BSD Sockets: A Quick And Dirty Primer58 (Unix system programming info, too!)
And here are some relevant Wikipedia pages:
Transmission Control Protocol (TCP)64
User Datagram Protocol (UDP)65
Serialization67 (packing and unpacking data)
RFCs68—the real dirt! These are documents that describe assigned numbers, programming APIs, and protocols that are used on the Internet. I’ve included links to a few of them here for your enjoyment, so grab a bucket of popcorn and put on your thinking cap:
RFC 169 —The First RFC; this gives you an idea of what the “Internet” was like just as it was coming to life, and an insight into how it was being designed from the ground up. (This RFC is completely obsolete, obviously!)
RFC 76870 —The User Datagram Protocol (UDP)
RFC 79171 —The Internet Protocol (IP)
RFC 79372 —The Transmission Control Protocol (TCP)
RFC 85473 —The Telnet Protocol
RFC 95974 —File Transfer Protocol (FTP)
RFC 135075 —The Trivial File Transfer Protocol (TFTP)
RFC 145976 —Internet Relay Chat Protocol (IRC)

RFC 261679 —Hypertext Transfer Protocol (HTTP)
RFC 282180 —Simple Mail Transfer Protocol (SMTP)
RFC 333081 —Special-Use IPv4 Addresses

RFC 397786 —Network News Transfer Protocol (NNTP)
RFC 419387 —Unique Local IPv6 Unicast Addresses

The IETF has a nice online tool for searching and browsing RFCs89.
