public byte[] getHardwareAddress()
                          throws java.io.IOException

Retrieves the hardware address of this network interface. The native OS is queried via the appropriate OS calls to retrive the hardware address of the interface (MAC address). This is a direct call, not cached data.

Returns:

hardware address as an array of bytes; this method returns null if interface doesn't have or is incapable of having a hardware address such as loopback interfaces and others

Throws:

java.io.IOException - if there was a problem retrieving the address
