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.
This will also depend on whether the xymon client resolves the ip once at startup or on each data send. If it's once at startup, then whatever ip it is given (even from a round-robin dns server) will persist until it is restarted. I'll leave it to those who have examined this behavior and xymon client internals to say which is the case.
