I've always wanted to write a book and this would be an interesting idea ;) There's definitely a lot of cool history to cover (donno if Code covers a lot of history, haven't read it)

In the mean time I've heard this is good:

And then there's your computer network textbooks like:

I have the second edition sitting on a shelf and couldn't get anyone to buy it on ebay ;)

And this one will fill out your knowledge on the routing side, although it is rather dry: https://www.amazon.com/Network-Routing-Algorithms-Architectu...
