranet Most of the products manufactured by vendors have support for TCP/IP TCP/IP allows integration of different kind of networks It can run over an Ethernet, token ring, dial-up line or any other kinds of physical

transmission media TCP/IP has a common addressing scheme that allow device to uniquely address on

the entire network, even if the network is as large as the worldwide Internet TCP/IP standardized high-level protocols for consistent, widely available user services

TCP/IP Components in Windows

Advantages of the TCP/IP protocol suiteAdvantages of TCP/IP components in Windows

A standard, routable enterprise networking protocol that is the most complete and accepted protocol available. All modern operating systems support TCP/IP, and most large private networks rely on TCP/IP for much of their traffic.

TCP/IP components in Windows enable enterprise networking and connectivity for Windows and non-Windows–based computers.




A technology for connecting dissimilar systems. Many TCP/IP application protocols were designed to access and transfer data between dissimilar systems. These protocols include HTTP, FTP, and Telnet.

TCP/IP components in Windows allow standards-based connectivity to other operating system platforms.

A robust, scaleable, cross-platform client/server framework.

TCP/IP components in Windows support the Windows Sockets application programming interface, which developers use to create client/server applications.

A method of gaining access to the Internet. Windows-based computers are Internet-ready.

TOPIC B: UNDERSTANDING IP ADDRESS

IP ADDRESS

A unique identifier for a node or host connection on an IP network A 32 bit binary number usually represented as 4 decimal values consist of 4

octet




Example : 140.179.220.200

Convert to binary

140 179 220 20010001100 10110011 11011100 110010001st octet 2nd octet 3rd octet 4th octet

TWO TYPES OF IP ADDRESS

1. IPv4 – Ex. 192.168.1.2

2. IPv6 - 128 bits long and are represented by 16-bit hexadecimal segments

Ex. 2001:0D02:0000:0000:0000:C003:0001:F00D

Subnet Mask

Applying subnet mask allows to identify the network and host part of the IP address.

Looking at a subnet mask, if there is a 255 in an octet, then the corresponding octet in the IP address is part of the network ID. For example, if I had an IP address of 192.168.1.15 and a subnet mask of 255.255.255.0, the fi rst three octets would make up the network ID and the last octet would be the host ID. The network ID assigns a unique address to the network itself, while the host ID uniquely identifies the system on the network.

Address Classes

Every IP address belongs to a distinct address class. The Internet community defi ned these classes to accommodate networks of various sizes. The class to which the IP address belongs initially determines the network ID and host ID portions of the address,




along with the number of hosts that are supported on that network. The different class addresses are named Class A, Class B, Class C, Class D, and Class E.

Class A Addresses

IP address in which the first octet is between 1 and 126.

IP address that starts with 127 is a class A address as well, but you are not allowed to use any address that starts with 127 because it is reserved for the loopback address

Loopback Address

A range of 127 has been reserved for the loopback address. The loopback address is used to refer to the local system, also known as the local host. If you want to verify that the TCP/IP software has initialized on the local system even though you may not have an IP address, you may PING the loopback address, which is typically referred to as 127.0.0.1.

You can test your own local system by typing ping 127.0.0.1, ping local host, or ping loopback, to verify that the TCP/IP protocol stack is functioning on your system.

Class D Addresses

Class D addresses are used for special types of applications on the network known as multicasting applications. Multicasting applications send data to a number of systems at the same time by sending data to the multicast address, and anyone who has registered with that address will receive the data. A multicast address is what class D addresses are used for, so you will not be assigning them specifically to hosts on the network for normal network communication. Class D addresses have a value on the first octet that ranges from 224 to 239.

Class E AddressesClass E addresses is that were designed for experimental purposes only, so you will not ever see a class E address on a network. Class E addresses have a first octet with a value that falls in the range of 240 to 254.

Private Addresses

Another type of address you need to be aware of is what is known as a private address. A private address is an address that can be assigned to a system but cannot be used for any kind of Internet connectivity. The private addresses are nonroutable addresses, so any system using them will not be able to function off the network. The following are the three address ranges that are the private address ranges:

■ 10.0.0.0 to 10.255.255.255■ 172.16.0.0 to 172.31.255.255■ 192.168.0.0 to 192.168.255.255

Not being able to route data across the Internet when using these addresses will not pose a problem, because realistically, you will have these private addresses sitting behind a network address translation (NAT) server that will translate the private address to a public address that can be routed on the Internet

TOPIC C: IPv4 CUSTOM SUBNETTING




SUBNETTING

The purpose of subnetting is to break one network ID into multiple subnetworks (subnets) so that you can follow the physical structure of the network.

With subnetting you take host bits from the subnet mask and mask them to be network bits—thus creating more networks but fewer machines per network.

To determine how many bits to take from the host ID portion of the subnet mask.

STEPS IN SUBNETTING

1. Determine the number of networks and convert in to binary.

2. Reserve bits in subnet mask and find your increment

3. Use your increment to find your network ranges

SUBNETTING BASE ON NETWORKS

Given:

IP Address = 216.21.5.0 Default subnet mask = 255.255.255.0 Subnet = 5

1. Determine the number of networks and convert to binary.

Subnet = 5 convert to binary

5 = 101 = 3 bits

2. Reserve bits in subnet mask and find your increment

Subnet 4 216.21.5.96 to 216.21.5.127

Subnet 5 216.21.5.128 to 216.21.5.159

Invalid IP Address is the first and last IP address of each subnet

Formula to determine the number of networks

Number of networks = 2n

Where n is equal to number of 1’s in the subnet mask

255 255 255 22411111111 11111111 11111111 11100000

Number of networks = 227

= 134,217,728

Formula to determine the number of host

Number of Host = 2n – 2

Where n is equal to the number of O’s in the subnet mask

Number of Host = 25 – 2

= 30

Subtract 2 because the 1st and last IP address is not valid it is used as Nework ID and Broadcast Address

TOPIC D: INTERNET PROTOCOL VERSION 6

IPv6 (Internet Protocol Version 6)

IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4 The key to IPv6 enhancement is the expansion of the IP address space from 32 bits to

128 bits, enabling virtually unlimited unique IP addresses It is recommended by the Internet Engineering Task Force on July 25, 1994 (Toronto

IETF meeting) The IPv6 has auto configuration feature, automatically configures interface and Brouter

addresses for you IPv6 protocol can coexist with current IPv4 protocol

The IPv6 Address Space




IPv6 Conversion

Hexidecimal to Binary Conversion

Pv6 FeaturesThe following are the features of the IPv6 protocol:

New header format

Large address space

Efficient and hierarchical addressing and routing infrastructure

Stateless and stateful address configuration

Built-in security

Better support for prioritized delivery

New protocol for neighboring node interaction

Extensibility

IPv6 Implementations from MicrosoftMicrosoft® has the following implementations of IPv6:

The Next Generation TCP/IP stack in Windows Vista™ and Windows Server® 2008.

The IPv6 protocol for the Windows Server 2003 family.

The IPv6 protocol for Windows® XP Service Pack 1 (SP1) and later.

The IPv6 protocol for Windows CE .NET version 4.1 and later.

The capture and parsing of IPv6 traffic is supported by Microsoft Network Monitor.




For all the IPv6 implementations from Microsoft, you can use IPv6 without affecting IPv4 communications.

IPv6 address notation

There are three possible notation types that can be used to represent IPv6 addresses. The notation you use depends on the content of the address you want to represent.

1. Standard notation The standard notation for IPv6 addresses is to represent the address as eight 16-bit hexadecimal words separated by ``:'' (colons). For example:

FEDC:BA98:0332:0000:CF8A:000C:2154:7313

NOTE: It is not necessary to specify leading zeros, as long as there is at least one numeric value in each field of the address. The above address could also be represented as FEDC:BA98:332:0:CF8A:C:2154:7313.

2. Compressed notation Since a large number of IPv6 addresses contain multiple fields of zeros, there is a notation you can use to represent a single contiguous group of zero fields within an IPv6 address. This notation is a double colon ``::''. Some examples of how to use the ``::'' are shown below.

1762:0:0:0:0:B03:1:AF18 FF01:0:0:0:CA:0:0:2 0:0:0:0:0:0:0:1 0:0:0:0:0:0:0:0

can be represented as:

1762::B03:1:AF18 FF01::CA:0:0:2 ::1 ::

NOTE: The FF01:0:0:0:CA:0:0:2 example is represented as FF01::CA:0:0:2 because only one ``::'' is allowed in an address.




3. Mixed notation IPv4 addresses that are encapsulated in IPv6 addresses can be represented using the original IPv4 ``.'' notation as follows:

0:0:0:0:0:0:127.32.67.15 0:0:0:0:0:FFFF:127.32.67.15

It is also possible to use the compressed notation, so the addresses above would be represented as: ::127.32.67.15 ::FFFF:127.32.67.15

IPv6 PrefixesThe prefix is the part of the address that indicates the bits that have fixed values or are the bits of the subnet prefix. Prefixes for IPv6 subnets, routes, and address ranges are expressed in the same way as Classless Inter-Domain Routing (CIDR) notation for IPv4. An IPv6 prefix is written in

address/prefix-length notation. For example, 21DA:D3::/48 and 21DA:D3:0:2F3B::/64 are IPv6 address prefixes.

IPv6 Subnet Masking

What Gets Masked (Which Bits?)Like IPv4, an IPv6 address has a network portion and a device portion. Unlike IPv4, an IPv6 address has a dedicated subnetting portion. Here's how the ranges are divided in IPv6:

Network Address RangeIn IPv6, the first 48 bits are for Internet routing.1111111111111111.1111111111111111.1111111111111111.0000000000000000.0000000000000000.0000000000000000.0000000000000000.0000000000000000

Subnetting RangeThe 16 bits from the 49th to the 54th are for defining subnets.0000000000000000.0000000000000000.0000000000000000.1111111111111111.0000000000000000.0000000000000000.0000000000000000.0000000000000000

Device (Interface) Range:The last 64 bits are for device (interface) ID's.




0000000000000000.0000000000000000.0000000000000000.0000000000000000.1111111111111111.1111111111111111.1111111111111111.1111111111111111

Let's say you want to break your corporate network into 64 subnets. The binary mask just for the subnetting range would be1111110000000000 which translates to a hex value of FC00. Some IPv6 masking tools will work with just this one hex word, otherwise a full 128-bit hex mask would be FFFF:FFFF:FFFF:FC00:0:0:0:0.

Types of IPv6 Addresses

1. Unicast - communicate specified 1 computer

2. Multicast - communicate group of computers

3. Anycast send group address that can receive multiple computers,but receive 1 computer

Unicast IPv6 AddressesThe following types of addresses are unicast IPv6 addresses:

Global unicast addresses

Global unicast addresses are equivalent to public IPv4 addresses. They are globally routable and reachable on the IPv6 portion of the Internet.

Link-local addresses

Link-local addresses are used by nodes when communicating with neighboring nodes on the same link. For example, on a single link IPv6 network with no router, link-local addresses are used to communicate between hosts on the link.

Site-local addresses

Site-local addresses are equivalent to the IPv4 private address space (10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16).

Unique local IPv6 unicast addresses

Special addresses




Special IPv6 AddressesThe following are special IPv6 addresses:

Unspecified address

The unspecified address (0:0:0:0:0:0:0:0 or ::) is only used to indicate the absence of an address.

Loopback address

The loopback address (0:0:0:0:0:0:0:1 or ::1) is used to identify a loopback interface, enabling a node to send packets to itself.

Compatibility AddressesTo aid in the migration from IPv4 to IPv6 and the coexistence of both types of hosts, the following addresses are defined:

IPv4-compatible address

The IPv4-compatible address, 0:0:0:0:0:0:w.x.y.z or ::w.x.y.z (where w.x.y.z is the dotted decimal representation of an IPv4 address), is used by IPv6/IPv4 nodes that are communicating using IPv6.

IPv4-mapped addressThe IPv4-mapped address, 0:0:0:0:0:FFFF:w.x.y.z or ::FFFF:w.x.y.z, is used to represent an IPv4-only node to an IPv6 node. It is used only for internal representation.

6 to 4 address

The 6to4 address is used for communicating between two nodes running both IPv4 and IPv6 over an IPv4 routing infrastructure. The 6to4 address is formed by combining the prefix 2002::/16 with the 32 bits of a public IPv4 address, forming a 48-bit prefix. 6to4 is a tunneling technique described in RFC 3056.

Activity 2: Setting up NetMeetingActivity 3: Internet Café Software InstallationActivity 4: Building a Network using 4 switch (Use Packet Tracer)

TOPIC A: TYPES OF WORKGROUPS

Workgroup

A group of computers that are connected on a network and share resources, such as printers and files. When you set up a network, Windows automatically creates a




workgroup and gives it a name.

TYPES OF WORKGROUP

1. Direct Cable ConnectionA Direct Cable Connection (DCC) is not really a workgroup configuration in the true sense of the word, but it does bear mentioning here because it is a quick and easy method to connect two computers together.

Using a DCC, you can establish a connection between a Windows XP computer and any other Microsoft Windows computer that supports DCC connections.

2. EthernetEthernet is a networking standard and the most popular kind of network in usetoday. When you think of a network with a typical wired configuration, you aregenerally thinking of Ethernet.

3. HomePNAHomePNA is another type of network topology that is designed for home use, but itworks well in small offices too. HomePNA networks use typical PCI or USB NICs,but each NIC connects to a standard phone jack in the home or small office using astandard RJ-11 phone cable. Rather than using a hub and having wiring runningeverywhere, you simply use existing phone lines as the network.

4. Wireless Networks

Major Type of Wireless Network

1. Infrared—Infrared wireless uses an infrared beam to transmit data from one device to the next, and is most often used in PC devices.

2. Wireless Personal Area Networks (WPANs)—A WPAN is a personal areanetwork, meaning it resides in one generalized space, such as a room.

3. Wireless Local Area Networks (WLANs)—A WLAN is a wireless network that exists within one geographic location, such as in a home, office building, school, or other such structure.




4. Wireless Metropolitan Area Networks (WMANs)—WMANs allow communicationbetween different locations within a single metropolitan area.

5. Wireless Wide Area Networks (WWANs)—A WWAN connects WLANs that are separated over wide geographic areas.
