I have a new Server 2019 domain controller running and my network has IPv4 and IPv6 functionality and a static IP address for both protocols has been configured, in DNS I can see the A and AAAA records created for the domain controller and in the reverse lookup zone for IPv4, I can see the PTR record for the IPv4 address created along with a time stamp added on to it matching today's date and the time of it's registration.
But in the reverse lookup zone for IPv6, no PTR record is created, as a result, if I do nslookup domain.contoso.com the Server shows up as UnKnown because it's preferring IPv6 and no PTR record for the IPv6 address exists. I've tried configuring the DNS Client group policies that specify it should register the PTR record regardless, register it if the A record succeeds, including setting the Refresh Interval policy to 6 hours so that it matches the Refresh Interval for DNS scavenging and fiddling with settings in the Network Adapter such as Use This Connection's DNS Suffix in DNS Registration and Register This Connections Addresses in DNS and nothing changes.
Does anyone have any ideas?
