Configuration
The configuration is not a simple thing for everything or everyone. It depends on the device, operating system or software.
DoH for example can be used in Browsers directly.
Routers typically offer DoT as a secure alternative to Do53 (plain).
If you run a local resolver, then the best thing is to run something like DNSCrypt or RouteDNS. These resolvers support many, if not all, of the secure DNS protocols.
In such a local resolver, you can configure the LoopX DNS servers.
There will be a dedicated Configuration section to provide some examples and details for various dns resolvers.
