Getting IP of referrering page

Is there any function or script that can give me the IP address of a referring local page?

Basically something between $_SERVER['HTTP_REFERER'] and $_SERVER['SERVER_ADDR']

Thanks.

TRy using the gethostbyname() function.

Example :

echo gethostbyname('google.com');

would give an outcome of 216.239.59.99

Hope this helps!
