Answer 1

If you have an IP address then sometimes it will be useful to try to resolve the host domain name for that particular IP address.
There is a built in function that accepts the IP address and will find the host name.
In order to do this, code like the below will help:

<?php $ip = $REMOTE_ADDR;//capture IP $domain = GetHostByName($ip); ?>
