A domain suffix is the last part of a domain name that comes after the final dot. It identifies the top-level domain (TLD) and indicates the type or origin of the website. Examples include .com, .org, .edu, and .gov.

Detailed Explanation of Domain Suffixes

A domain suffix is also known as a top-level domain (TLD). It is the portion of a web address that appears immediately after the final dot. The suffix helps classify the domain based on its purpose, organization type, or geographical location. For example, .com is used for commercial entities, .org for organizations, and .uk for websites based in the United Kingdom. Every domain name must include a valid suffix to be recognized by the Domain Name System (DNS). The Internet Corporation for Assigned Names and Numbers (ICANN) manages the assignment and approval of domain suffixes globally. Choosing the right domain suffix helps improve recognition, search engine visibility, and user trust.
