Geo location to IP mapping

    Yeap,

    I'm moron.  You didn't know it yet?

    Come on...

   "The way we disperse static IP" ain't imagination, its fact...  We 
spread a /20 on dynamic dialup and dsl over 2 provinces and since most 
of the residential services is build like this you cannot get a read of 
where that ip user is located, unless you have also access to our 
customers db and authentication account db too.

    The best you'll get is country.  Even then we have some that are 
LanEx'ed in europe and usa.

    (FYI: English is not my first language btw...  so dont expect too much)
