Do the numbers mean anything to you? Or is it just a set of complex numbers that helps define a computer network?

Let us find out more about and its meaning in a computer network.

Subnetting and


The most common subnet mask used for connecting Internet Protocol (IPv4) network on computers. It is used mostly for home network routers.

A subnet mask helps different devices connected to a network like the router, modem, computers, etc. (local network) communicate with remote addresses.

The traditional subnets are partitioned into one of the five classes (Class A/B/C/D/E). This depends on the value of the IP address of the number. The subnet mask converts into a 32-bit binary value.

This value is as follows:

11111111 11111111 11111111 00000000

The ‘0’ in the above value mask span the IP range of the subnet.

For example, a computer’s IP address is, the subnet mask is So, the computer and every other device in the same network will have the same IP address with the last three numbers that will vary. Similarly, the computer having a subnet mask is, and then all computer in the local network will be

Use of Subnetting

Subnetting is very useful for home networks. However, it is mostly used for larger networks having more than 255 computers in the network.
