DNS will return all 3 IPs on a query, and it's left to the client side
which to use.  Most often the first one is used.  "Round robin" DNS
servers will alternate the order of the 3, but that still leaves a lot of
room for locking in on a single address by multiple clients.  You could
set up different names for the IPs and bind groups of Xymon clients to
each to spread out the load, I think.
