If all else fails, but you have shell access, Unix/Linux
servers can use this for a timeout response:
shell_exec('host -W 2 0.0.0.0');
Where 0.0.0.0 is of course the IP, and '2' is the number
of seconds for the timeout. This returns a more detailed
string of info, with some additional text which might vary
depending on the system, so if you want a string with the
hostname and nothing else, you'll have to do some substring
cutting. There should be an equivalent of 'host' for
Windows users to execute, but it isn't my platform.
