Hey Friends,

Some of you are familiar with the Subnetting Mastery video series. I have now extended this series to also include a two-part appendix covering FLSM and VLSM.

Subnetting Mastery - FLSM and VLSM - Appendix Part 1 of 2

This video covers how to answer questions that look like this:

• If you start with a /18, what size sub-network would you need to create 100 sub-networks?
• If you start with a /10, how many sub-networks could you create that were each /16?

First, I'll show you a simple way of solving these questions. Then at the end of the video I'll show you a shortcut that let's you solve these questions lightning fast.

This video also contains crucial knowledge that will be needed to understand VLSM questions, covered in the next video.

Links to this video, and all the other videos in the Subnetting Mastery video series (which should be considered a pre-requisite before watching the FLSM and VLSM videos), as well as an IPv4 problem generator are available here:

Hope it helps, would love to hear your thoughts =)
