RE: IP to Zip Codes

2005-10-13 Thread Justin D. Scott
 I know that one can get a geographic location for a
 given IP, but does anyone know if there is a way to
 get the Zip Code a user is in from their IP?

No, as one ISP can service many zip codes, and in many cases many states.
The addresses are rotated out dynamically to users in most cases, so an IP
may be in one zip code on one request, and another zip code on the next
request if two people end up with the same IP from different areas on the
same provider.  Unless the IP is known and trusted, never rely on it.

OK.  That was how I thought it worked, although I forgot about the 
dynamic IP thing, but it really doesn't matter anyways.
