Note: Class D & E should NOT be assigned to network assignment of IP

definition, the first node number (i.e., "0") is used to define the network

Note: Public addresses can include a network address assigned from the net-
work administrator or from the IP provider. Also, there is one network in
each class that is defined for private use, allowing the creation of
internal networks. These addresses are Class A: 10.0.0.0, Class
B:172.6.0.0, and Class C: 192.168.0.0.
