DNS abstraction

[SuperSandro2000]

@astro had the idea that we could provide an abstraction around https://git.dn42.dev/dn42/registry/src/branch/master/data/dns to provide an easy way to deploy an recursive DNS server not relying on the sometimes flaky and ipv6 only servers advertised at https://dn42.eu/services/DNS
Topics that need to be solved:

• how to collect and process the data
• serve that data (TBD how)

Also we should abstract https://gitea.c3d2.de/zentralwerk/network/src/branch/master/nix/nixos-module/container/dnscache.nix#L39-L44 into that and move it out of the zentralwerk network repo https://gitea.c3d2.de/zentralwerk/network/src/branch/master/nix/nixos-module/container/dnscache.nix#L39-L44

You mean put every domain in kresd? Or deploy a knot which serves the dn42 zone? Do you know how such an amount of zones would scale with kresd?

Or provide abstractions to deploy one node in the any cast DNS network of dn42?

The dn42 zones defined in that directory. I am not sure which one is the best option, we need to determine that.

Do you know how such an amount of zones would scale with kresd?

No idea, there are not limitations written onhttps://knot-resolver.readthedocs.io/en/stable/config-network-forwarding.html

Or provide abstractions to deploy one node in the any cast DNS network of dn42?

I wasn't aware of that. That would maybe also be a good additional option.

Our main goal was to provide stable DNS for dn42 at the hackspace.
