I don't think ntpd has an option yet to autoreplace bad servers from
DNS pools via future DNS queries. Either way all that's really
needed is 2+1 to break ties, plus 1 or 2 for redundancy.

This will tell you status of peers.

You'd have to first figure out why it didn't work out of the box.

The order doesn't matter. Though if DNS is not up before
ntpd on boot, specified poolnames won't resolve and I think it's still a
oneshot so only servers listed by ip would be loaded. see ntpq -np
while listing a bogus hostname, a poolname, and an ip.
