ISPs are a blackbox and it's not possible to figure out what they do from user-side. There is also hardly anything you can do about from your side. Using a vpn or similar solutions is only shifting the problem from one provider to another. You can reduce the exposure with some measurments, but they are also expensive and complicated. But for this (and other) reasons companies have started to fix it from the server-side by offering encrypted connections and working on ways to hide your trail from the middleman and their attatched agencies.
