IP Address
The Internet Protocol (IP) address consists of two portions:
• a network portion
• a location portion
In the analogy of a telephone number, there is an area code and a phone number. Unlike
a telephone number, the network (or area code) portion of an IP address can be set to
dierent numbers of digits. It is not a fixed size like an area code. The location portion is
the rest of the number – everything that is not part of the network portion. The definition
of what is network and what is location is done by the network mask, described below.
