IP Address Overview IP Address Classification and Indications
An IP address is a 32-bit address allocated to the devices which access the Internet. It
consists of two fields: net-id field and host-id field. There are five types of IP address.
See Figure 61.
Figure61 Five Classes of IP Address
Class A, Class B and Class C are unicast addresses, while Class D addresses are
multicast addresses and Class E addresses are reserved for special applications. The
first three types are commonly used.
The IP address is in dotted decimal format. Each IP address contains 4 integers in
dotted decimal notation. Each integer corresponds to one byte, for example,
10.110.50.101.
