What is a domain extension?

[DustinKelly]

Definition: A top-level domain (TLD), also referred to as a domain extension, is the suffix that follows the domain name in a web address; the most widely-used is ".com". TLDs are managed by the Domain Name System of the Internet, which controls how domain names are translated into Internet Protocol, or IP, addresses.

Domain extensions are the letters that follow the final period in a URL. Common extensions include .com, .org, and .net.

Another term for a domain extension is a top-level domain. That’s because you can think of the parts of a domain name as classification levels.

At the top, we have domain extensions. At this level, domains are divided into broad categories.

For example, the domain extension .de puts the domain in the “German” category. Using .gov means the domain is in the “American governmental organization” category.

Domain extensions aren’t always used this way anymore — we’ll get to that in a bit — but it was the original intention.

A domain extension is the combination of characters following the period in a web address. Domain name extensions are the last part of a domain name. For example, in ‘google.com,’ the domain name extension is .com.
Types of domain name extensions:
1. Generic Domain Extensions
2. Sponsored Domain Extensions
3. Generic-Restricted Domain Extensions
4. Country Code Domain Extensions
