I use 126.96.36.199 with DNS over TLS, in various different setups, configured directly in the routers themselves (all running ASUS-Merlin)
I know I can use a Browser from desktop clients that are connected to a given router, and then access the help page: http://188.8.131.52/help
… that will tell whether DoT is in use, this works fine.
However, in some setups, I only have (headless) servers as hosts, that are not running any desktop environment, hence I can’t run a browser to check if the DNS setup is using DoT. I can issue “curl” commands from those hosts though.
Is there any curl-friendly cloudflare Test / Help URL that I can use to quickly check whether the hosts name resolution requests are being properly routed to cloudflare via DoT? Like a json API endpoint that would give the same output that 184.108.40.206/help produces? Currently, pointing curl to 220.127.116.11/help directly (allowing curl to follow redirection) prints the page HTML but without the test results, so it’s not useful
