using alternate DNS resolvers - try dnsmasq

[John Gerth]

The Linux resolver is a global service and can't be configured
by interface or connection.

However depending on what you need you may be able
to get it from "dnsmasq".  This is a handy front-end to the resolver
functionality originally designed for home networks behind NAT firewalls.

Take a look at "dnsmasq -S ..." which lets you point specific domains
at different DNS servers, but you may have to looka at other options as
it sounds like you want to control reverse-lookups.
