A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card’s read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number and may be referred to as the burned-in address. It may also be known as an Ethernet hardware address (EHA), hardware address or physical address.
To find out MAC address for your network card you have two different options.
First option: “Command prompt”
1. Click on Start and type cmd in the Start search field than press Enter
2. In the new window, type getmac
You’ll see a list of Physical Addresses, one for each network adapter installed on your computer. In my case I have 3 physical addresses, one for dial-up, one for Ethernet and the last one for my WiFi adapter (ignore those 2 disable entrance because they are virtual graphic cards). In this moment, I’m using my WiFi network for the internet connection so I can say that my second physical address (MAC) corresponds to it because, as you can see, the other two adapters are disconnected.
Second option: “Windows interface”
1. Click on Internet Network tray icon and select “Network and Sharing Center”
2. Click on “View Status” next to your network adaptop
3. Click on “Details” button
4. Find MAC (Physical address) under Physical address field
