An IP address is a 32 bit address used by TCP/IP to uniquely identify the location of a device on a network. Note that the IP address does not refer to the device itself. If, for example, you relocate a PC to another area of the same network, you may need a new IP address. The structure of this 32-bit address varies depending upon the size of the network on which the device is located. From largest to smallest, network types are referred to as Class A, Class B, Class C, and Class D. Within each class, a certain number of bits identifies the class, the network and the local address.
