I've got some code doing IP checking using the HTTP header...but would like to improve it....
Is it possible to reverse lookup (like here http://www.whatismyipaddress.com/reverse.asp) to find the domain with PHP? I assume a DNS lookup requires an external server somewhere? Sounds weird I know but I want to also block a specific domain rather than a range of IPs (as IP addresses can and do change...) and wondering how/if this was possible? thanks Tim -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
