Beej's Guide to Networking is introduced as reference material by many university networking courses. It's nowhere authoritative near Richard Steven's books. It's not formal writing, but that is also a feature to introduce the subject in a more lively way so as not to bore readers. For starters, that's pretty sufficient.
