fan-page

Hello,

I am creating a poll script for a facebook fan page:

http://www.facebook.com/apps/application.php?id=115400635147687&v=app_115400635147687

I am getting the IP using:

$_SERVER['REMOTE_ADDR']

But the problem is that each time I refresh the page, or make an ajax call, the IP is changed everytime. Someone told me that facebook has many IPs, proxies.

Basically I need to save the IP in database, so that once a user from certain IP has voted, he should not be able to do so again.

What is the solution or alternative to this?
