This got me more curious. So I did some checking to see if the percentage of IPv6 servers in a given country's NTP pool was larger or smaller than the percentage of IPv6-enabled users in that country (according to Google). My assumption is that if the amount of IPv6 servers in the country's pool is larger than the amount of IPv6 users in the country, it must surely be safe to return any AAAAs for that country's .pool.ntp.org. Turns out there's only one country that has a larger deployment of IPv6 users than IPv6 members in its pool.ntp.org, and that's Belgium. In be.pool.ntp.org there are 16 IPv4 servers and 5 IPv6 servers, so the latter constitute 23.81% of the total. The amount of IPv6-enabled users is greater: 30.28%.
