The local physical address assigned to a network interface controller for local communication is the Media Access Control (MAC) address.
This communication occurs between multiple devices on a network. In computer networking, different types of addresses are present, and each has its own role.
However, a MAC address is a physical address that works in the Data Link Layer in the
MAC addresses are unique
6-byte long hardware-encoded identifiers also known as
EUI (Extended Unique Identifier).
MAC addresses identify senders uniquely and receivers on a network or over a communication channel.
According to IEEE 802 Standards, the Data Link Layer is divided into two sublayers.
The first sublayer is the Logical Link Control (LLC), and the second is the Media Access Control (MAC).
On the second sublayer, MAC addresses are used by the Data Link layer to establish a communication channel.
MAC addresses are unique and used worldwide. Millions of online devices communicate through them. We use the
6-byte long MAC address in Hexadecimal for the unique identification of devices.
The first three bytes are used by vendors, and the remaining are used as a serial number of that vendor’s interface card.
Hexadecimal is a number system with base 16. Include the following numbers: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F.
Below are the types of MAC addresses:
Below are some commands to check your device’s or network card’s MAC address:
// For windows users open Command Prompt and execute Command for Windows OS: ipconfig /all
// For Linux users open your Terminal and execute Command for Linux/UNIX OS: ifconfig -a // -a means all ip link list ip address show
// For Apple users MacOS: TCP/IP Control Panel / Settings
