Domains related information

ICANN, the Internet Corporation for Assigned Names and

Numbers. It's a consortium (non-profit corporation) that

manages the assignment of domain names and IP address

ranges on behalf of the community.

When registered, your domain name will be immediately

stored in the public WHOIS database. Some of your details

will become available to the general  public immediately after.


A domain name registrar is an organization or commercial

entity that manages the reservation of Internet domain

names. A domain name registrar must be accredited by a

generic top-level domain (gTLD) registry and/or a country

code top-level domain (ccTLD) registry. The management is

done in accordance with the guidelines of the designated

domain name registries.


The Domain Name System is a distributed database, but there

are central name servers at the core of the system (see How

DNS Works for details). Someone has to maintain these

central name servers to avoid conflicts and duplication.

In 1993, the U.S. Department of Commerce, in conjunction

with several public and private entities, created InterNIC to

maintain a central database that contains all the registered

domain names and the associated IP addresses in the U.S.

(other countries maintain their own NICs (Network Information

Centers) -- there's a link below that discusses Canada's

system, for example). Network Solutions, a member of

InterNIC, was chosen to administer and maintain the growing

number of Internet domain names and IP addresses. This

central database is copied to Top Level Domain (TLD) servers

around the world and creates the primary routing tables used

by every computer that connects to the Internet.

A WHOIS search will provide information regarding a domain

name, such as example.com. It may include information, such

as domain ownership, where and when registered, expiration

date, and the nameservers assigned to the domain.
