I have a few Windows 2012 systems in my domain that are not dynamically updating their records in the ip6.arpa
zone for their assigned IPv6 addresses.
I have systems that are publishing their record just fine. So I am pretty confident that the problem isn't on the DNS server side.
On the systems that are not working I have verified with Wireshark, and Windows is not sending the Dynamic DNS update for the ip6.arpa
zone after running ipconfig /registerdns
, but an update is sent and acknowledged as successfully for the IPv4 reverse zone, and the domains forward zone.
I am looking for reasons why systems would not be attempting to register their IPv6 address.
The systems have a valid working IPv6 address and can access IPv6 resources on the Internet. The Register this connection's address in DNS
box is checked. From what I can see through the GUI, the same settings exist for working, a system that is working and not working.
