One can geolocate well enough with many IP addresses that, with a bit of additional data if not solely using the IP address, the request source is quite identifiable. Even several years ago (i.e. in "less sophisticated" times), I had a few occasions to do this manually. The experience was eye-opening. (It's one thing to understand the concept. It's another to drill down and target someone in a matter of minutes, if not moments.)
