Does ZADNA register .za domain names?
No, ZADNA only administers and manages the .za namespace. This includes developing regulations, policy and procedures for .za, and the licensing of .za registries and registrars.
The process of registration of domain names usually requires that a person interested in a particular domain name registers such name using an Internet service provider (normally called “registrar”). The registrar then registers the name in an SLD database. A registry manages an SLD database.
