Hmm, when we set up the round-robin entries

wacluster IN A 216.125.123.67


it would return multiple values:

But woudn't that just be different addresses handed out to separate
requests? So, one person would get .66 and the next .67.


Actually, everyone gets both; the device picks which one to use, which is what
allows it to randomly balance or fail over to the other address if the one it
picks isn't responding. (Mind you, it's not perfect, since a 404 or 500 error
is still "responding," which is why a real load balancer is better.)

If you want to give it a shot, do an nslookup for that host address
(wacluster.millikin.edu) and it should give you both addresses.
