Forwarding based on Client IPs

[Siju George]

Hi,

Currently I am using Bind9 for DNS.
I wish to do the following forward.

1. Forward to domain Name Servers based on client IPS.

    a. Forward one set of LAN users to OpenDNS DNS servers soo that I
can restrict them
    b. Forward a second set of LAN users to google DNS server
    c. Forward a third set of LAN users by default through OpenDNS
but for some domains through google DNS.

Could you please let me know if this is possible with Bind9 or any
other DNS server?

Thanks

Siju
