How to avoid censorship at the DNS level?

Tor provides a built-in DNS forwarder.

This is a minimal Docker container that uses a local caching DNS server (dnsmasq) which will compensate for TorDNS being a little slower than traditional DNS servers.

Usage

Build it using:

docker build --pull --rm -f Dockerfile -t anarres:latest .

Run it using:

docker run --rm -d -p 53:53/udp anarres:latest

Test it using:

dig @127.0.0.1 cr.yp.to

Expected output:

; <<>> DiG 9.11.5-P4-5.1+deb10u6-Debian <<>> @127.0.0.1 cr.yp.to
