I don't like PragerU, but really? My ISP has apparently IP-blocked their website.

It still shows the IP addresses for my manually-set DNS: DNS.watch. I checked on my laptop (which doesn't have it manually set), but it's Linux and I don't know how to find the DNS server IP there, so I just used whatsmydnsserver.com which lists 3 addresses: 1 from my ISP, then 2 from Google. I went back to my main computer and tested that website and it lists two: 1 from my ISP, then the primary server I manually set.

    I'm able to access it over my laptop with these settings, but not my Windows computer. Perhaps this has to do with how Linux and Windows handle DNS servers? Perhaps Windows is less secure, thus my ISP can view what's being requested?

      After talking with asterias, I was able to install a client to encrypt my DNS traffic, which allowed me access to every blocked website, including prageru.com. This reveals that this is not an IP-block, but rather much worse: my ISP has been looking at my unencrypted traffic.

      Thanks a lot, though, man!

        Tomorrow I'm planning to talk with them, so we'll see what happens. I don't want to go public with it, but I might have to if they don't cooperate.

          I tried this with different DNS servers (DNS.watch and Quad9) but they won't work on my laptop, which is odd since Google's DNS worked on it (though not on my Windows PC as I said earlier).

          Sorry for the spam but I did some more testing and while Google's DNS temporarily allowed my Linux Laptop access that is no longer the case.

          I've noticed that right after I restart my modem I'm able to access blocked websites for a very short period of time. So it probably has nothing to do with the OS or DNS server.

          Maybe your modem has been attacked through some vulnerability? Maybe its DNS settings have been hijacked? Can you login into its settings and see the DNS values?

          Concerning your ISP, maybe it's not some wrongdoing on their part but a case of hacking. Maybe you could ask at their technical support desk if there's something wrong with your modem.

          I checked their default DNS servers and they're both owned and operated by my ISP. Also: the issue persists when I use other DNS servers, even when I manually set them on my PC.
