My network is optimized for HTTP so i'd only be wanting to provide DoH. But I think blocky can serve a zone file and disable resolution otherwise.
Now my concern has been with offering like a whole ass DNS service, not just a single zone. I can see like 50 req/s just on my own network when loading up a single nostr client, nostr users would pummel our servers. Im not sure I want to be responsible for resolution of the entire world, and forwarding that traffic to free providers probably is a quick way to get blocked, so probably need a paid upstream or something.
Anyway, if we could contribute with a single zone for clients id have it up yesterday. Most things only accept a single DoH endpoint, not even secondary, and most primary/secondary handoffs are just complete failover so... idk how to solve that problem
