The Media Access MAC address is a hardware address for all internet devices.[^1] This address is hardcoded to the network card and cannot be changed.[^1] it is used when delivering messages on a subnet.[^1] A single MAC address can have multiple IP addresses bound to it.[^1] The binding between the MAC and the IP address is handled through the “Address Resolution Protocol” (ARP).[^1] The ARP will only be used to communicate with devices on your subnet.[^1] A MAC address can be used as “hooks” to aggregate disparate datasets into comprehensive profiles of individuals.[^2] A static bluetooth MAC address is persistently used by the device .[^1] Non-resolvable private MAC addresses are cryptographically-generated and used as temporary addresses when two devices pair.[^2] Bluetooth MAC addresses can be used as band-identifier data for wearable devices.[^2]
[[Ethernet]] – has a 48-bit MAC address
[[BLE Protocol]] – can use the MAC address to determine which device it should pair with
[[Apple Watch]] – uses randomized Bluetooth MAC addressses
[[Tails]] – spoofs all MAC addresses
[[Operation ShadowHammer]] – targeted users by their MAC addresses
[[LNK file]] – EXTRA_DATA structure may include known hostnames and MAC addresses
