What would be a good list of books to learn how the Internet works?

I’m specifically looking for things that aren’t covered in CISCO training. I think CISCO, Juniper, etc gets me up to layer 4. But I want to know the whole thing.

Right now I’m doing CCNA for the bottom four layers. But what are some good books to read in order to understand:

-the upper layers -how TCP/IP works -how the Internet works

Once I have that and I have CCNA then I think that’s plenty of networking and then I can be more prepared to go into python network programming, which I will ask about later.

UPDATE:

This isn’t for career questions. I like to learn networking and I want to eventually learn network programming as well.
