Domain Names

A name that identifies one or more IP addresses . For example, the domain name microsoft.com represents about a dozen IP addresses . Domain names are used in URLs to identify particular Web pages . For example, in the URL http://www.evarkul.com/index.html, the domain name is evarkul.com.

Every domain name has a suffix that indicates which top level domain (TLD) it belongs to. There are only a limited number of such domains. For example:

         gov - Government agencies

         edu - Educational institutions

         org - Organizations (nonprofit)

         mil - Military

         com - commercial business

         net - Network organizations

         ca - Canada s

         th - Thailand

Because the Internet is based on IP addresses, not domain names, every Web server requires a Domain Name System (DNS) server to translate domain names into IP addresses.
