Good idea. Yes, the DNS resolution in ntpd is really, really stupid. I
always specify addresses in ntp.conf for this reason and the fact that
it there are multiple addresses only the first returned will be
tried. It never fails over if that one is dead. (And, should an IPv6
address be available on a system that does not have IPv6
connectivity...).
