Everything you ever wanted to know about subnetting and masks, also a few things you didn’t want to know, too.

Some of you have probably heard of the term Subnetting and some of you may even know what it is. There are statistics that show if you have heard of subnetting, then there is a larger-than-not chance that you also have no life.

This post will assume that you have not heard of subnetting and have no idea what it is (and that you lead a rich and fulfilling existence). This concept will include certain things like IP addresses and binary math but the general philosophy behind subnetting is based in security (through separation) and displays how necessary subnetting and masking is for IPv4 networking.

The term subnet and subnetting is sort of a generic term that encapsulates breaking the entire IP addressing scope into smaller divisions. To understand subnetting, we have to take a step back and understand IP addressing, binary math and the scope of the whole thing.
