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.

Host ID with all the digits being 0 indicates that the IP
address is the network address, and is used for
network routing.
Host ID with all the digits being 1 indicates the
broadcast address, i.e. broadcast to all hosts on the
network.
IP address 0.0.0.0 is used for the host that is not put
into use after starting up.
The IP address with network number as 0 indicates the
current network and its network can be cited by the
router without knowing its network number.
Network ID with the format of 127.X.Y.Z is reserved for
self-loop test and the packets sent to this address will
not be output to the line. The packets are processed
internally and regarded as input packets.
Host ID with all the digits being 0 indicates that the IP
address is the network address, and is used for
to network routing.
Host ID with all the digits being 1 indicates the
broadcast address, i.e. broadcast to all hosts on the
network.
Host ID with all the digits being 0 indicates that the IP
address is the network address, and is used for
