captive.renner.uno has the identical problem just fixed for udm: UniFi
auto-serves only its A record (captive -> 192.168.8.1, the UDM console)
and forwards AAAA upstream, where the *.renner.uno wildcard returns
proxy.renner.uno. Pin the AAAA to the UDM management ULA fd00::1 so
v6-first clients reach the UDM instead of the public reverse proxy.
Same value as udm because both names resolve to the same UDM console
(192.168.8.1 over v4; fd00::1 is its v6, verified serving the controller).
