A domain registrar is a company that manages the reservation of internet domain names. When you want to create a website, you need a unique domain name, like example.com. The registrar helps you register this name, ensuring that it is not already taken and that you have the rights to use it for a specified period, usually one year. In addition to registering domain names, registrars often provide other services, such as web hosting, email accounts, and domain management tools. They are accredited by organizations like the Internet Corporation for Assigned Names and Numbers (ICANN), which oversees the domain name system globally.
