WebIn addition to 48-bit identifiers (which is used in almost all 802. protocols, including 802.3 (aka Ethernet) and 802.11 (aka Wi-Fi)), 64-bit ones are also used (aka EUI-64). Examples of protocols where an EUI-64 identifier is used are: FireWire, ZigBee, 6LoWPAN, 802.15.4, etc. WebEthernet packets with less than the minimum 64 bytes for an Ethernet packet (header + user data + FCS) are padded to 64 bytes, which means that if there's less than 64- (14+4) = 46 bytes of user data, extra padding data is added to the packet. Beware: the minimum Ethernet packet size is commonly mentioned at 64 bytes, which is including the FCS.

WebEach MAC address is unique to the network card installed on a device, but the number of device-identifying bits is limited, which means manufacturers do reuse them. Each manufacturer has about 1.68 million available addresses, so when it burns a device with a MAC address ending in FF-FF-FF, it starts again at 00-00-00.
