IP Address

An IP address is a unique 32-bit address assigned to a computer and includes:

•A network ID number identifying a network.

•A host ID number identifying a computer on the network.

All IP addresses have been divided into three smaller groups (classes) A, B and C

•Class A addresses have 8-bits of network ID and 24-bits of host ID. They can support a large number of hosts, approximately 2 = 16,777,216 computers per network.

The IP addresses range in binary from 00000001.xxxxxxxx.xxxxxxxx.xxxxxxxx to 01111111.xxxxxxxx.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 1.x.x.x to 127.x.x.x

Class A network ID’s support a very large number of hosts.

•Class B addresses have 16-bits of network ID and 16-bits of host ID. They can support approximately 216 = 65,536 computers per network.

The IP addresses range in binary from 10000000 00000000.xxxxxxxx.xxxxxxxx to 10111111 11111111.xxxxxxxx.xxxxxxxx

The IP addresses range in decimal from 128.0.x.x to 191.255.xxx.xxx

Class B network ID’s support a medium number of hosts.

•Class C addresses have 24-bits of network ID and 8-bits of host ID. They can support approximately 28 = 256 computers per network.

The IP addresses range in binary from 11000000.00000000.00000000.xxxxxxxx to 11011111.11111111.11111111.xxxxxxxx

The IP addresses range in decimal from 192.0.0.xxx to 223.255.255.xxx

Class C network ID’s support a small number of hosts.

The rest of the addresses are divided into two classes, D and E. Class D networks are not assigned to the host. They are used for multicasting.

The address range from 224.x.x.x to 239.x.x.x

Class E networks are experimental or reserved addresses.

The address range from 240.x.x.x to 247.x.x.x
