MAC address – Media Access Control address Twelve-character hexadecimal hard- ware address organised in pairs (e.g. 1A-2B-3C-4E-5F-66) of an internal or external network adapter/network- capable device interface (computer, router, etc.) for wireless and/or wired network connection (also called Ethernet address, Ethernet ID, air- port ID or Wi-Fi address). The MAC address can be used as a basis for automatic configuration of devices connected to an IP-based network and is used by various network proto- cols (e.g. DHCP). In theory, the MAC address of a network-capable device should be globally unique and it was regarded as a unique identifier within a network. The preset MAC address of a network adapter itself cannot be changed. However, the MAC addresses to be communicated can be changed as desired by software or created at random using existing device functions (e.g. smartphones) in order to prevent unique identifica- tion or to use replacement devices with the same ID. The MAC address also contains the
