Eiolon Posted April 3, 2013 Share Posted April 3, 2013 PHP probably has nothing to do with this, but I just want to make sure. I get the hostname of computers in our LAN on many occassions. However, sometimes it is read and displayed differently. I have not been able to determine what causes it. Using code: $hostname = gethostbyaddr($_SERVER['REMOTE_ADDR']); I will get the hostname displayed as either: JOHNSPC or JOHNSPC.domain.tld It will randomly decide which one to display. I just wanted to make sure there is nothing I can do in PHP configuration to make sure it is consistantly read as one or the other. I know I can make it read only up to the period, which I may end up having to do.

trq Posted April 3, 2013 Share Posted April 3, 2013 I'm not exactly sure how the internals of gethostbyaddr() work but I would assume it's a simple DNS lookup of some sort. Maybe your server is switching between different DNS servers to do it's lookups? These servers may indeed have different hostnames registered.
