IPv4 – Subnetting in Action – Part 2

When using Variable Length Subnet Masking, it is important to put your subnets in decreasing order, otherwise subnetting will fail. In this second video in the series, I show you why this is important, as we deliberately make a mistake and see what happens.

Subnetting is a very big part of IPv4, and in order to become proficient at it, it’s important to first understand why it is required, and how it works. If you haven’t done so yet, take a look at my series of videos covering the why, and the how of IPv4 subnetting. You can find links to these videos further down in the description. Keep at it to become proficient in the process and to be able to create your own subnets and IPv4 address spaces.
