IP Subnetting Part 3: Understanding the Binary

Paul Stewart of PacketU comments:

I’ve often stated how simple subnetting really is. While each individual concept is rather simple, it is the combination that make the holistic process challenging. If we, as humans, could look at the process more like computers and network devices, subnetting would be a much simpler process. In short,  some knowledge of binary is an important requirement prior to sharing more complex subnetting examples.

This article will  demonstrate  the process of converting binary to and from the more familiar decimal numbering system. This will establish the necessary baseline knowledge required to understand when  applying subnet masks to IP addresses.

Read through Paul’s article on binary. If you work in tech, you will be using binary in the future.
