Top-level domain

From ArticleWorld

A domain name includes the letters that follow the “@” sign in your email address. The Top-Level Domain (TLD) is the group of letters that comes after the “dot.” For example, .com, .org and .gov are top-level domains. The authority that determines the classification of TLDs is known at the Internet Assigned Numbers Authority (INAA).

The INAA developed a three-part classification system that is divided as follows:

  • Generic Domains – (gTLD) – These were the first TLDs assigned as part of domain names. Examples include .org, .com and .edu.
  • Infrastructure Domain – There is currently only one infrastructure domain, .arpa. It is reserved for the Department of Defense.

The INAA receives requests for new TLDs upon occasion. One such example is the request for .love to be a new TLD.
