Public resolvers

Public Resolvers: Several large organisations have announce DNS Privacy Servers - see DNS Privacy Public Resolvers
  • Quad9 (9.9.9.9) and Cloudflare (1.1.1.1) offer DNS-over-TLS on port 853
  • DOH servers are also currently listed on that page

Experimental DNS Privacy Recursive Servers

DoH servers

These are currently listed on the DNS Privacy Public Resolvers page and also the list maintained on the curl wiki. For any servers below with the note 'also does DoH' check these pages or the website of the service for the DoH endpoint.

DoT servers

The following servers are experimental DNS-over-TLS servers.

Note that they are experimental offerings (mainly by individuals/small organisations) 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!!
Oct 2020: The list below has been updated to retain only those servers that appear to still be actively maintained

Stubby

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 (occasionally the file lags this page).

    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. Sara Dickinson

      Thanks - updated!

  2. Anonymous

    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?

  3. Anonymous

    Lorraine Data Network server is not enabled in monitoring

  4. Anonymous

    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.

  5. Anonymous

    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. Sara Dickinson

      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. 

  6. Anonymous

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

  7. Sara Dickinson

    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.

  8. Anonymous

    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

  9. Anonymous

    The recently released knot-resolver 1.5.1 fixes some stability issues, please update and check if the issue still exist

    1. John Dickinson

      It doesn't fix them all unfortunately. We are working with the developers to get this fixed.

  10. Anonymous

    Getting "Server Not Found" for some domains in Firefox when using Stubby. Same domains work fine when using Google or OpenDNS servers.

    Do any of the test servers have issue trackers?

  11. Sara Dickinson

    It is more likely a problem with Stubby - do you have any logs from stubby? If so please open an issue here for us to help you debug:

    https://github.com/getdnsapi/stubby/issues

    Please let us know what OS you are using too. 

  12. Anonymous

    No. I'll enable logging and create an issue when I have the problem again.

    Hi Sara,

    It appears quad9 has officially announced support for DNS over TLS.

    https://www.quad9.net/faq/#Does_Quad9_support_DNS_over_TLS


    1. Sara Dickinson

      Woop! Thanks (smile)

  14. David Mora

    Hello -

    It appears Cloudflare has officially announced a DNS resolver service. Interestingly enough, they support both DNS-Over-TLS and DNS-Over-HTTPS. For DNS-Over-TLS they specifically state they support TLS 1.2 and 1.3.


    From some tests I have performed, it appears to be pretty quick.


    https://1.1.1.1/

    https://developers.cloudflare.com/1.1.1.1/dns-over-https/

    https://developers.cloudflare.com/1.1.1.1/dns-over-tls/

    1. bagio

      how to add on stubby.yaml i try something like this but fail ?

      here1

      here2


      edited: just delete the pinset and change transport from TLS to TCP and just work

      1. David Mora

        You should be able to use the transport TLS. I have something like this in my config:

        #Cloudflare
          - address_data: 1.1.1.1
            tls_auth_name: "cloudflare-dns.com"


        I think their doc might need a slight bit of clarification - they mention "dns.cloudflare.com" but if you check the example output they use "tls-host=cloudflare-dns.com"


        1. bagio

          yes the problem is on their cloudflare doc I just replace dns.cloudflare.com to cloudflare-dns.com work with pinset and TLS transport

          1. James Bond

            DOES NOT WORK ON MY END

                Could not schedule query: None of the configured upstreams could be used to send queries on the specified transports


                P.S.
                Other TLS resolvers such as unicast.censurfridns.dk work fine.
                Also, Cloudlflare’s DoH server works, so there are no issues with connectivity per se.

                1. bagio

                  I dont know what your problem but my config just something like

                  config

                  log

                  and just work


                  1. James Bond

                    Tried your settings, but it does not work on my end.

                    I put stubby.exe and stubby.yml into archive for you to examine, could you try it?

                    1. bagio

                      look like your config is broke

                      try to reinstall stuby

                      this my config from my raspbian I dont have ipv6 network so I leave ipv6 server resolver

                      if you want use my config that only need is just edit listen address then replace default stubby config

                      reference to edit

                      https://github.com/getdnsapi/stubby/blob/develop/stubby.yml.example


                      You need to be careful around whitespaces in yaml file, it's sensitive to it


                      edited wrong upload : https://transfer.sh/N5TkP/stubby.yml

                      1. James Bond

                        After trimming #commented parts and changing listen address, our configs appear to be identical, even whitespaces match. Alas, your config doesn’t work either. Hmm, perhaps Stubby’s for Raspberry works somehow differently than Stubby 0.0.2 for Windows 7 does…

                        Also, be aware that your config specifies port 5053 on a separate line which goes against the reference (I quote: “Use <IP_address>@<port> to specify a different port”).


                        1. bagio

                          that strange my stubby windows runing fine

                          stubbywindows

                          this my config stubby windows

                          https://transfer.sh/v8av8/stubby.yml

                          just paste my config to folder stubby and change dns on dhcp windows to 127.0.1.1

                          1. James Bond

                            Thanks for your diligent efforts, but it still does not work (downloaded the very YML and changed DHCP exactly to 127.0.1.1), log contains the same errors as before, Apprarently, I am not alone, check Github!

                            1. bagio

                              maybe Sara Dickinson can help or correct me if I wrong

    HI Sara,

    Can you help to advise how do I configure Adguard DNS in stubby.  Attach link https://adguard.com/en/blog/adguard-dns-announcement/ for your information. I cannot get stubby to use the adguard dns. Please assist
