What RFC's do you recommend?

Question

I am just beginning to dwelve into the TCP/IP and would like to know, which RFC's the experts recommend, beside the 1812, 1122, and 1123, for a newbie who barely begins to learn about it.

Answer 1

There are several reference documents of interest in checking the status of protocol specifications and standardization:

o INTERNET OFFICIAL PROTOCOL STANDARDS
This document describes the Internet standards process and lists the standards status of the protocols. As of this writing, the current version of this document is STD 1, RFC 1780, [ARCH:7].
This document is periodically re-issued. You should always
consult an RFC repository and use the latest version of this
document.

o Assigned Numbers
This document lists the assigned values of the parameters used in the various protocols. For example, it lists IP protocol codes, TCP port numbers, Telnet Option Codes, ARP hardware types, and
Terminal Type names. As of this writing, the current version of this document is STD 2, RFC 1700, [INTRO:7]. This document is periodically re-issued. You should always consult an RFC repository and use the latest version of this document.

o Host Requirements
This pair of documents reviews the specifications that apply to hosts and supplies guidance and clarification for any
ambiguities. Note that these requirements also apply to routers, except where otherwise specified in this memo. As of this writing, the current versions of these documents are RFC 1122 and RFC 1123 (STD 3), [INTRO:2] and [INTRO:3].
