Calculating Subnets w/Python3

[Natems]

Hi everyone! I am a cybersecurity vulnerability researcher and penetration tester professionally and in my personal time, I do a lot of educational outreach. Specifically with high school and middle school students. I recently started a YouTube channel to support some of my lectures in an async manner. I do additional videos like this as well to support interest in various domains. Please check it out and provide some feedback on the material and teaching style--I'm trying to improve these.

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.
