If anyone wants a redundant system and is happy not to self-host, then I can recommend NextDNS.

Works great, but not free over a certain number of requests.

Can’t speak to its privacy levels though - as with anything, assume records will be supplied to authorities when required.

But overall it has been great - provides network wide DNS filtering and has clients for mobile and desktop devices!

With a good dashboard, reporting and setting too.

Cost is minimal and I’ve been happy to pay for it.

A local PiHole is probably faster, but NDNS is set and forget.
