What is Driving IPv6?Depletion of IPv4
What is Driving IPv6?
Adoption of DirectAccess by Microsoft Enterprises
Audit and security compliance due to IPv6 being enabled by default since Windows Vista and Server 2008
Ability to provide effectively unlimited number of IP addresses for large business divisions
The rapid growth of cloud services requiring elastic compute resources and flexible addressing
What is IPv6 and how do I get started?
IPv6 is the next generation Internet networking protocol
Much larger than IPv4 which uses 32 bits or 232 or 4,294,967,296
IPv6 is 128 bits or 2128 or 340 undecillion addresses 340,282,366,920,938,463,463,374,607,431,768,211,456
IPv6 is enabled by default in Windows
You have likely already deployed IPv6You just didn’t know it - oops
What does an IPv6 address look like?
2001:0470:82a9:0007:f2de:f1ff:fe5b:b324
Or
2001:470:82A9:7::1/64
Or
fe80::f2de:f1ff:fe5b:b324%13
2001:470:1f05:d37:202c:7674:c4c2:4fa8
Each : divides the address along 16-bit boundaries
And the address is represented in HEX
4-bits is called a nibble
IPv6 address types
UnicastIdentifies a single interface and is used for host to host communication
MulticastIdentifies zero or more interfaces on one or more hostsMulticast are group addresses used for one to many hosts or many to many hosts
AnycastIdentifies multiple interfaces on one or more hostsAnycast are special purpose unicast addresses
Unicast IPv6 Addresses
Unicast typesGlobal unicast addresses (2000::/3 – RFC 4291 & RFC 3587)Link-local addresses (FE80::/64 – RFC 4007)Unique local addresses or ULA (FC00::/7 – RFC 4193)Special addresses (unspecified is :: & loopback is ::1 – RFC 5156)Transition addresses (6to4, ISATAP, Teredo)
Unicast types that have been deprecatedSite-local addresses (see RFC 3879)IPv4-compatible addresses (see RFC 4291)
Most common IPv6 addresses you will see are Global and Link-
local
Multicast IPv6 Addresses
Multicast addresses have the first 8 bits set to 1So multicast addresses start with FF (FF00::/8)Multicast also has a 4 bit flag field and 4 bit scope fieldSolicited-node address (FF02::1:FF00:0/104)
Some example multicast addressesFF01::1 – interface-local scope all-nodesFF02::1 – link-local all-nodesFF01::2 – interface-local scope all-routersFF02::2 – link-local add-routersFF05::2 – site-local scope all routers
Anycast IPv6 Addresses
Anycast addresses are assigned out of the unicast space
Anycast addresses are destination onlyThe address is advertised by a local routerThe address can be redistributed by routersMultiple routing paths to the same address are possible
You can’t tell it is an Anycast address by
looking at it
“IPv6 Addresses” are unicast and global
“Temporary IPv6 Addresses” are unicast and global
“Link-local IPv6 Address” is unicast and local
Link-local will have a Zone ID (also called
Scope ID) represented by the
%<ID> after the IPv6 Address
IPv6 Interface ID
Last 64 bits of a unicast addressInterface ID is fixed length (host portion of the IPv6 address)
Interface ID optionsEUI-64 (RFC 4291) – stateless autoconfigurationTemporary Address (RFC 4941) – stateless autoconfigurationStateful autoconfiguration (DHCPv6)Manual (statically assigned)Permanent (randomly generated)
Organizational Unique Identifier
Factory Assigned 48 bit MAC Address
xxxxxx00 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxxx
xxxxxxxx xxxxxxxx xxxxxxxxxxxxxxx00 xxxxxxxx xxxxxxxx
1111111011111111
0xFF 0xFE
xxxxxx10 xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxx xxxxxxxxx1111111011111111
Flip this Bit
Standard EUI-64
Modified EUI-64 – flip the universal/local bit
EUI-64 – How it is Built
2001:470:82a9:7:f2de:f1ff:fe5b:b324
MAC address: F0-DE-F1-5B-B3-24
Take MAC and split it, stuff in FF:FE and flip the 7th bit
Look for the FF:FE in the address, then it is
likely EUI-64
IPv6 Prefix
A network prefix such as 2001:db8::/64Is saying the following :
2001:0db8:0000:0000:0000:0000:0000:0000/64| network portion | host portion |
| provider assigned | locally assigned |
A different network prefix example 2001:db8::/48
2001:0db8:0000:0000:0000:0000:0000:0000/48| Network Prefix |subnet| host |
| 48 bits |16 bits | 64 bits |
Indicates the number of bits that define the network
IPv6 Subnetting
An example network prefix of 2001:db8:cafe::/48:2001:0db8:cafe:0000:0000:0000:0000:0000/48| Network |subnet| host |
| 48 bits |16 bits | 64 bits |
When subnetting use natural nibble boundaries (count in increments of 4 when selecting subnets, i.e. /60 /56 /52)
/48 = 65,536 networks of /64/52 = 4,096 networks of /64 and 16 subnets/56 = 256 networks of /64 and 256 subnets/60 = 16 networks of /64 and 4,096 subnets
IPv6 Subnetting Guidelines
An example network prefix of 2001:0db8:cafe::/48:2001:0db8:cafe:0000:0000:0000:0000:0000/48| Prefix |subnet| host |
| 48 bits |16 bits | 64 bits |
An example of subnetting 2001:0db8:cafe::/48 into /60’s:
2001:0db8:cafe:0000:0000:0000:0000:0000/60| 48 bits |12| 0 | do not use |
| 60 bits | 0 | do not use |
Therefore a /48 has 4,096 subnets of /60 networks260 – 248 = 212 = 4,096
IPv6 Subnetting Math
An example of subnetting 2001:db8:cafe:cab::/60 into /64’s :
2001:0db8:cafe:cab0:0000:0000:0000:0000/60| 60 bits | | 64 bits |
A /60 has 16 /64 subnets264-260 = 24 = 16
The /60 value ranges in HEX would be:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F
IPv6 Subnetting Math – non-nibble horror
An example of subnetting 2001:db8:cafe:cab::/60 into /62’s :
2001:0db8:cafe:cab0:0000:0000:0000:0000/60| 60 bits | | 64 bits |
A /62 has 4 /64 subnets264-262 = 22 = 4
The /62 value ranges in HEX would be:0, 1, 2, 3 4, 5, 6, 78, 9, A, B C, D, E, F
IPv6 Subnetting Math – non-nibble horror
So subnetting 2001:db8:cafe:cab::/60 into /62’s ranges :
2001:0db8:cafe:cab< 0 - 3 >:0000:0000:0000:0000/62| 60 bits |range| 64 bits |
2001:0db8:cafe:cab< 4 - 7 >:0000:0000:0000:0000/62| 60 bits |range| 64 bits |
2001:0db8:cafe:cab< 8 - B >:0000:0000:0000:0000/62| 60 bits |range| 64 bits |
2001:0db8:cafe:cab< B - F >:0000:0000:0000:0000/62| 60 bits |range| 64 bits |
IPv6 Subnetting Best Practices
Stick to increments of 4!
Count by 4!!!
Have you noticed anything odd yet?
Why is it always
/64?
Stateless Address Autoconfiguration (SLAAC)
IPv6 hosts have the ability to self provision an IPv6 address
A host uses router discovery to:Router Solicitation messagesRouter Advertisement messages (RA’s are sent via ICMPv6)Get information like on-link prefixes and other routers
SLAAC requires the prefix be a /64If the prefix is smaller the host cannot do EUI-64This breaks the ability of the host to do SLAAC
SLAAC Only
2001:470:82a9:7::/64 is the prefix
Notice there are no global DNS Servers
Notice there is no FQDN information
This typically indicates SLAAC – the host lacks DNS server
info
Also indicates poorly implemented IPv6
IPv6 Autoconfiguration
There are multiple ways to do autoconfiguration
Stateless (SLAAC)Stateful (DHCPv6 stateful)Both (DHCPv6 stateless)
Router Advertisements include flagsAutonomous flag (A flag)Managed Address Configuration flag (M flag)Other Stateful Configuration flag (O flag)
DHCPv6 – RFC 3315
DHCPv6 is stateful and stateless address configuration for IPv6 hosts
What is Stateful?The DHCPv6 server is assigning the IPv6 addressThe RA has the M and O flag set (A flag may or may not be set)All options except default gateway come from DHCPv6 scope
What is Stateless?The DHCPv6 server is used for options only (like DNS or NTP)The RA has the O flag set and the A flag
DHCPv6 – RFC 3315
The typical flag settings combination:SLAAC: A flag = 1, M flag = 0, O flag = 0DHCPv6 Stateful: A flag = 0, M flag = 1, O flag = 1DHCPv6 Stateless: A flag = 1, M flag = 0, O flag = 1
For all situations a host link-local address is configured automatically (exception may be routers)
DHCPv6 w/ A, O and M Flags
2001:470:82a9:7:41a6:5976:37ac:4f54 is from DHCPv6
2001:470:82a9:7:202c:7674:c4c2:4fa8 is from SLAAC
2001:470:82a9:7:3d1f:ad49:ee12:4880 is from SLAAC
Windows specific Autoconfiguration behavior
By default Windows generates a random interface ID for
Non-temporary autoconfiguration addresses (permanent)In other words – it doesn’t do EUI-64
Because the host randomly built an interface IDIt starts using it right awayIt doesn’t wait for duplicate address detection (DAD)
Autoconfiguration is used to build link-local and can be used for global and ULA (depending on the flags A/M/O)
Windows specific Autoconfiguration behavior
If you are using a Windows Server as an IPv6 routerWindows always sets the A flagThis means that the RA is enabling SLAACBy default all hosts on that subnet will build out a random permanent address and random temporary address
Windows Server 2008 and Window Vista do not attempt stateful DHCPv6 if no RA advertisement are received
SLAAC + DHCPv6 w/ O flag
2001:470:1f05:d37::/64 gets a permanent and temporary
2001:470:82a9:7::/64 gets a permanent and temporary
The router only has 2001:470:82a9:7::/64 as an address
Cisco IPv6 SLAAC + DHCPv6 w/ O flag config
interface Vlan7 description - work - ipv6 address 2001:470:82a9:7::/64 and 2001:470:1f05:d37::/64 ipv6 address 2001:470:1F05:D37:2::1/64 ipv6 enable ipv6 nd prefix 2001:470:1F05:D37::/64 300 300 ipv6 nd prefix 2001:470:82A9:7::/64 300 300 ipv6 nd other-config-flag ipv6 dhcp server HE Setting the O flag

interface Vlan7 description - work - ipv6 address 2001:470:82a9:7::/64 ipv6 address 2001:470:82A9:7::1/64 ipv6 enable
By default the A flag is enabled
IP Address Management (IPAM)
It is normal for a single host to have 3 or more IPv6 addresses
Each /64 subnet can have 18 million trillion addresses
I don’t think you want to manage a spreadsheet with 18 million trillion fields for 128 bit long addresses in HEX
If you don’t want to do that use an IPAM solution!

Why is Path MTU so important in IPv6?
MTU = 1500
MTU = 1400
MTU = 1400
MTU = 1500
Set your MTU to 1400
Important ICMPv6 Things to Know
Path MTU must be allowed or IPv6 will break
&
This means you need to allow ICMPv6 traffic through your network
IPv6 DNS
An IPv6 address record in DNS is AAAA
The PTR zone is IP6.ARPA.
Why is it AAAA?An A record in IPv4 represents 32 bitsIPv6 has 128 bits so 4 A’s make 128
IPv6 Reverse DNS
Examples:2001:470:1f05:d37:202c:7674:c4c2:4fa82001:470:1f05:d37::1
The reverse entry in IP6.ARPA. looks like:8.a.f.4.2.c.4.c.4.7.6.7.c.2.0.2.7.3.d.0.5.0.f.1.0.7.4.0.1.0.0.2.IP6.ARPA.1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.7.3.d.0.5.0.f.1.0.7.4.0.1.0.0.2.IP6.ARPA.
Every nibble must be included so:Zero compression has to be expanded back outLeading zeros must be added back in
How Does a Windows Client get DNS Servers?
DNS Servers are obtained via DHCPv6 w/ O or M flag
If there is no DHCPv6 then:
the DNS is manually configured

Dual Stack
You run IPv6 and IPv4 side by side
You let the host decide which protocol to use
For routing the two protocols operate like ships in the night
You will consume more resources to run dual stack
You have to understand how your applications behave
Dual Stack
Windows 8 and Windows Server 2012 have RFC 6555 implemented (Happy Eyeballs)
All applications benefit from Windows 8 and Windows Server 2012 having RFC 6555 enabled
You have to use RFC 3484 and RFC 6555 and the Internet draft update for RFC 3484 to determine app behavior
Dual stack is a transition technology – the eventual goal is only IPv6
Dual Stack
Tunneling Translation
NativeIPv6
Tunneling
In Windows there are three main tunneling transition technologies
6to4ISATAPTeredo
All of these enable IPv6 to IPv6 communication they just use IPv4 as a transport
I recommend turning off all the transition tunneling technologies to avoid problems troubleshooting IPv6
Turning off 6to4
PowerShell for Windows Server 2012 and Windows 8
Set-Net6to4Configuration-State Disabled
Netsh for Windows Server 2008 R2, Windows Server 2008, Windows 7, Windows Vista
Netsh interface 6to4 set state disabled
Set the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\DisabledComponents registry value to 0x2 (DWORD) (and then restart the computer)
Turning off 6to4
Windows Server 2012, Windows Server 2008 R2, Windows 8, or Windows 7
Set the 6to4 State Group Policy setting in Computer Configuration|Policies| Administrative Templates|Network|TCP/IP Settings|IPv6 Transition Technologies to Disabled
Turning off ISATAP
PowerShell for Windows Server 2012 and Windows 8
Set-NetIsatapConfiguration-State Disabled
Netsh for Windows Server 2008 R2, Windows Server 2008, Windows 7, Windows Vista
Netsh interface isatap set state disabled
Set the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpip6\Parameters\DisabledComponents registry value to 0x4 (DWORD) (and then restart the computer)
Turning off ISATAP
Windows Server 2012, Windows Server 2008 R2, Windows 8, or Windows 7
Set the ISATAP State Group Policy setting in Computer Configuration|Policies| Administrative Templates|Network|TCP/IP Settings|IPv6 Transition Technologies to Disabled
Turning off Teredo
PowerShell for Windows Server 2012 and Windows 8
Set-NetTeredoConfiguration-Type Disabled
Netsh for Windows Server 2008 R2, Windows Server 2008, Windows 7, Windows Vista
Netsh interface teredo set state type = Disabled
Teredo client on managed networks (AD is present) is disabled by default
Turning off Teredo
Windows Server 2012, Windows Server 2008 R2, Windows 8, or Windows 7
Set the Teredo State Group Policy setting in Computer Configuration|Policies| Administrative Templates|Network|TCP/IP Settings|IPv6 Transition Technologies
Tunneling
So why do I recommend turning off all the transition tunneling technologies?
Unless you have a specific design build around them they introduce unpredictable behavior
Still leave IPv6 enabled, just disable the transition tunneling, that way when it is time to deploy IPv6 you don’t have to touch the hosts again
Dual Stack
Tunneling Translation
NativeIPv6
Translation
In Windows there is one main translation technology
NAT64/DNS64
Additional Enterprise translation technologies to know
SLB64 & NPTv6
These do IPv6 to IPv4 translation (think of them as a proxy)
NAT64/DNS64 and SLB64
NPTv6 performs limited Prefix only NAT
NAT64/DNS64
Windows Server 2008 R2 with Forefront UAG is capable of doing NAT64/DNS64
Windows Server 2012 is capable of doing NAT64/DNS64
NAT64 allows an IPv6 host to access an IPv4 host through a NAT64 devices that proxies the session
DNS64 builds synthetic AAAA records for an IPv4 A record if no IPv6 AAAA record exists
Dual Stack
Tunneling Translation
NativeIPv6
Migration
You want to move away fromTunnelingTranslation
To Dual Stack
Eventually you will want to move from Dual Stack toNativeTranslation (as needed) for older IPv4 only hosts

Planning and Design
Plan IPv6 like any other IT Project
Do not use IPv4 design rules for IPv6
Build a lab – you will need it
Test and understand your software
Make sure you have the same SLA for IPv6 as IPv4
Deployment
Start with forgiving applicationsDNS and SMTP vs. Web Services
You need to understandDual Stack behaviorTransition technology behaviorImpact on your hardware and software
Do the heavy lifting in the lab – don’t try out IPv6 in your production network!
Remember – IPv6 is used FIRST so mistakes have
immediate impact!
Deployment
DO NOT TURN OFF IPv6!
Windows Commands with IPv6 Support
PingPathpingTracertNslookupIpconfigRoute printNetsh
Windows IPv6 Caveats and Notes
Windows will use 6to4 if it has a public IPv4 address
Make sure to add your IPv6 Prefixes to AD Sites and Services/Sites/Subnets
Windows does NOT support RFC 6106 which provides DNS information in SLAAC RA’s
Windows has a native DHCPv6 client
Windows IPv6 Caveats and Notes
Important thing to know:
Windows has IPv6 enabled by default
&
IPv6 is Preferred!
DirectAccess and IPv6
IPv6 is required for DirectAccess
There are two OS deployment options for DirectAccess
Windows Server 2008 R2 and optionally Forefront UAG to utilize NAT64/DNS64Window Server 2012 now has NAT64/DNS64 built in
The first iteration of DirectAccess required hosts that DA client’s needed to reach must run IPv6
Because of NAT64/DNS64 this is no longer the case
DirectAccess and IPv6
DA clients still use IPv6 but then use NAT64/DNS64 to talk to IPv4 only hosts
DA clients can utilize Native IPv6, and all of the tunnel transition technologies plus IP-HTTPS to connect back to the DA server
IPv6 is still the main transport method but because DNS64/NAT64 is available the internal servers are not required to run IPv6
Where is IPv6 used in DirectAccess today? DA Client

Exchange and IPv6
Exchange 2007 and 2010 will prefer IPv6 for same subnet traffic
Even if you only have static IPv4 addresses configuredYou likely didn’t even notice unless you disable IPv6
Exchange Edge Transport role is a special IPv6 caseIf you have it running in a DMZ that uses Public IPv4 addresses it will attempt to use 6to4This means if someone has a AAAA record published for their MX in DNS the Exchange server will FIRST use 6to4 to attempt delivery
Exchange and IPv6
If IPv6 is enabled and is being routed properly make sure your advanced firewall is ON!
Make sure to test reachability from all networks prior to turning up IPv6 for client access networks
Test all Exchange services for both IPv4 and IPv6
If you are using IPv4 Load Balancers make sure you do the same for IPv6 or you might get strange behavior in clients
IPD’s and IPv6
Microsoft currently does not call out separate IPv6 deployment configurations in the IPD’s
My understanding is that there are plans to publish specific IPD guidelines to show the impact of disabling IPv6 in certain deployment scenarios
In the meantime, you will have to determine the ramifications of disabling IPv6 for each IPD
So What Does Microsoft Recommend?
Microsoft no longer tests their software with IPv4 ONLY networks
Microsoft has standardized on dual stack support
There are only three products that have been delay in broad IPv6 support
Forefront TMGLyncWindows Phone 7
What impact will disabling IPv6 have on me?
Recent anecdotal information about Microsoft support cases indicates customers disabling IPv6 and then having operational problems has grown dramatically
Make sure you test the planned configuration with IPv6 disabled in a lab
Do NOT randomly turn it off in your production environment – bad things can happen!
Windows 8 and Windows Server 2012
Continued high quality IPv6 support
Improved PowerShell commands
Additional performance benefits by supporting Happy Eyeballs (RFC 6555) like behavior
How does Happy Eyeballs work?
IPv6
IPv4
IPv4
IPv6
DNS Lookup:www.example.co
mHas both A and AAAA records
Client sends both IPv6 and
IPv4 requests at the same time
IPv6 works and there
isn’t significant delay then it is used
If IPv6 doesn’t work or has a big delay then IPv4 is used
How is it implemented in Windows 8?
It makes use of the same process that tells the OS that Internet access is available or that you might have to log in to gain Internet access
Network Connectivity Status Indicator (NCSI)
It modifies the cache tableSorting improvements have been madePeriodic rechecks are done
All applications benefit from this new behavior
