Determine MAC-addresses in your network

Sometimes it's needed to identify MAC-addresses of devices in your network. Simply execute arp -an. This command returns a list like this:

$ arp -an
Address                  HWtype  HWaddress           Flags Mask            Iface
10.10.0.11               ether   00:04:ff:ff:ff:d0   C                     eth0
10.10.0.16               ether   00:04:ff:ff:ff:a6   C                     eth0
raspbmc.local            ether   00:1f:ff:ff:ff:9c   C                     eth0
