Round-robin means that each time the server is asked for the A records, it
returns them in a different order.  Clients usually connect to the first
address in the address list that was returned to them.  Since the
reordering will result in the first entry rotating among all the possible
entries, and this should result in pretty even load balancing over long
periods of time.
