That’s… well, that’s just not how tcp/ip works. Your phone number has nothing to do with your device IP…
It does when your phone number is used for 2fa in a session running on tcp/ip
Phone numbers are available to many apps if they target older SDK versions and serve as an additional unique identifier.
