:ntpd uses host2sockaddr to get the first address returned by DNS and
does so only once.
:Since the first address is often an IPv4 address, this causes ntpd to
fail in IPv6 only environments.

Fix either your DNS (or your IPv4 routing) then.
If IPv4 doesn't work on your network, why do your DNS server
responds with such addresses? Fixing each and every app
to work around this is not feasible.
