Hello Selfhosted community!

I know not many folks actually host their own DNS, but for those that do: do you use any hosted secondary DNS servers? Meaning delegating slave servers.

What features would you be looking at in such a service?

Reason asking: I am looking to build a free service that would allow users to register their zone , choose geographic location and our servers will do the secondary part for it. Though limited on a free tier - say 1-3 zones (domains).

It will include a management panel.

Edit: Currently the Name Servers do support DNS over TLS/QUIC/HTTPS.
