It is important to note that manufacturers sometimes use different names to describe the MAC address, such as Hardware ID, Physical Address, Wireless ID, Wi-Fi Address, etc. 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. So if your 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 hypen separating every two digits (an octet), making it easier to read.Įxample: A MAC address of 2c549188c9e3 is typically displayed as 2C:54:91:88:C9:E3 or 2c-54-91-88-c9-e3. The NIC is where you make your physical connection to the network, by plugging in an Ethernet cable or connecting to a WiFi signal. The MAC address is tied to the Network Interface Controller (NIC), a subcomponent of the larger device. Just like each house has it's own postal address, every device connected on a network has a Media Access Control (MAC) address, that uniquely identifies it.
