Understanding Top-Level Domains

A Beginner’s Guide – A comprehensive introduction explaining what TLDs are and how they function in the domain name system.

What is a Top-Level Domain (TLD)?


A Top-Level Domain (TLD) is the concluding portion of a domain name, such as .com or .net. They are also referred to as domain extensions, suffixes, or URL extensions.

TLDs play a crucial role in identifying the nature or purpose of a website, whether it’s commercial (.com), network (.net), organizational (.org), or country-specific (.uk, .fr, .pe).
