In the context of web development and digital marketing, a registrar is an organization or commercial entity that manages the reservation of internet domain names. A domain name registrar must be accredited by a generic top-level domain (gTLD) registry and/or a country code top-level domain (ccTLD) registry. They provide services to the public for purchasing and registering domain names, which are essential for creating websites and establishing an online presence. Registrars often offer additional services like domain hosting, privacy protection, and domain management tools.
