Server variable for users isp

[dkin]

I can not find how to access this variable. I know its a rookie thing but I really need it. If anyone knows how to access it please reply.

[php.net...]

$_SERVER['REMOTE_ADDR']

<added>wait, ISP or IP?

[dkin]

ISP for instance mine would be something like .cable.rogers.com

[jatar_k]

do this and see if it is available somewhere in there

echo '<pre>';
print_r($_SERVER);
echo '</pre>';

that will spit out all the server vars for you to look at

hmmmm, its not in there. Then how do other sites get it, there is a cookie on my machine that displays this

28#33#.com#15340#9164#.cpe.net.cable.rogers.com#IPHERE##ISO-8859-1%2Cutf-8%3Bq%3D0.7%2C*%3Bq%3D0.7#-1968#9112#9093#0#5

how could they have gotten "cpe.net.cable.rogers.com" that?

They are probably using reverse dns. A Reverse DNS lookup will give you the DNS name of a computer when all you know is the IP address (which jk has already showed you how to find)
