Cant believe law enforcement is using this kind of info to execute searches. Wouldnt that undermine the credibility of any evidence brought up in trials for any geoip locates? Seems to me locating unknowns somewhere in the middle of a big lake or park in the center of the country might be a better idea....how about actually marking an unknown as...oh, I dunno: "unknown"? Is there no analogue in the GeoIP lookups for a 404?
It's not unknown - it's (according to the DB, anyway, which has a bunch of flaws) "in the US somewhere". The problem with MaxMind (and other geoip databases I've seen that do Lat/Long as well as Country / State / Town) is that the data doesn't include uncertainty, so it returns "38.0/-97.0" rather than "somewhere in a 3000 mile radius circle centered on 38.0/-97.0". Someone should show them RFC 1876 as an example of better practice. Cheers, Steve
