There are serveral Linux networking commands that can be used to get the MAC address of the WiFi or LAN cards.īasically, use the same command that you use for checking the IP address. Method 1: Find MAC address using command line I’ll show both command line and GUI methods.

In this tutorial, I’ll share the steps for finding the MAC address of your desired networking interface in Linux. The MAC address, also known as the physical address, is a 12-digit hexadecimal code (48-bits) and is represented as MM:MM:MM:SS:SS:SS So, your WiFi card has a MAC address, and so does the Ethernet (LAN) port. It is because the MAC address is a core part of networking, and each networking peripheral device has its own MAC address. The IEEE Registration Authority Committee assigns these MAC prefixes to its registered suppliers.When you are learning networking or troubleshooting it, you would need to know the MAC address.Ī computer can have more than one MAC address. The OUI (Organizational Unique Identifier*) is the first 6-digits of the MAC Address (for example, 00:40:96). The MAC Address is a hexadecimal number with 12 digits (6-byte binary number) commonly written in Colon-Hexadecimal notation.

It is separated into two sublayers in the IEEE 802 standard:īecause millions of network devices exist and we need to identify each uniquely, the MAC address is unique worldwide.

The Data Link Layer uses a MAC address to route a data packet from a source to its destination. It is a physical address associated with every networking device. MAC (Media Access Control) is a 48-bit unique identifier assigned to Network Interface Controller. This article will discuss addressing in DLL, which is MAC Address, and demonstrate how to get the MAC Address of the user using JavaScript. In Computer Networks, various addresses are introduced, each working at a different layer.įor example, a Media Access Control address is a physical address that works at the Data Link Layer. To communicate or transfer data from one computer to another, we need some address.

Use the ActiveX Object to Get MAC Address in JavaScript.
