Top-Level Domain (TLD)

What is Top-Level Domain (TLD)?

A Top-Level Domain (TLD) is the highest level in the hierarchical Domain Name System of the Internet. The segment of a domain name immediately follows the last dot symbol. TLDs are used to identify different types of websites and entities according to a standardized format. Common TLDs include:

  • .com,
  • .org, and
  • .net, info, and
  • country-specific domains such as and .ca.

In addition to being organized by type, TLDs can be divided into two broad categories: generic top-level domains (gTLD) and country code top-level domains (ccTLD). gTLDs are available for anyone regardless of geographic location, while ccTLDs must be registered with the specific government or organization associated with the country it serves.

The World Wide Web Consortium has established rules for registering domain names, which include requirements for choosing an appropriate TLD for your website or entity. These rules help keep websites organized, making it easier for users to find what they want online.
