I think the right answer is "There is no location information in an IP
address for the reason given, and for additional reasons (such as
"tunneling", and various mobility schemes).  Telephone numbers,
particularly North American Numbering Plan Area numbers, do no contain
the location information they used to.

You can make statistical estimates (the odds are numbers in range X-Y
are in area Z).
