1.  The AutoDNS user sends a request to the domain management system AutoDNS. The domain management system immediately sends a reply with the current status E if there is an error and S if it was successful. The status N is sent if the request is still being processed.
  2.  Requests that are answered with S or E are finished when the reply is sent . Requests that are answered with an N will be further processed by the system.
  3.  The domain management system sends the request to the registry and receives the answer.
  4.  The domain management system sends a reply with the final status code S or E to the AutoDNS user.
