If Mozilla silently enabled DOH-via-CloudFlare for you, it would show up here right? Because if yes, this would make it quite easy to find whether you have the right settings without having to find it somewhere in a configuration screen or trying to find out which users' throats Mozilla ended up deciding to force this down.

Sort of: it doesn't differentiate between DoH and normal resolution (it only does IPv4 TCP & UDP resolution). This means that it will return Cloudflare (i.e. ASN of CLOUDFLARENET), but probably the same Cloudflare as if you are using Cloudflare's public DNS servers.

Tip: You can check a specific DNS server with dig and curl:

  UUID=$(uuidgen)
  dig ${UUID}.which.nameserve.rs @1.1.1.1
  curl --silent https://which.nameserve.rs/debug.txt | grep ${UUID}
and then do a ASN lookup on the IP address

Note: the debug page is unofficial, and may change, so don't bake this into anything.

Neat, this helped me realize I haven't switched away from my provider's default DNS when I moved in, which is something I usually do.

How to choose a DNS server? I usually just go with 8.8.8.8/8.8.4.4, I used to always test this with Namebench (https://en.wikipedia.org/wiki/Namebench) and these always turned out as the fastest - but it looks like it hasn't been updated since 2010 - are there any better tools for this, or any considerations in general? I prefer performance over privacy here, I think privacy should be on a different layer.

This is really cool, especially because I can just 'wget -qO- $RANDOM.which.nameserve.rs/api.json?callback=myfunction' which means I can use this in scripts. (For example an added field to scripts that grab from ifconfig.co)

Thanks, I use it like this for some of my pages.

But please, only light, non-commercial use! It is on the cheapest static IP that I could find with no failover or anything.

It is really easy to run your own copy if you need it for a commercial project.

Doesn't show IPv6 for me.

I always use IPleak.net [1]. Works for public IPv4, IPv6, DNS server, Tor/AirVPN exit node, BitTorrent, geolocation, and all kind of browser metadata.

Browsing through comments shows this can do some things IPleak.net can't do such using wget/curl with API.

Someone else in this thread suggested GRC's benchmark utility [1]. It sounds pretty comprehensive, but I haven't tried it yet.

Duly noted. It's ok, most of my scripts just pile up the cobwebs and never get used anyway, and they are all personal, not commercial. I would of course consider standing up my own for any real use. Good work!

Now you have me thinking about the economics of api as a service... another rabbit hole.
