How can I find all locally bound IP addresses in Java?

Question

I would like to have all locally bound IP addresses, basically an array of java.net.InetAddress. I know I can call InetAddress.getAllByName() with the host name, but I was wondering if there is a more direct way that doesn't involve DNS and/or knowledge of the host name.

java.net.NetworkInterface.getNetworkInterfaces() will give you an enumeration of the available network interfaces. You can then invoke getInetAddresses() on each NetworkInterface to get the addresses bound to this interface.
