Remote User IP

how to get remote user IP

[vipink]

Is it possible to fetch remote USER IP (instead of ISP/router's IP) or computer name using PHP?

[Habtom]

May be $_SERVER['REMOTE_ADDR']

Which IP does this hold anyway?

[vipink]

$_SERVER['REMOTE_ADDR'] gives the IP of the router/ISP and not the actual user. There can be serveral users behind one router/ISP. I want to track if the same user is filling the registration form or the different users. I need either the computer name or the remote user ip

You can use cookies [us2.php.net].

No. You can't see the computer's LAN IP or computer name. Cookies/sessions are the way to go for user identification.
