On the systems where your full-function resolvers are running,
it makes good sense to include 127.0.0.1 in the host system's
resolver configuration so that other applications running on
the same host have access to the local name server.
On the systems where authoritative name servers are running,
this approach is usually not such a good idea, as these name
servers are likely to have recursion disabled, and so won't
be able (as a matter of policy and configuration) to resolve
general DNS queries. The host system's resolver configuration
should refer to the full-function resolvers which serve the
