{{Admon/note | Obtaining Remote MAC Addresses| The term MAC address stands for Media Access Control address, which provides a unique ID to prevent confusion among computer systems within a network. <br /><br />While we use 32bit IP addresses to communicate over an internetwork, on the local ethernet network packets are delivered to a 48bit hardware address (sometimes called a MAC address). The ARP protocol resolves 32bit IP addresses to 48bit MAC addresses by using a broadcast and caching the results. We can examine the ARP cache to get the MAC addresses of other computers on our local network.}}
