Lets see. My php is a little rusty, but I think the following might do what you need.

$strHost = gethostbyaddr($_SERVER['REMOTE_ADDR']);

In my case, this would return something like...

UNIQUEHASH-UNIQUEHASH.cpe.net.cable.rogers.com

I would imagine what you want is just the rogers or the rogers.com. You can perform some string manipulation functions on $strHost to retrieve that.

Warning: gethostbyaddr() [function.gethostbyaddr]: Address is not a valid IPv4 or IPv6 address

mate this the error i got .. my simple code was

<?php

echo gethostbyaddr($_server['REMOTE_ADDR']);

?>

when i tried it on local server, it gave my my computer name, but when i put it online, it gave me this error..

Lets try to debug this. Output $_SERVER['REMOTE_ADDR'] by itself and post the result.

here is how i changed the code..

<?php

$ip=$_SERVER['REMOTE_ADDR'];
echo"you ip adddress is".$ip;
$isp=gethostbyaddr($ip);
echo $isp;
?>

and the output i got is

you ip adddress is **.**.177.233 **.**.177.233

that means it is returning me the ip address again, instead if ISP name ..
