What is MAC address?
The MAC address, or Media Access Control, is a unique identification assigned to each device connected to a network. This address is made up of a combination of numbers and letters, and serves as a kind of "fingerprint" that allows a particular device to be unequivocally identified.
The MAC address is located at the data link layer of the OSI model. Its main function is to control access to communication media on a network, ensuring that devices communicate efficiently and orderly. It is important to keep in mind that the MAC address is physical and is recorded on the device's network card, which means it cannot be easily modified.
Each MAC address consists of 6 groups of two hexadecimal digits separated by colons or dashes. The first three groups identify the manufacturer of the device, while the last three groups are serial numbers assigned by the manufacturer. This ensures that each device has a unique MAC address in the world. Additionally, it is possible to distinguish between universal MAC addresses (assigned by the IEEE) and local MAC addresses (randomly generated).
Why do I need to know the MAC address of my PC?
The MAC (Media Access Control) address of your PC is a unique identification assigned to the network card of your computer. Although it may seem like an insignificant technical detail, knowing the MAC address of your PC can be useful in several situations. Here we explain why you need to know it:

To use the ifconfig command to find the MAC address of a device on Linux, follow these steps:
1. Open a terminal in your Linux distribution.
2. Type the command `ifconfig` and press Enter. This will display information for all network interfaces on your system.
3. Find the specific network interface for which you want to find the MAC address. You can identify it by its name, such as “eth0” or “wlan0″.
4. In the line corresponding to the network interface that interests you, look for the »HWaddr» field. The MAC address of the interface will then be displayed.
Remember that on some more modern Linux systems, `ifconfig` has been replaced by the `ip` command, which you can also use to find the MAC address of a device. In that case, instead of look for the “HWaddr” field, you must look for the “link/ether” field. In short, the MAC address is an important key to how networks work, and the ifconfig command in Linux is an excellent tool for finding it and using it for network administration and troubleshooting tasks.
