2-1-4. IP Address Assignment

For IP address configuration, there are three parameters needed to be filled

in. They are IP address, Subnet Mask, Default Gateway and DNS.

IP address:

The address of the network device in the network is used for internetworking

communication. Its address structure looks is shown in the Fig. 2-8. It is “classful”

because it is split into predefined address classes or categories.

Each class has its own network range between the network identifier and

host identifier in the 32 bits address. Each IP address comprises two parts: network

identifier (address) and host identifier (address). The former indicates the network

where the addressed host resides, and the latter indicates the individual host in the

network which the address of host refers to. And the host identifier must be unique

in the same LAN. Here the term of IP address we used is version 4, known as IPv4.

With the addressing, it divides IP address into three classes, class A, class B

and class C. The rest of IP addresses are for multicast and broadcast. The bit

length of the network prefix is the same as that of the subnet mask and is denoted

as IP address/X, for example, 192.168.1.0/24. Each class has its address range

described below.

Class A:

Address is less than 126.255.255.255. There are a total of 126 networks can

be defined because the address 0.0.0.0 is reserved for default route and

127.0.0.0/8 is reserved for loopback function.
