Although the MAC of a computer or device cannot be changed as an IP, there are ways (not legal, by the way) to supplant them. This way we can connect to the Internet by hiding our MAC and making the router and the local network think that we are a different computer.
What is the MAC address of a computer?
Unlike the IP address of our computer, which is a logical address used to identify our PC within the local network and that we can change it, the MAC address, or physical address, is a unique address for each device or network card in the world and that, furthermore, is not can modify.
The MAC address it is associated within a read-only chip (ROM) on each network card. These MAC addresses have to respect certain standards and, before they can be marketed, they must be validated by the corresponding body, which in this case is the IEEE (Institute of Electrical and Electronics Engineers).
While the IP address allows us to configure computers that use that IP, regardless of what they are, the MAC allows us to always identify a specific computer. Regardless of your IP. Thus, with the MAC we can restrict Internet access to some devices, configure bandwidths and priorities in the router, open ports, configure a DHCP and much more.
How to see the MAC in Windows 10
There are several ways to see the MAC address of our computer from Windows. The result of all of them will be the same, since, as we have explained, this address cannot be changed. So we can choose the easiest or most comfortable method for us.
Using CMD to see the MAC
If we are not afraid to use the Windows 10 CMD console, we can find out the MAC with a simple command. To do this, we open a CMD window in our session (it does not have to be with Administrator permissions) and we will execute the following command:
ipconfig / all
All the results related to the network card of our computer will appear. What we should look for is a section called “Physical address”. This will be the MAC of the computer.
CMD has a large collection of commands to control the status of the Windows connection. We recommend you memorize them, since on more than one occasion they can be useful.
From network properties
Another simple way to see the MAC address of the computer is from the network properties section of the Windows 10 Settings menu. To do this, we will right-click on the Windows 10 network icon, and choose the option “Open network and Internet settings”.
A new section will be opened with the status of the network. We can also get to this point by opening the Windows 10 Settings menu, from the “Network and Internet”> “Status” section.
We will click on the link «See network properties». In the new window that will be displayed, we can see everything related to the network connection of our computer. The section “Physical address (MAC)” will allow us to find out what the MAC address of our PC is.
From the control panel
Another way to see the MAC of our PC is from the Windows Control Panel itself. To do this, we will look for this panel from the search bar of the operating system, and we will move to the Networks and Internet section> Network Center and shared resources.
Here we will select our connection and open the details screen in it. Among all the details we can find the MAC of the network card associated with said connection.
Now we only have to use the MAC to use it wherever we want. For example, to open ports on a router or configure DHCP.
