Where, Class A, Class B and Class C are unicast addresses, while Class D addresses
are multicast ones and class E addresses are reserved for special applications in future.
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, e.g.10.110.50.101.
When using IP addresses, it should also be noted that some of them are reserved for
special uses, and are seldom used. The IP addresses you can use are listed in the
following table.
