Get the MAC address of BluetoothĪs I mentioned earlier, all networking devices have a physical address. 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.

If (ioctl(sock, SIOCGIFCONF, &ifc) = -1) Ĭonst struct ifreq* const end = it + (ifc.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. Int sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_IP)

You also want to skip the loopback interface. The mac address will be obtained as a 6-octet binary array. You need to iterate over all the available interfaces on your machine, and use ioctl with SIOCGIFHWADDR flag to get the mac address.
