ipv6-only hostname override ipv4-wildcard

  • 772

I have an ipv6-only host (accessible through a tunnel) and another host (webserver) with many subdomains on ipv4 and ipv6-wildcards

v6only.example.org AAAA 2001:DB8::1

*.example.org AAAA 2001:DB8::2
*.example.org A 203.0.113.2

How do I prevent v6only.example.org A to match the wildcard, resolving it to 203.0.113.2

  1. You don't. An explicit label (in this case v6only.example.org) will always be used in preference to a label generated from a wildcard. Just add an A record for the v6only.example.org name and it'll work as you want.
