Hi Christian,

gethostbyaddr() returns the original IP num if it cannot resolve it to a
hostname.
Did you by any chance change DNS settings?
Or is the machine itself the DNS server?

Also, if you didn't do so already, read all usercontributed notes at
php.net:
http://nl3.php.net/manual/en/function.gethostbyaddr.php

Good luck.
If you solve your problem, please post your findings here and/or at
www.php.net.

Regards,
