Hello Barry,

I'm sandip's friend and we are working with this for last few weeks.yup
we want to
only 10 IP's in a random order at a time.I'm not going to restrict it
in
10 IPs.from anywhere if u request for www.mydomain.com or if u do
dig www.mydomain.com u'll get different set of 10 IP's in a RR order.

the usefulness is that if any user req for www.mydomain.com he will get
response
from one of that 10 IPs not from one of 55 IP pools.

Any idea how to do that ?

thanx.
