      Hi,

      Running Unbound recursively, however aaaa.v6ns.test-ipv6.com wont resolve, for example:

      [2.7.2-RELEASE][admin@pfSense.lan]/root: dig -6 aaaa aaaa.v6ns.test-ipv6.com

;; global options: +cmd
;; Got answer:

      Yet using Google's DNS it will.

      [2.7.2-RELEASE][admin@pfSense.lan]/root: dig -6 aaaa aaaa.v6ns.test-ipv6.com @2001:4860:4860::8888

      Any tips on where to begin chasing this down?

      Oddly the AAAA record is buried in a trace:

      [2.7.2-RELEASE][admin@pfSense.lan]/root: dig -6 aaaa aaaa.v6ns.test-ipv6.com +trace | grep AAAA
aaaa.v6ns.test-ipv6.com. 300    IN      AAAA    2001:470:1:18::115

        @chill_out said in ipv6 test AAAA DNS queries not resolving:

        aaaa.v6ns.test-ipv6.com

        dig you do a trace.. I show its now working and sends back SOA...

        aaaa.v6ns.test-ipv6.com. 300    IN      NS      v6ns.test-ipv6.com.
aaaa.v6ns.test-ipv6.com. 300    IN      NS      v6ns1.test-ipv6.com.

        Where did you find that FQDN? And what it suppose to only resolve via IPv6?

          @johnpoz yes it's only supposed to resolve if one is using ipv6 (it comes from a test site of the same name).

          So dig can resolve it, but unbound cannot.

            @chill_out that is odd, since as you see from snip of my trace I was talking to the ns via IPv6..

              @johnpoz interesting, your extract was from the unbound logs?

                @chill_out that was from a trace with dig..

                So tried it again, and while still having an issue to that v6ns, I do get answer from the v6ns1

                Here trace on pfsense.

                So if I trace it, you would think normal query would work.. But I just keep getting servfail..

                AHHHH!!!! I found my problem.. Maybe yours is sim?? On my outgoing interfaces for unbound, I only had loopback, it was never talking anything via IPv6 when you asked it.. I added my HE tunnel interface as an outgoing interface.. And now I can resolve it

                  @johnpoz yes, same issue! I changed outgoing interfaces to "all" and now it can resolve.

                  Thanks for the tip!

                    @chill_out Personally I normally just have it use loopback.. And I am back to that - I don't really need my dns going out my HE tunnel..And other than that test of theirs have no need of it.
