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

While still in pre-production state, you might want to look at:

F5 Big-IP? Pricey but it should do what you are looking for.


Citrix Netscaler as well.

A10Networks should be able to do what you are looking for.
