You can find the MAC address of each device at the last line of the device description, followed by link/ether and it’s 52:54:00:5c:92:bf in my case. Generally, the wireless device names will be wlan0, wlan1, wlan2, wlo0, wlo1, and wlo2, whereas the Ethernet (wired device) will probably have eth0, eth1, eno0, eno1,enpls0, or enpls1. Open up your terminal and use the following command, and it will bring the address of the present network cards in your system: ip linkĪnd you’ll be met with the following output: 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.
This library utilizes this information when available. node ≥ 0.12 and io.js report MAC addresses in os.networkInterfaces().works on Linux, Mac OS X, Windows, and on most UNIX systems.There is no web api reporting the mac address of the machine (and that is a good thing). This useful for example for distributed/scaled applications, for example when generating UUIDs.Īlso it seems to be worth noting that this library is not intended to be used in a browser. This library reports the mac address of the server the application is running on. Reporting the mac address is not in any way similar to reporting the IP address of the client that accesses your application. The host system (see API + Examples below).Ī common misconception about this library is that it reports the mac address of the client that accesses some kind of backend. This library allows to discover the MAC address per network interface and choosesĪn appropriate interface if all you're interested in is one MAC address identifying While a host may have multiple MAC addresses – since every network interface may
Retrieve MAC addresses in Linux, OS X, and Windows.Ī common misconception about MAC addresses is that every host had one MAC address,
