Get the local IP address associated to a local MAC address

Question

In a .properties file I store the local network interface (i.e. MAC address) which I want to be used by my Java application. Then I get that information as a property.

Now I want to get the local IP address currently associated to this MAC address. How could I do that with Java?

Note that I can't use Reverse ARP on a gateway. I don't have any gateway, I work locally only.

Thanks.

@EJP Because my users change regularly the IP address and I don't want to force them to update it in my app. But thank you. — Marc de Verdelhan

You can use NetworkInterface for this (http://docs.oracle.com/javase/6/docs/api/java/net/NetworkInterface.html):

 Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces(); while (interfaces.hasMoreElements()) { NetworkInterface i = interfaces.nextElement(); if ( i.getHardwareAddress().... ) { } }
