Background
The following servers are configured to support TLS on port 853 for testing purposesare 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, 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 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
