What is the domain name?
|
|
Domain names are used to identify 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 https://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.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
· 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.
