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.
Background
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!!
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).
**Note that the Yeti servers use a different root key for DNSSEC! See the Yeti project for more details
Test servers
Default servers in the Stubby config file (run by the Stubby developers)

|---|---|---|---|---|---|---|---|---|
| 1) The following are currently enabled in the default Stubby config file because they are run by the stubby/getdns developers and have no known issues. | ||||||||
