I found this was returning localised results from the other side of the planet, so I kept connecting to slow servers when more local ones were available. I ended up rolling my own from home. The only problem is there’s no way to do access control so I just have to hope not too many find it.
I didn’t open port 53. It’s DoT.
Even then, it took some extra effort to ensure it didn’t return internal network addresses from the outside.
