+- supports DoH or DoT (We love DNSCrypt, but there is already https://github.com/DNSCrypt/dnscrypt-resolvers which is directly supported by dnscrypt-proxy, so we don't consider useful to list providers only supporting it).

+- doesn't log IP addresses during normal operation (If your suggestion logs, please compare its privacy policy with other servers on our table that keep logs).
