The IEEE 802 MAC address originally comes from the Xerox Network Systems Ethernet addressing scheme. The b0 bit distinguishes multicast and unicast addressing and the b1 bit distinguishes universal and locally administered addressing. However, two NICs connected to two different networks can share the same MAC address. Network nodes with multiple network interfaces, such as routers and multilayer switches, must have a unique MAC address for each NIC in the same network. MAC addresses are formed according to the principles of two numbering spaces based on Extended Unique Identifiers (EUI) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48, which replaces the obsolete term MAC-48, and EUI-64. The address typically includes a manufacturer's organizationally unique identifier (OUI). Many network interfaces, however, support changing their MAC address. Each address can be stored in hardware, such as the card's read-only memory, or by a firmware mechanism. MAC addresses are primarily assigned by device manufacturers, and are therefore often referred to as the burned-in address, or as an Ethernet hardware address, hardware address, or physical address. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.

The physical address will be listed under "MAC Address.".When the "Network Settings" list appears, select the first option which is titled "Settings and Connection Status List.".

FIND MY MAC ADDRESS ON MAC TV
Alternatively, you may find the MAC address printed on the UPC label on the Apple TV box.Look for the MAC address next to "Wireless ID" for the wireless connection.From the main menu, choose Settings, and then click About.Scroll down to see your "Wi-Fi MAC address".The wireless MAC or physical address is formatted in six groups of two hexadecimal digits.
FIND MY MAC ADDRESS ON MAC SERIAL NUMBER
This address is typically located physically on the device near the serial number or can be found in the menu system (i.e system information, about menu, etc). In order to register the device you will need to locate the wireless MAC address or wireless physical address.
