A domain suffix is the last part of a domain name. Common examples include ".com," ".net," and ".org," though many others exist. For example, country-specific domain suffixes such as ".uk," and ".se", and ".jp" can be used to identify websites located in the United Kingdom, Sweden, and Japan.

Newer domain suffixes, such as ".tv" and ".mobi" are used to identify specific types of websites. For example, the ".tv" domain suffix is commonly used by television station websites. The ".mobi" suffix is used for mobile versions of websites that can easily be viewed on mobile devices. Domain suffixes are also called "top-level domains" or "TLDs." You can view a comprehensive list of TLDs at the Sharpened.net Domain Suffixes page.

GoDaddy allows you to choose one of several different domain suffixes when you register a domain name.
