Right, how often does our external IP change on our home WiFi network or work WiFi network? There are so many other things that can be used to fingerprint. This is part of the reason encrypted DNS and other efforts have some merit. The cell providers have data and know exactly where you are via triangulation.

Has anyone been using Cloudflare's Warp VPN? I wonder if this is the best approach. Paying a private company to act as a one hop TOR to minimize fingerprinting. If the cell networks just see all CF traffic, they may know where I am but not who I'm connecting too. I get that this means I must trust CF but I trust them more than ATT/Verizon anyway. I just want some open source from CF on the mobile side that shows that the private keys are kept in the device's SecureEnclave and not anywhere on disk.
