services.doh-server.settings.upstream

Upstream DNS resolver. If multiple servers are specified, a random one will be chosen each time. You can use "udp", "tcp" or "tcp-tls" for the type prefix. For "udp", UDP will first be used, and switch to TCP when the server asks to or the response is too large. For "tcp", only TCP will be used. For "tcp-tls", DNS-over-TLS (RFC 7858) will be used to secure the upstream connection.
