of the TTL. However statistically each has an equal chance of using
each address. A test with one or a few clients won't show it especially
if they use the same dns server and start at the same time, but it does
work with large numbers of clients. Also if DNS returns multiple
addresses and the first choice does not respond, IE will move on to
the next in the list - other browsers may not do this as well.
