Detailed explanation-1: -Class C network numbers are appropriate for networks with few hosts–the maximum being 254. A class C network number occupies the first three bytes of an IP address.
Detailed explanation-2: -A Class C address consists of a 24-bit network address and an 8-bit local host address. The first three bits in the network address indicate the network class, leaving 21 bits for the actual network address. Therefore, there are 2, 097, 152 possible network addresses and 256 possible local host addresses.
Detailed explanation-3: -If the address is written in decimal format, the first number determines the address. If the first number is between 0 and 127 inclusive, the address is class A. If the first number is between 128 and 191 inclusive, the address is class B. If the first number is between 192 and 223 inclusive, the address is class C.
