Domain Registrar

A domain name registrar is an organization that manages the reservation of Internet domain names, supervised by the Internet Corporation for Assigned Names and Numbers (ICANN).

Most registrars will also offer authoritative DNS hosting so their clients can make use of the domain, though this is not implied from the registrar role.

There are several registrars with similarly good prices and user experience: Hover, Gandi.net, Freenom, Porkbun, NameCheap, DNSimle, Google Domains etc.
