Experimental DNS Privacy Recursive Servers

The following servers are configured to support TLS on port 853 for testing purposes.

Note that they are experimental offerings with no guarantees on the lifetime of the service, service level provided. The level of logging may also vary (see the individual websites where available) - the information here about logging has not been verified.

Also note that the single SPKI pins published here for many of these servers are subject to change (e.g on Certificate renewal) and should be used with care!!

Live monitoring of these servers can be found on the Test Server Monitoring page

A YAML configuration file for Stubby containing a the details of these servers is provided with Stubby and can be found here. This file enables only the subset of servers operated by the stubby/getdns developers by default, users can choose to enable any of the other servers by uncommenting the relevant section.

Note that the Yeti servers use a different root key for DNSSEC! See the Yeti project for more details

See https://dns.cmrg.net/ 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.

Has some issues with DNSSEC responses - this is under investigation.

Yes, logging at stunnelstunnel 4 + BIND

See https://ldn-fai.net/serveur-dns-recursif-ouvert/
The host name is ns0.ldn-fai.net however a self-signed certificate with common name of the IP address is used, so SPKI pinning is recommended.

See OARC website 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.

(1) Since the nameserver is behind a proxy the client IP is not logged inside the nameserver

    Lorraine Data Network servers are also available on port 443, and they provide a certificate on the linked webpage from which you can derive the SPKI pin.

    1. Not all entries have the same color, can the styles be reseted?
    2. Is it possible to update the example stubby.yml file with the new servers?
    3. Should we create an more experimental list at the end and put the OARC DNS Privacy Server in there because no strict privacy supported?

    Wow, great! The following links should be corrected or removed. The JSON-Variant of the config should be updated or removed.

    A configuration file for Stubby containing a subset of these servers which can all be validated can be found here.

    A JSON file with the details of the same subset of servers can be downloaded here.

    Still one death link: "The following are currently in the default Stubby config file mainly because they have been around longest and are the most stable."

    All adressed: You can now remove the last 4 comment from me

    1. Thanks for all the suggestions! I plan to add a yml and JSON file with the full set of servers to this page too. 

      LDN server was just added to the monitoring too.

    All entrys for IPv4 servers, except the logging ones, for use in the yml config file (110317): https://pastebin.com/Wd45uhXu

  7. Thanks - we already have a PR https://github.com/getdnsapi/stubby/pull/41 to add the servers to the .yml file so users can choose which ones to enable. Should be in the next release of Stubby.

    Wow thanks for all fixes...

    Some small cosmetic bugs:

    • the order of the list on the Wiki is not the same than the yaml file
    • the UncensoredDNS server is not enabled in the yaml
