Hi Kevin - we have a dedicated dnsdist list, but I think we can spare one
reply here.

You could achieve this easily with a wilcard record on your auth server,
perhaps that is easier?

If that is not possible, you could try something like:

https://dnsdist.org/rules-actions.html?highlight=responseaction#addResponseAction

addResponseAction(RCodeRule(dnsdist.NXDOMAIN), SpoofAction("1.2.3.4", "::1"))

I have not tried this and it may not work - SpoofAction might in fact only
work when it receives queries. Can you try and let us know? (on the dnsdist
list).

Thanks!
