How To Install dnsproxy on Ubuntu 22.04
Introduction
In this tutorial we learn how to install dnsproxy
on Ubuntu 22.04.
What is dnsproxy
dnsproxy is:
dnsproxy forwards DNS 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.
Another possible scenario is a firewall where proxy queries should be forwarded to the real server in a DMZ.
