Question: What are Web extensions?
What are Web extensions?
Answer: Web extensions, also known as top level domain names, are the part of the URL that specifies what exactly that site is part of (institution, government, business, country, etc.).

The most well-known Web extensions are .com, .edu, .net, and .org.

  • .com: short for "commercial"; most popular Web extension
  • .org: short for "organization"; mostly non-profits, but can be used for any type of organization
  • .gov: short for "government"; usually a federal site, but also can indicate a state site
  • .edu: short for "educational"; most domains with an .edu extension are education-related
  • .net: short for "network"; many ISPs (Internet Service Provider) and networks use a .net extension.

There are many more Web extensions than this, for example, each country also has a unique Web extension assigned to them (.uk for the United Kingdom, .fr for France, etc.). For a more specific breakdown of the various kinds of Web extensions, read What is a Top Level Domain Name?.
