Number of bits for Class C networks — 24 bit mask = 255.255.255.0, 32 bit mask = 255.255.255.255.
USABLE SUBNETS AND ADDRESSESThe top and bottom host numbers of any subnet may not be used.The bottom number is the subnet address and the top number is thebroadcast address for the subnet.

NETWORK ADDRESS RANGES BY CLASS
IP network addresses are issued as follows:
CLASS RANGE DEFAULT MASK
Class A 1-127 255.0.0.0Class B 128-191 255.255.0.0Class C 192-223 255.255.255.0
MAXIMUM NUMBER OF HOSTS BY CLASS
The maximum number of hosts is achieved by using thedefault subnet mask for each class (i.e. by having only one subnet).
