Use the getNetworkInterfaces() method of the NetworkInterface class to get all the network interfaces, and then loop thru each interface to get the ip addresses associated with that interface.

Enumeration<NetworkInterface> networkInterfaces =
   NetworkInterface.getNetworkInterfaces();
while (networkInterfaces.hasMoreElements())
{
   NetworkInterface networkInterface =
       networkInterfaces.nextElement();
   List<InterfaceAddress> addresses =
       networkInterface.getInterfaceAddresses();
   for (InterfaceAddress address : addresses)
   {
      InetAddress inetAddress = address.getInetAddress();
      System.out.println("Name: "+
         inetAddress.getHostName());
      System.out.println("Address: "+
         inetAddress.getHostAddress());
   }
}
