That name is looked up by DNS and can return 0.0.0.0 if not found (e.g. the name is missing, wrong or the machine has been moved somewhere (a different domain?) that cannot resolve the name). Linux gurus, feel free to correct/complete this picture.
On Unix, you get back nil if the host does not exist:
NetNameResolver addressForName: 'aoeuaoeaoeu' --> nil
This seems better than 0.0.0.0.
