[[ sneck ]]
Comparing the database to the IP that our customers used to make purchases we exceed 95% accuracy in identifying the country, and 75-85% in city/state. The big exception is AOL, since their IP assignments are pretty well randomized with respect to geography.
*dynamically* randomized, no less, or so I've been told. As in: _all_ the customer session addresses are assigned out of *one* DHCP pool. I thought that 'unlikely', considering the mayhem on internal routing tables, but the AOL rep was rather insistant that that _was_ the case. They also have 'virtual' POPs, where they just backhaul ('tens if not hundreds' of miles, in same cases) voice, rather than having any physical equipment present.
