OK, point.  I certainly have IPv6 addresses on my home network, thanks to an
Internode tunnel.  However, since its tunnelled, maybe that changed things.
Certainly at the moment both my internal DNS proxy (my pfSense firewall) and
resolv.internode.on.net are IPv4 addresses.

*shrugs* I'm willing to hear different about my results, though...
