What is the best way to learn networking?

Question

I have been using several of the WebAPI's like WebSockets and WebRTC for a while, but I never fully understood what is happening behind the scenes. Today I read a HN post about WebTransport, and frankly I have to say that most of the terminology flew past my head. Where would be a good place to start learning networking in depth (from the physical layer and upwards)?

Tanenbaum's "Computer Networks" is one big book to start with (you can also press wrinkled shirts with it, hammer in small nails, it is generally a good thing to keep around the house).
