While you may not have to worry about your device’s MAC address most of the time, there are times you need to know your network adapter’s MAC address. This way, you can identify the device or configure networking permissions on your router. Whatever your reasons for needing your MAC address, we’ll show you several ways to do it on both Mac and PC.
What is a MAC Address?
The MAC address is a unique 17-character (00:1A:C2:9B:00:68, for example) which serves as a hardware identifier that’s embedded on your computer’s network interface controller (NIC) card. The unique identifier is assigned by the device manufacturer and permanently tied to your device. This allows for communication between devices within a local network to initiate a connection. There are two main types of MAC addresses: Universally Administered Address (UAA) and Locally Administered Address (LAA). The UAA is the more popular type, which is assigned by the device manufacturer, while the LAA changes your adapter’s MAC address. You can assign the LAA to your network device and it will override the address assigned by the manufacturer. Your device’s MAC address is sometimes confused for the IP address even though both are used to identify your device on the internet, but there are some major differences. MAC addresses are permanently assigned by the device manufacturer to identify your machine from others and are designed not to be modified. IP addresses handle the logical routable connection from your devices and networks, and can change based on location. Your device’s MAC address is used inside your local network, while the IP address can be used across the world to identify network devices.
