What is a Registrar and How Do They Manage Domain Names?

A registrar is an entity that manages the domain name system (DNS) and provides services such as domain name registration, renewal, transfer, and management. Registrars are accredited by the Internet Corporation for Assigned Names and Numbers (ICANN) and are responsible for maintaining the database of registered domain names. They also provide technical support and customer service to their customers.

Registrationist is a term that is sometimes used interchangeably with registrar, but it can also refer specifically to an organization or individual that manages the registration of a particular top-level domain (TLD). For example, VeriSign is the registrationist for the .com and .net TLDs.

In summary, a registrar is an entity that manages domain name registration and other related services, while a registrationist may be a specific organization or individual responsible for managing the registration of a particular TLD.
