dnscrypt-resolvers VS SimpleDnsCrypt

Block the google, cloudflare ones - will cover most situations. Or white-list egress IPs for your unknown devices if you have to use them. Or setup a transparent proxy and inspect the content there and deny DNS. There ARE ways but yes things get a bit more complex. Most firewalls will be happy to index a long list of IPs as a set and perform well checking if src/dst ip matches. So you can use sites like https://github.com/dnscrypt/dnscrypt-resolvers to extract the list of IPs and update the set.

Since they don't seem to be mentioned on their website, DNS Stamps are sdns://AgMAAAAAAAAAACCaOjT3J965vKUQA9nOnDn48n3ZxSQpAcK6saROY1oCGQdkbnMwLmV1Ci9kbnMtcXVlcnk ("zero" version) and sdns://AgMAAAAAAAAAACCaOjT3J965vKUQA9nOnDn48n3ZxSQpAcK6saROY1oCGQxraWRzLmRuczAuZXUKL2Rucy1xdWVyeQ ("kids" version).

But these are already present in the list of public encrypted resolvers (https://github.com/DNSCrypt/dnscrypt-resolvers/blob/master/v...).

I had some spare time over the holiday period so I created a site that displays current information about the responses from the DNS servers listed in the public-resolvers.md file (https://github.com/DNSCrypt/dnscrypt-resolvers/blob/master/v3/public-resolvers.md) and makes the latest results available. Have a look at https://status.ednst.com/index.html for details on how to use the site.

For servers using encryption, there are the most up-to-date lists: https://github.com/dnscrypt/dnscrypt-resolvers
