Network Address

In every network there is a network address. The network address is the lowest IP address that is part of the network. If I had a network that had all of the addresses from 1.2.3.0 to 1.2.3.255 then the network address for that network would be 1.2.3.0. There would be 256 IP addresses that belonged to the network. Every network address ends in an even number.
