Anyone would care about it only when users from those addreses interact with whatever the software that ends up creating those databases. If those users never buy stuff from Amazon.com, Amazon.com does not care where they are. But eh moment they do, somewhere someone is cruniching the data that says "Of 10 sites that I saw this IP address access and provide a clearing for the credit card transaction, 9 ended up being within 3 miles radius of ZZZZ. Lets put a tag on that" > The neat thing about selling databases like that is nobody can ever prove how > incredibly inaccurate they are.

The really neat things about talking to computer geeks is that they all operate with the lots of absolutes. They will explain to you why in a specific case it does not work and forget that those specific cases are usually exceptions. ALex P.S. So, ever bought stuff from Amazon from one of those IP addresses and sent it to some non-related location *just* to confuse the mapping systems?
