IP Addresses can be classified into five classes A, B, C, D and E. Each class consists of a contiguous subset of the overall IPv4 address range. Class. Supports 16 million hosts on each of 127 networks. Supports 65,000 hosts on each of 16,000 networks. Supports 254 hosts on each of 2 million networks.
Class A. Class A addresses are assigned to networks with a very large number of hosts. The high-order bit in a class A address is always set to zero. The next seven bits (completing the first octet) complete the network ID.lass C. Class C addresses are used for small networks. The three high-order bits in a class C address are always set to binary 1 1 0. The next 21 bits (completing the first three octets) complete the network ID.
