Sitting down with Michael W. Lucas's Networking for System Administrators and making Anki flashcards out of them was probably the highest impact thing I did for my career last spring. It's an incredible tool, truly.

Anyone else who wants to learn just enough networking to never be 100% stumped by it again, I recommend both tools.

Can you share what your typical flashcard for the book looks like?

There's a bunch of different subtypes I've used. But one surprisingly high ROI example has been private vs public IP flashcard examples.

E.g. "10.1.0.0 - private or public?" "Private - everything in 10.0.0.0/8 is considered private". "192.169.0.0?" "Public".
