How to find the MAC address of your Windows 10 computer

Before entering the matter, we have to clarify a series of terms that, perhaps, you are not too clear. What do we know as a MAC address? Each manufacturer of mobile, computer, tablet, assigns a unique identification number to its network card. MAC consists of three letters that, broken down, come to mean Media Access Control, that is, Multimedia Access Control. The MAC address is made up of 48 bits (six blocks of two hexadecimal characters) and is unique for each device. It is, so to speak, the license plate of the network card of our team.

Half of the bits that make up a MAC address correspond to the manufacturer and the rest to the model of the equipment in question. This MAC number is used, for example, to identify a computer that is connected to our network, whether it is ours or not. There are web pages that act as a MAC number search engine to find out which brand a certain computer connected to a network belongs to. In this way, we can restrict any equipment with a MAC address that we do not know, so it is important to know which is the one of the devices with WiFi that we have at home.

How to know what is the MAC address of our computer in Windows 10

If you have a computer with Windows 10 operating system and you want to know what its MAC address is, this is all you have to do. Follow the steps carefully and don't skip any. The process is not dangerous but we are not responsible for any modification or alteration that you make for not following the instructions properly .

First, we are going to press, at the same time, the Windows key (you can easily identify it since it is the key that has the Windows logo on it) plus the letter 'R'. A small window called 'Run' will open in which we will have to write the letters 'CMD' but without quotes. In this way we will go directly to the computer section 'Command Prompt'. We can also access the Command Prompt by typing in Cortana's search bar 'Command Prompt', ' CMD ' or 'Run', always, of course, without quotes.

On the screen that appears we will have to write, without quotes, ' ipconfig / all '. In the list of data that appear we will have to look for the one that says 'Physical Address' as we see in the following screenshot.

Make a good note of all the MAC addresses of the devices you have at home. Now, let's see what computers we have connected to our network and see if, indeed, we know all of them. To do this, we are going to use a third-party application for Android that we can find in the Play Store application store called 'Fing. Network scanner '. This application is free, has no ads and is quite light: 13.20 MB.

Once installed and opened, it will ask us to enable location permissions. We grant it and, automatically, it will detect which WiFi network we are connected to and it will display all the devices that are in it. In this way we will know if there is an intruder in our WiFi, for which the MAC address can be of great help.
