It's their end
The domain is v6ns.org, and the record I am attempting to query for is
ns1.v6ns.org - here's what the Kloth Dig tool gets:
v6ns.org. 86400 IN NS ns1.v6ns.org.
v6ns.org. 86400 IN NS ns2.v6ns.org.
;; Received 150 bytes from 199.249.112.1#53(A2.ORG.AFILIAS-NST.INFO)
in 4 ms
If I retry this DNS-query, I get:

Which seems perfectly valid for a v4&v6 delegation.
I set the domain up to experiment with IPv6, which could be why I've
got a
problem...
Shouldn't, but might... I'm running a v4-v6 DNS right now and I've
been through some trouble to get it working...
I have a single DNS server with a IPv4 address and two IPv6
addresses. The
zone file is as follows:
$ORIGIN v6ns.org.
$TTL 300
@ IN SOA ns1.v6ns.org. dns.newtonnet.co.uk. (
2010012000 ; Serial
14400 ; Refresh
7200 ; Retry
950400 ; Expire
300 ) ; Negative Cache TTL
IN NS ns1.v6ns.org.
IN NS ns2.v6ns.org.
ns1 IN AAAA 2a01:348:133::a1
ns1 IN A 77.103.161.36
ns2 IN AAAA 2a01:348:6:a1::2
This is NOT how it's configured in the Glue:
ns1.v6ns.org. 86400 IN A 77.103.161.36
ns2.v6ns.org. 86400 IN A 77.103.161.36
ns1.v6ns.org. 86400 IN AAAA 2a01:348:133::a1
ns2.v6ns.org. 86400 IN AAAA 2a01:348:6:a1::2
Local lookups for ns1.v6ns.org (A and AAAA records) work fine, as they
also do from Men&Mice's online Dig tool. So why not Kloth's?
Possibly because it's broken. It works fine here; results conform to
the zone you listed above.
I can't help but feel it is given the lack of an IPv4 A record for
ns2.v6ns.org - either as glue in .org or within my own v6ns.org
zone. But
should this matter? In the absence of an IPv4 A-record for the
ns2.v6ns.org delegation in .org shouldn't their Dig attempt to
connect to
ns1.v6ns.org instead (yes, they are the same machine but noone else
knows
this but me... and you!)?
I'm not a DNS expert, but I think it should. However, currently there
IS a A-glue for ns2
