I noticed that Quad 9 is not able to respond to the spy.pet query:

$ dig spy.pet @9.9.9.9 +short
;; communications error to 9.9.9.9#53: timed out

But Cloudflare DNS is able to do it:

$ dig spy.pet @1.1.1.1 +short
104.26.0.165
104.26.1.165
172.67.74.73

And to be sure, I checked another domain with the same TLD to rule out the option that Quad9 is unable to handle the .pet TLD, but I received a correct answer…

$ dig hello.pet @9.9.9.9 +short
3.64.163.50

Does Quad9 censor DNS queries?

      Don’t all providers have the ability to filter things?

      It depends on what you can consider “the ability”. If by ability you mean have to deploy a team of engineers working for a week to make it happens, that’s okay, if they’ve their system built for it things are different.

          I can do this in like 5 seconds with my PiHole and not only am I not a network engineer,

          Exactly and consider Cloudflare for instance, adding an “if domain block” is easy but then once you’ve thousands of servers running the same piece of software across the globe deploying updates and features becomes way slower and way harder. You’ve to consider tests, regressions, a way to properly store and sincronize the blocklists across nodes etc…

          I’m not saying it can be done, because it can. But it will take longer and it will be a problem for someone. Besides you only have that point and click interface in your PiHole that allows you to do it in .02 because someone spend a few hours developing the feature. :)
