I cheat the other way by letting the nameserver see the AAAA's for the root servers that have IPv6 addresses.
e.g. zone "f.root-servers.net" { type master; file "master/f.root-servers.net"; notify no; allow-query { localhost; }; }; master/f.root-servers.net: @ 3600 IN SOA drugs.dv.isc.org. marka.isc.org. 1 3600 1200 604800 3600 @ 3600 IN NS drugs.dv.isc.org. @ 3600 IN A 192.5.5.241 @ 3600 IN AAAA 2001:500::1035 The question is what do we wish to test. A IPv6 only world or a IPv6 only network with access to proxies etc. to allow access to IPv4 resources indirectly.
