A few folks are pointing to the RFCs. In particular, let me recommend RFC 1000 as a place to start: https://tools.ietf.org/html/rfc1000 https://tools.ietf.org/html/rfc1000 (This RFC is a reference guide for the Internet community which summarizes of all the Request for Comments issued between April 1969 and March 1987.
