Quad9 Protocol Test Now Available - proto.on.quad9.net​

You can now test on which protocol Quad9 received a DNS query. This is especially relevant after configuring encrypted DNS in a router, DNS forwarder, system settings, etc, where previously, the only way to confirm which protocol was being used was taking a packet capture on the device which was encrypting the DNS traffic. More information here:

Yes, there are plans to add this information to the on.quad9.net page in the near future.
Any questions, issues, etc, please contact

Examples:

(This assumes the DNS settings on the system/network are set to use Quad9. The +https and +tls flags in these examples are used only to demonstrate the possible responses.)
