Internet Corporation for Assigned Names and Numbers (ICANN) manages the domain name system. It is a non-profit organization that creates and implements policies for domain names. ICANN permits companies called Domain Name Registrars to sell domain names. These domain registrars are allowed to make changes to the domain name registry on your behalf. Domain name registrars can sell domain names, manage their records, renewals, and transfers to other registrars. As a domain name owner, you are responsible for telling the registrar where to send requests. You are also responsible for renewing your domain registration.
