IP address
Internet Protocol (IP) address is an identifier for a computer
or device on a TCP/IP network. Networks using the TCP/IP
protocol route messages based on the IP address of the
destination. The format of an IP address is a 32- bit numeric
address written as four numbers separated by periods. Each
number can be from 0 to 255. For example, 1.160.10.240 can
be an IP address.
Within an isolated network, you can assign IP addresses at
random as long as each one is unique. However, connecting
a private network to the Internet requires using registered
IP addresses to avoid duplicates. The four numbers in an IP
address are used in different ways to identify a particular
network and a host on that network. The InterNIC
Registration Service assigns Internet addresses from the
following three classes.
Class A
Class A supports 16 million hosts on each of the
127 networks.
Class B
Class B supports 65,000 hosts on each of the
16,000 networks.
Class C
Class C supports 254 hosts on each of the 2 million
networks.
