Note that on port 443 this server can serve both HTTP 1.1 traffic (to securely access the nameserver credentials) on TLS connections and DNS-over-TLS on separate TLS connections due to some nifty, experimental demultiplexing of traffic, described here. So if port 853 may be blocked then this is a good option.

NOTE: As of June 2017 this server does not support Strict Mode because it does not offer the correct cipher suites to match RFC7525 recommendations.
