Is there a way (or is it planned) to use nextnds.io, zero.dns0.eu and dns0.eu at the same time?
At the moment, I use quad9 and dns0.eu:
Pi-hole v6 allows you to specify any number of upstream servers.
But I'm not sure why one wants to have more than 2 upstream servers …
Thank you very much, that answers my question.
I want to try nextdns together with dns0.
(Sometimes I guess, dns0 is not constantly reachable, but I haven't tested it.)
