List of MAC addresses on the LAN

[system]

I need to list the IP and MAC addresses of all the devices connected to my local network. I need something similar to the Windows commande ARP -a.

How can I do it with my Arduino Mega and Ethernet shield. Thank you to provide any good example.

Regards

André
