    Yes! In fact ISPs can use fingerprinting techniques to match websites with known data transmission patterns (ping, badwidth, packet timing, etc) to guess what websites you might be accessing even through an encrypted vpn. Some vpns (like mullvad and probably others) will throw in false data packets to thwart this type of fingerprinting.

    Yeah, I remember some case where a college student was caught while using the school’s network because they new the times and filesizes of something. I don’t remember the exact details though.

      Yes, use any other DNS other than your provider. Adgaurd at minimum, PI hole with advanced lists is better. Both even better.

        I agree using something like Cloudflare or Quad9 is better then not using it at all, and making sure to turn on DNS over HTTPS is massive benefit. But as shown in my previous linked video even with this turned on a ISP can see/snoop DNS queries.

        A VPN would help obscure website you visit through the VPN, but your ISP would still see the connection to the VPN’s IP address.

        Though now comes the question of how much you trust that particular VPN.

    Yes. VPN still uses your data, more of it in fact because encrypted secure tunnel files are generally larger than the original data and also cached data on the ISP network are no longer called, so more goes to the greater internet.
