InetAddress just does a lookup on your hostname to determine your local host
address. If your host name resolves to 127.0.0.1 (for instance, if the first
entry in your /etc/hosts file maps 127.0.0.1 to your hostname rather than just
to localhost and localhost.localdomain), then that's the IP address you'll get.
Unfortunately, there's no way in Java to get any more information about the
network addresses on your system. So you pretty much have to fix your hosts
files. (And no, InetAddress.getAllByName(String host) doesn't do what you
think it does--it returns all the IP's that answer to a given hostname, rather
than the addresses of all the interfaces on a multi-homed system.)
Good luck.
