This video is Part 2 of 2 of an extension to the Subnetting Mastery video series. This appendix covers FLSM and VLSM (Fixed Length Subnet Mask and Variable Length Subnet Mask).
In this video, we start with a typical VLSM problem: You are presented with a Network Topology, and given a required number of IP addresses for various different Networks. You then have to break up a particular network into smaller networks to accommodate each of those IP address requirements.
In the video we solve it visually using a table to illustrate and conceptualize how to solve these problems. But a lot of students asked how to do these type of problems without the table. I was happy to oblige and answered the question in a live stream teaching session. The replay is available here:

In this replay, I'll show you how to solve VLSM problems quickly and efficiently, using only pen and paper (no big tables or large drawings) -- this mimics certification exam scenarios.
A pre-requisite to this video is to understand Subnetting. The best way to learn Subnetting is to check out all the other videos in the Subnetting Mastery video series:
