## How to avoid censorship at the DNS level?

[**Tor**](https://www.torproject.org/) provides a built-in **DNS forwarder**.

This is a minimal **Docker** container that uses a local caching DNS server ([**dnsmasq**](https://dnsmasq.org)) 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
