A caveat: You should probably avoid using the default OpenDNS servers with dnscrypt-proxy.
From the 'Bad Relays' wiki page https://trac.torproject.org/projects/tor/wiki/doc/badRelays
"The most common misconfiguration I have seen is using
âOpenDNS
as a host's nameserver with what I think is the OpenDNS default config.
Services such as OpenDNS lie to you, under the name of protecting you.
The result is for instance getting redirected to their webpage when you
want to visit evil sites such as
âhttps://www.torproject.org/."
