commercial addresses and are assigned to hosts. Class D is reserved for
multicast use and Class E is for experimental use. Class C addresses have three octets for the network portion and
onefor the hosts. The default subnet masks is 24 bits ( 255.255.255.0 ) Class C
addresses are usually assigned to small networks.

Class B address have two octets
to represent the network portion and two for the hosts. The default subnet masks
16 bits ( 255. 255. 0.0 ). These addresses are typically used for medium –sized
networks. Class A addresses have only one octet to represent the network portion
and three to represent the hosts. The default subnet masks is 8 bits ( 255.
0,0,0 ). These addresses are typically assigned to large organizations.
