This is Video 3, and the cornerstone, of the Subnetting Mastery video series. In this video, we will show you how to use the Subnetting Cheat Sheet to solve for all seven attributes of Subnetting: Network ID, Broadcast IP, First Host IP, Last Host IP, Number of IP Addresses, Next Network, and CIDR to Subnet Mask conversions.
Each of these attributes were defined in Video 1 of the series. EVERY Subnetting problem you encounter is simply asking you to solve for one or more of these seven attributes. In this video, we'll show you how to solve for all seven in 60 seconds or less.

I am amazed! You have explained a binary math problem without ever mentioning binary math. Whenever I tried to explain the terminology to someone I have lost them if not by mentioning the binary system, then certainly when I start the story about the four 8-bit registers and weight of each position. Essentially I have done in my head that what your cheatsheet does, but without ever writing it down I did not realize that someone without understanding binary could just remember how to write the table and use the table. Excellent video, I've subscribed.

Quick tip for those learning, you can add the # of available networks per mask size /CIDR, by adding another row above that 'doubles' in each column beginning with '2' above the 128 in the group size row to see the number of available networks that mask allows. Hope that helps anyone. Ed obviously has done a tremendous job; I just figured I'd add something from the cheat sheet my instructor used in school (if Ed has no objections). And the '2' would go in the 128 bits column in the relevant octet.
