Stubby Example:

dns_transport_list: [GETDNS_TRANSPORT_TLS]
tls_authentication: GETDNS_AUTHENTICATION_REQUIRED
listen_addresses:
  - 127.0.0.1@53
upstream_recursive_servers:
  - address_data: 80.211.208.74
    tls_auth_name: "dns.radeksprta.eu"
    tls_pubkey_pinset:
      - digest: "sha256"
        value: teXpPMydh/upfzX5W9tlx1RWxo649tAIMfVlAqzXPuE= 
idle_timeout: 60000 # keep-alive for 1 min, for better performance
limit_outstanding_queries: 10 # try to reduce SERVFAILS
timeout: 12000 # 12 sec, try to reduce SERVFAILS

Notes:

No logging means that I don't log dns queries but certain statistics such as the latency and query status are logged.
