IP Classes

With IP V4, there are not enough IP addresses for everbody. To solve this problem, subnetting is used.

IP addresses consists of 2 parts, a node address and a network address.

The class of the address and the subnet mask determine which part belongs to the network address and which part belongs to the node address.

Each class is defined by the first 4 bits of the IP address.

Class A = 0xxx, or 1 to 126

Class B = 10xx, or 128 to 191

Class C = 110x, or 192 to 223

Class D = 1110, or 224 to 239

Class E = 1111, or 240 to 254
