Mac address? I don’t even own a Mac, you might be thinking to yourself. But a MAC address (note the caps) is not directly related to Apple computers. Instead, it’s a unique identifier for any device that connects to your home network, either via Wi-Fi or cable to the router. Read on to find out more about them and how to find the MAC address for your devices.
What is a MAC address?
MAC in this instance stands for Media Access Control, not a shorthand for Macintosh.
As we explained above, any device that connects to your router – be it a computer, smartphone, smart speaker or Sky TV box – will have its own, unique Mac address. This is set at the factory where the device is manufactured and can’t be changed by the user.
What use is a MAC address?
It can be useful for identifying hardware on your network. If you go into your router’s settings and find a list of devices connected to your network, most will have a fairly obvious identifier, such as “Galaxy S9” for your Samsung smartphone.
However, some devices may only list an IP address and a MAC address. The IP address is normally assigned by the router every time the device connects, which means it’s constantly changing. However, the MAC address will always remain the same. So, if you’re trying to work out what a device connected to your router is, knowing its MAC address can help.
Some routers also allow you to block devices other than those with an approved MAC address. So if someone were to obtain your Wi-Fi password, for instance, they still wouldn’t be given access to your network.
