Depending on your location it can actually be geolocated into your specific city block, I geolocated an online friend’s IP just for the hell of it (I already knew where they lived) and it spit back out the city block they lived in as well as a lot of other very identifiable information

Also, if you can ping devices on that network using that IP you can also use that as a way to easily identify users. That’s if they have anything that isn’t firewalled, obviously, but the point stands!

This could also be the alternate plot to Iron Lung
