Class C IP Addressing to (2,097,152 Networks)


Having 8 bits for host addresses means that each Class C network has 256 mathematically possible host addresses. the first 3 bits of the first octet must be 110. Starting the bit pattern of the first octet with a 110 separates this space from the upper limits of the Class B space.

The highest value of the first octet is 11011111 or 223 (128 + 64 + 16 + 8 + 4 + 2 + 1)

The last octet of a Class C address represent possible host addresses within each specific network number. As with the Class B address space, the entire address must be globally unique. Individual host addresses can be duplicated within each network address.

The range of possible Class C network addresses is from to

Valid host addresses for Class C networks range from x.x.x.0 to x.x.x.255 .
