That’s because there is no PTR record for that IP.

The script works fine for me on Linux - has for some time. The docs specifically say "Returns a resolver object. If given no arguments, new() returns an object configured to your system's defaults. On UNIX systems the defaults are read from the following files, in the order indicated:<br/><br/> /etc/resolv.conf<br/> $HOME/.resolv.conf<br/> ./.resolv.conf"<br/><br/>So it uses your system resolvers. The output is a comma-delimited list of hostname-ip mappings, I suppose I could be clearer that there are newlines separating the host-ip pairs. Can you be more specific?

The default nameserver in the module is broken, so you need to supply one in your code. Also the output isn’t as documented here.
