ISP Locations

[mj9999]

I am using the follow API call with php like this.

http://api.hostip.info/get_html.php?ip=$_SERVER['REMOTE_ADDR']

I then take the output and use a php function to get just the state abbrevation on the end. That is then used to keep visitors from a certain state from viewing a web page.

It seems to be working great overall but I have been contacted by a couple of visitors who have said they are not from the location on record for that IP address. I mean not really close.

Does that mean some IPs are just between updates.

I also suspect that access through an air card could cause that. Is that possible?

I appreciate your service, which offered a really easy solution for me.
