Subject: load balancer product for dns content switching
Spent quite a bit of time researching products out there looking for one
that will do content switching based on the domain being queried, and
I'm coming up empty.  Can anyone point me in a decent direction?

For example:

all requests are sent to one (HA) VIP, and then:

host.bob.domain.com gets routed to dns server group 1
host.bill.domain.com gets routed to dns server group 2
and so on...

Thanks for any advice
