Forwarding DNS queries based on the source IP and/or MAC of the requesting client

How would one configure BIND on a Linux system to forward DNS queries to a different upstream forwarder, based upon the source IP and/or MAC of the requesting host?

For example, I might want to send DNS queries from certain hosts on my network to OpenDNS, others to Google, and all others to my ISP.

Hi,

You can do different treatments according to source IP using views in bind configuration.

For the MAC? I've never seen neither heard of, and I doubt it exists in bind.

Sorry, I should have been more clear. I didn't mean for the "Mac", I meant the MAC which is the hardware address of the network card

Wonder if using a static arp entry and then use the IP you set to that mac address would work?

Many thanks, BIND "views" are exactly what I needed
