title: $_SERVER["REMOTE_ADDR"] gives server IP rather than visitor IP
body: <p>I'm trying to track IP addresses of visitors. When using <code>$_SERVER["REMOTE_ADDR"]</code>, I get the server's IP address rather than the visitor's. I tried this on multiple machines at multiple locations and they all resulted in the exact same IP. Is there some PHP/server settings that could be affecting this?</p>
