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 or service level provided.
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!!

So if port 853 may be blocked then this is a good option. | |
