In practical usage, layer 2 MAC address is converted from layer 3 protocol addresses such as Internet Protocol (IP address) by ARP (Address Resolution Protocol), which then allowed each host to be uniquely identified and frames to be marked for specific hosts on broadcast networks, such as Ethernet. In operating system, MAC address is often represented in 12-digit hexadecimal number. As such, all network cards, whether it’s of Ethernet NIC, Gigabit Ethernet NIC or wireless 802.11a/b/g/n/ac WiFi or HiperLAN adapter, should have different MAC addresses, which also known as Ethernet Hardware Address (EHA) or adapter address.
