> Promlem is, that getByName returns null when resolving NetworkInterface by its subinterface name (net0:1 in this case). See following example.
> {noformat}
> Enumeration<NetworkInterface> interfaces = NetworkInterface.getNetworkInterfaces();
> while (interfaces.hasMoreElements()) {
>     NetworkInterface nic = interfaces.nextElement();
>     Enumeration<NetworkInterface> subInterfaces = nic.getSubInterfaces();
>     while (subInterfaces.hasMoreElements()) {
>         NetworkInterface subInterface = subInterfaces.nextElement();
>         System.out.println(subInterface.getName());
>         System.out.println(NetworkInterface.getByName(subInterface.getName()));
>     }
