DNS infrastructure is very simple - just a single authoritative DNS server without an recursor (since we only care only the zones on this net, without needing to access any other zones)
The DNS server used is Knot DNS running in Docker container with persistant volumes.

Test by running dig @127.0.0.1 test.cb TXT. To run on local machine, you will probably have to switch the port (e.g. 5300), and then use dig @127.0.0.1 -p5300
