Class A Address
0-127 O is the subnet Identifier 127 is the loop back address. Each class A address supports 16,387,064
hosts. Assigned to large corporation example 95.27.27.1

Subnetting
Why: to break a network into smaller and more manageable subnets.
How: by borrowing bits from the host section. Problems:
– Routers are not aware of subnetting plans. (Can be solved)
– Loss of IP addresses. (Solution under development)

Subnet Mask
Used to filter and identify the network address and the sub network address.
How: – Special Format; All the pits in network and sub
network area will be turned on.(Continuous string of binary 1 digits)
– Binary And the Subnet mask and the IP address. (Only 1 + 1 =1)
