Okay, I couldn't keep my programming fingers away from the keyboard, so I created a small application this afternoon that will show you the MAC address for the typed in IP address. You can type it in DEC or BIN. This is version 1.00, so please ignore small errors. If you type in non-digits in the IP octets, it will give you an error. Should you find other errors or if you believe that the calculation is wrong, please let me know. Follow the Cisco King link below and click on Free Software.
