When I read this through 25 years ago I learned more about networking than I think I knew in total up until that point, and that was nearing the end of an A level (English further education) Computing course. It's a really comprehensive guide that laid it out exactly the way I needed it for me to absorb it. I still recommend it to people that might be new to network programming as the sockets API really doesn't change that much whether you're using C or Python or some other language.
