How does a registrar update the gtld name servers?

  • 772

Is there a standardized protocol how a registrar updates the NS information for a domain? For example, if, through my registrar's interface, I set the name servers for "example.com" to "ns1.example.com" and "ns2.example.com" how are [a-m].gtld-servers.net updated with this information? Does this protocol use the whois information or is that merely informational for the end user?

Edit: I see rfc3375 "Generic Registry-Registrar Protocol Requirements" but that is informational.

    I don't know the exact details or implementations, but my understanding is that it revolves around EPP - Extensible Provisioning Protocol

    The motivation for the creation of EPP was to create a robust and flexible protocol that could provide communication between domain name registries and domain name registrars. These transactions are required whenever a domain name is registered or renewed, thereby also preventing domain hijacking. Prior to its introduction, registries had no uniform approach, and many different proprietary interfaces existed.
