Experimentally enabling IPv6

If you are following the pool mailing lists you'll have seen that the last days have carried a flurry of activity as new code for IPv6 support (and distributed monitoring) has been tested on the "beta pool" site.

June 8th is World IPv6 Day where many sites small and big will enable the IPv6 protocol for the day to help test everyones IPv6 readiness.

Here at the NTP pool we are today enabling monitoring of IPv6 servers; and over the next 12 hours we will start in a limited fashion to serve AAAA (IPv6) DNS records to clients asking for them. Right now the pool site is enjoying a brief break while the new code and database updates are being deployed.

For now this will only be on the "2.pool.ntp.org" zone; but unlike Google, Facebook and most other sites we are not planning to turn this off again on June 9th.
