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.
