A domain name holder (or registrant) is the individual or legal entity (such as an association, company, or private individual) that registers a domain name.
To obtain a domain name, the registrant typically works through an accredited registrar, which in turn communicates with the registry, the entity responsible for managing the domain name database, such as the City of Paris for .paris.
The registrant holds the rights and responsibilities associated with the domain name they have registered.
