A DNS server should be authoritative for the domain it is serving. This means that the DNS server should have the most up-to-date information about the domain’s name servers and the records for the domain.

If the DNS server is not authoritative for the domain, it may not be able to provide accurate information about the domain’s name servers and records.

When a domain controller is added to a domain, it should use the DNS server for the domain that is authoritative for the domain. The DNS server for the domain should be configured with the same IP address and port as the domain controller.

This will ensure that the DNS server is able to provide accurate information about the domain.

If the DNS server for the domain is not authoritative for the domain, the domain controller should use the DNS server for the parent domain of the domain. If the DNS server for the parent domain is not authoritative for the domain, the domain controller should use the DNS server for the domain that is hosting the root domain for the domain.
