What is a top level domain name (TLD)?

A top-level domain (TLD) is the last segment of a domain name, situated after the final period. It represents the highest level in the domain name system hierarchy and classifies domain names according to their purpose or geographical location. Common TLDs include .com (for commercial websites), .org (for organizations), .net (for networks), .edu (for educational institutions), and .gov (for government entities). Country-code TLDs (ccTLDs) are used to denote specific countries or territories, such as .au (Australia), .nz (New Zealand), or .jp (Japan).
