Problem with gethostbyaddr

[christian9997@hotmail.com]

Hi

Since yesterday about 11.00 CET the gethostbyaddr function doesn't seem
to be working. All I get is the IP address back. Is this something
general to all PHP users or is this specific to my server?

Thanks

BTW what's the difference between comp.lang.php, alt.php and
alt.comp.lang.p hp, shouldn't these groups be merged?

Regards

Just tested it on my localhost and it works so it must be a problem on
the server.

Does anyone know what was changed on the server to stop it working?

Thanks

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.
