Calculating Subnets w/Python3

Welcome back, everyone!

Code (my GitHub): https://github.com/nmsinger/subnet-ma...
Online subnet calculator: https://www.subnet-calculator.com/

Today we cover the bit for bit representation of network addresses and get into how subnet masks work at a binary level. The ability to convert from base 10 to base 2 and from dotted decimal to binary is critical if you want to calculate ranges by hand. Even if you use an online calculator to determine your subnet ranges if you really want to understand what's going on this video should help you get there.

We cover three addresses and then get into the code, going through both classful and classless subnets. Ultimately this expands on the video from Monday about ARPANET and the beginnings of the internet, getting into modern network concepts. As a bonus, we go over some advanced Python format strings and representing binary data in different formats.
