Describe the Bug

When having a private resource for test.domain.tld whilst having in public dns a wildcard A and AAAA record for *.domain.tld the IPv6 addres of the global dns stil gets resolved with resolvectl query test.domain.tld.

Environment

OS Type & Version: Truenas 25.04.2.6 (running in docker compose)
Pangolin Version: 1.15.1
Gerbil Version: 1.3.0
Traefik Version: 3.6.7
Newt Version: 1.9.0
Olm Version: cli client 0.3.0 (Linux x86_64)

To Reproduce

Global AAAA DNS record for: *.domain.tld
Private resource for: test.domain.tld

Run resolvectl query test.domain.tld.

results:

A record pointing to 100.90.128.XXX (site subnet)
AAAA record pointing to global IPv6 of pangolin instance

Expected Behavior

Either:

No AAAA record gets returned
Pangolin adds support for IPv6 subnets and returns the according IPv6 for test.domain.tld
