Nameserver Predelegation Check Web interface
You can use the NAST Web interface to carry out a Nameserver Predelegation Check. During this check, the name servers of your zone (domain) will be subjected to various tests in order to verify that they are configured correctly and can be delegated easily and securely. This guarantees a high quality level for the domain.Please enter the name of your domain in the form. Indication of the name servers is optional. If the name servers are not indicated, they will be retrieved automatically from the DNS. Of course this is only possible for domains that have already been registered.
The time required to verify a complete zone may amount up to 35 seconds.
