Domain Name Extension Definitions
Last modified: November 3, 2010There are a lot of Domain Name Extension Definitions, but in a nut shell, these extensions refer to the suffix or last portion of the full Internet domain name, the term or letters that follows the last dot in the URL. For instance, in www.Google.com, the domain name extension is “[dot]com.” Domain name extensions are also known as top-level domain names. There are several kinds of top level domain names, and these domain name extension definitions are explained below.
First in the list are the country code domain name extensions. As the term phrase suggest, these extensions are used by websites belonging in a country or a territory. The country code extension for United States, for example, is [dot]us, for Canada it’s [dot]ca, for India, it’s [dot]in. Almost all countries in the world have their own country code extensions.
Another type of domain name extensions are sponsored top-level domain names. These domains are specifically created by influential and huge private organizations and agencies. For instance, the extension [dot]gov is solely for the use of the United States government. Other domain name extension definitions under this umbrella are [dot]edu for academic institutions in the United States, [dot]asia for organizations and companies in the Asia Pacific, [dot]mil for the United States military, among many others.
Last type of domain extensions are generic top-level domains. These domain extensions basically have no restrictions and can be bought by everyone in the world. These extensions included in generic top-level domain names are [dot]com, [dot]info, [dot]net, and [dot]org.
