In my previous article, I have talked about all that you need to know about IP addresses in network security.

 

In this article, I want to talk about all that you need to know about IP subnetting. Follow me as we are going to look at this together in this article.

 

IP Subnetting

Subnetting is simply the process of splitting up a network into smaller portions. For example, if you have a network using the IP address 192.168.1.X ( X being whatever the address is for the specific computer) , then you have allocated 255 possible IP addresses.

 

What if you want to divide that into two separate subnetworks? This can be done through subnetting.

 

 

Technically speaking, the subnet make is a 32-bit number that is assigned to each host to divide the 32-bit binary IP address into network and node portions.

 

It does not accept random numbers. The first value of a subnet mask must be 255, 154, 252, 248, 240, 224, and 128.

 

The network IP address and the subnet mask will be accepted by the computer, which will then use a binary AND operation to combine them.

 

A subnet mask is present regardless of the fact that you might have never needed to use subnetting.

 

If you have a Class C IP address, then your network subnet mask is 255.255.255.0, and finally, if it is a Class A, your subnet mask is 255.0.0.0
