I’m a software developer who works with OS networking primitives - which books would you recommend to learn more about how networks work at a protocol level (IP, TCP/UDP/ICMP) and at a lower level.

I’ve been doing a lot of work recently with raw sockets and writing code that interacts with raw bytes from over the wire. I want to learn more about the protocol level and sub-protocol level of networking to help my understanding of how systems communicate.

I’ve looked at books such as Internetworking with TCP/IP Volume One: 1 and TCP/IP Illustrated, Volume 1: The Protocols: The Protocols v. 1, but wanted to see if there were any suggestions that would give good comprehensive coverage of the stack from socket programming downwards that were also relatively modern and covered modern hardware and protocol capabilities.
