Description:

The dnsproxy daemon is a proxy for DNS queries. It forwards these
queries to two previously configured nameservers: one for
authoritative queries and another for recursive queries. The
received answers are sent back to the client unchanged. No local
caching is done.

Primary motivation for this project was the need to replace Bind
servers with djbdns in an ISP environment. These servers get
recursive queries from customers and authoritative queries from
outside at the same IP address. Now it is possible to run dnscache
and tinydns on the same machine with queries dispatched by
dnsproxy.

Other scenarios are firewalls where you want to proxy queries to
the real servers in your DMZ. Or internal nameservers behind
firewalls, or...
