Last weekend I decided to give NextDNS another chance, you know, to see if the speeds were still as slow as I remembered. :)

Maybe it is because I have a new PC, but it feels faster so far then it first felt. Any way I checked dnscheck.tools website if the connection was good. And for the most part it shows that it is good ... however there are moments when I checked that I saw all of this?

I could be wrong, but for something that should connect to the closest servers from where I live, should not connect to many of those. But this is not the only DNS service that does this. I switched back to dns0.EU to see if it would happen there as well. Well, it connected to the right servers, but it also seems to connect to a Google server in Washington DC. And Cloudflare did not show anything strange, but it is US owned so it can look around with you anyway.

But dns0.EU is from Europe so why the F does it need to connect to a Google server in Washington DC, and why does NextDNS have moments where it connects to so many different servers worldwide?

Well I tried what Smoke mentioned, but if I refresh the page on dnscheck.tools then I get all of those servers again. Guess I can go back to Cloudflare, at least there it only goes through Cloudflare servers only. Guess I will be checking a few DNS providers in the coming days.

Could there be something wrong with the testing site? dnsleak test is a long-known reliable site for checking DNS leaks. Even Extended test here is only showing AdGuard DNS for me. Cloudflare, Google are not present here.
Same is true for:
Maybe something is wrong with dnscheck.tools's testing server.

Well, DNS Leak only shows one or two connections, so in this case the question is … which one is correct?
Both are correct. I asked adguard once about those connections and they said it is because they use 3rd party servers, since they can not afford their own like google or cloudflare.
So, you are basically using google servers or whatever company it belongs to, but DNS queries are routed, rebind or whatever the correct terminology is, to use NextDNS's template.
I believe dnschecktools goes beyond DNS and it shows the parent server's location, due to the limited IPv4 pool. Like when you set 8.8.8.8, it actually uses different IPs over the world.
