The Registar, is the company that offers domains name registration to individuals and businesses.

There are different types of Registrars, officials like DonDominio, which have official accreditation in the various Registries and manage the domains directly, and Resellers, who contract the domains to other companies, this type of registration does not have direct control over the domain, so in the event of any type of problem or issue can not manage the solution quickly, they must escalate the incident to the Registrar used in the domain registration, extending the reaction time to solve it.
