Domain extensions refer to the words that are typed after the domain name. Here is the list of some domain extensions with their use;
The com in dot-com is short for commercial. Dot-coms are by far the most used extension and were originally intended for domains registered to commercial organizations. With the popularization and mainstreaming of the internet, the dot-com domain became open to the public and soon grew to be the most popular top-level domain for networking, businesses, websites, and emails.
The dot-Edu domain extension was first created for educational institutions all over the world, but while American educational institutes adapted the .edu, non-U.S. educational institutions used a country-level domain instead.
The dot-net domain extension is derived from the word network. Originally, it was meant for organizations that participated in networking technologies like infrastructure companies and internet service providers. While dot-net was created for networking purposes, these restrictions were not enforced, and this extension over time became a “general purpose namespace.” Today, it is still widely used in the advertising sector and by network operators with many seeing it as a viable substitute for dot-coms.
The dot-gov name is derived from the word government, meaning that it is restricted to American governmental bodies. Since the internet began as a U.S. federal government-sponsored research network, they limited the .gov designation to only U.S. governmental federal agencies.
Agencies beneath the cabinet level needed to use subdomains of the parent agency. Over time, dot-gov became standard protocol for any governmental departments, agencies, programs, federally recognized tribes, U.S. territories, cities, towns, counties, and parishes. If other countries want to use .gov or something similar, they must use a second-level domain. For example, the United Kingdom is registered as .gov.UK
The dot-mil name is derived from the word military. Like with .gov, dot-mil is a domain name extension that is limited to the United States military branches. The DOD (department of defense) uses dot-gov as its homepage and then employs three second-level domains within the dot-mil extension for DOD, Pentagon, and defense. Other countries must use second-level domains as well. Canada, for example, uses norad.mil for the jointly operated North American Aerospace Defense Command.
The dot-org name is derived from the word organization and was first intended for non-profits. However, this constraint was not rigidly enforced and was eventually lifted. The domain was originally intended for non-profit entities, but this restriction was not enforced and has been removed. Presently, the domain is open and is regularly used by open-source projects, communities, for-profit entities, and schools.
Also there are some top level domain extensions that are rarely used for example, .name, .aero, .biz, .coop, .info, .museum, and .pro.
Also, some countries use their own domain extensions, for example, “.uk” which means Great Britain, “.ca” which means Canada, and “.fr” which means France.
