Public resolvers

Tip
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

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.

Warning
Note that they are experimental offerings (mainly by individuals/small organisations) with no guarantees on the lifetime of the service or , 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).
