Domain Name System

Every computer on the Internet has a unique address called its "IP address" or Internet Protocol address. IP addresses are strings of numbers.

Early Internet users found these series of numbers hard to remember. The DNS was created so a familiar string of characters (the "domain name") could be used instead. So rather than typing an IP address like "", you instead type an easy to remember name like "www.inaic.org".

The Domain Name System (DNS) helps users navigate the global Internet and connect their computers to web sites or other computers by translating domain names into valid Internet addresses.

The DNS is a distributed internet directory service. DNS is used mostly to translate between domain names and IP addresses, and to control email delivery. Most internet services rely on DNS to work. If DNS does not know all registered names on the Internet, then some web sites cannot be located and email delivery stalls. DNS is also acritical component of the Internet and in order the resolve the WHOLE Internet it is important to select a DNS that resolves all registered names. Public-Root DNS resolves the whole Internet!

A selection of overview documents explains DNS from a high-level perspective, while the RFC documents are the official standards.
