TCP/IP Frequently Asked Questions

Table of Contents

This is the Table of Contents for the Frequently Asked Questions (FAQ) list for the comp.protocols.tcp-ip Usenet newsgroup. The FAQ provides answers to a selection of common questions on the various protocols (IP, TCP, UDP, ICMP and others) that make up the TCP/IP protocol suite. It is posted to the news.answers, comp.answers and comp.protocols.tcp-ip newsgroups on or about the first Friday of every month.

The FAQ is posted in two parts. Part 1 contains answers to general questions and questions that concern the fundamental components of the suite. Part 2 contains answers to questions concerning common applications that depend on the TCP/IP suite for their network connectivity.

Comments on this document can be emailed to the FAQ maintainer at <>.
