IP-adresses -> domain

[Anon]

Hi there!
I log my visitors IP-adresses in a mySQL-db,
on a secret stat-site I want to list all
these IP-adresses and also what domain a
certain IP-adress belongs to.

How do I do that?

Thanks in advance!

Regards
Daniel

You can begin by getting the hostname!
Check the "gethostbyaddr" function:
http://www.php.net/manual/en/function.gethostbyaddr.php

A short example:

<?php
$REMOTE_ADDR = '209.61.191.11';
$REMOTE_HOST = gethostbyaddr($REMOTE_ADDR);
echo $REMOTE_HOST;
?>

Lycka till!
