In general, you will find MAC addresses in the system settings, general information, or network settings/status of your device. Occasionally, the MAC address is printed on a label affixed to the bottom of a device. If laptop has both an Ethernet port and Wi-Fi built-in, you will see two MAC addresses in the system configuration. For each network interface in your device, there is a unique MAC address associated with it. Can a device have more than one MAC address? The MAC address is a 12-digit hexadecimal number that is most often displayed with a colon or hyphen separating every two digits (an octet), making it easier to read. The NIC is where you make your physical connection to the network, by plugging in an Ethernet cable or connecting to a Wi-Fi signal. The MAC address is tied to the Network Interface Controller (NIC), a sub component of the larger device. MAC addresses are assigned by device manufactures. Every device connected on a network has a Media Access Control (MAC) address, that uniquely identifies it.
