Me too; according to Google's data, IPv6 end-user deployment in .au is just at 1.20% and in .nz 0.88%. So the IPv6 load ought to be miniscule. http://www.google.com/intl/en/ipv6/statistics.html#tab=per-country-ipv6-adoption It would appear that the country-specific "2" hostnames do work as expected already, for example "2.az.pool.ntp.org" returns no AAAAs because there is apparently no IPv6-enabled servers in Azerbaijan. In Portugal, on the other hand, there is only 1 IPv6-enabled server in the pool, which *is* returned by "2.pt.pool.ntp.org". So I guess that the concern isn't with the absolute number of IPv6 servers available in a given region, but rather the ratio between IPv4 and IPv6 servers? If so, one possible solution could perhaps be that it could be made so that AAAAs for a region-specific hostname would be returned IFF the number of IPv6-enabled servers wasn't too low compared to IPv4? I tried to find such examples of countries with few IPv6 servers compared to IPv4; the worst example I've seen so far is Portugal with a single IPv6 server and 8 IPv4 ones.
