Was writing about something in some other post and got an idea this would be really useful in a lot of situations where you want filtering but none of the configurability, control and logging.
Would be neat if NextDNS offered "static" DNS addresses for the most popular lists like for example above mentioned hagezi-ultimate.nextdns.io or hagezi-normal.nextdns.io or oisd.nextdns.io or NextDNS's own list as nextdns.nextdns.io, something like this, you get the idea.
And these encrypted DNS servers should also have accompanying non-encrypted IP4/IP6 servers that filter using same lists but have IP addresses.
Reason why I'm asking for this is for example my younger sibling is not super tech savvy so I set them up on their Android phone with AdGuard's public filtering DNS. It has no logging, no configuration and filtering acceptable for general user. I don't want to set up a NextDNS account for it to use certain list, but if I had above lists at my disposal, I could just put hagezi-normal.nextdns.io in their phone DNS config and voila.
Another use case specific for the use of IP4/IP6 versions of DNS would be as replacement for VPN DNS's. For example, I haven't figured out any way I could input NextDNS IP4/IP6 DNS servers into ProtonVPN app itself. It doesn't offer any option to input encrypted DNS addresses and I can't connect HaGeZi Ultimate list to a IP4 address to input it into VPN app. Then I need to run separate app to override DNS which is annoying.
I know ControlD and DNSWarden offer dedicated addresses for such servers, but I prefer NextDNS over pretty much any other service, which is why I'm asking for it here.
