Not necessarily - it depends on the clients.  With multiple A records, the
client doesn't get *an* IP address, it gets a list of them.  If it
randomly rotates the list before using it, then the load gets distributed.
This might be counterproductive if the DNS server is rearranging the order
based on actual load, but that's extremely unlikely.
