When you get a command prompt window, enter the following command. After you fill in the results, right-click on the command prompt icon and select “Run as administrator”. Click the Start button and type cmd or Command Prompt. To do this, we first need to open a command prompt. On Windows, to see the MAC address, you just need to run one command to find the MAC address. The fastest way to deal with the network is through the command line.

Now, if you want to mess with your network, or join one that has MAC address filtering enabled, you need a MAC address or MAC spoofing. However, you can use third-party apps to find the MAC address of any device on the network by finding their IP address. The only way is to boot your device and use the following methods.
#How to find mac address on linux serial number#
Unfortunately, you cannot find the MAC address of a device by its serial number or on the Internet. Just make sure no two devices on the same network have the same MAC address. Well, that means 2 things: first, the website can’t figure out your MAC address Second, you can change your MAC address to whatever you want. Instead, it contains the MAC address of your router. When the packet leaves the router, it does not contain the MAC address of the device. The MAC address is only relevant up to the router level. The MAC address is hardcoded into the network card, which means it is unique and each device has a different MAC address. Unlike your IP address, which changes every time you connect to the Internet, the MAC address remains the same. This MAC address (short for Media Access list) looks like “F8-28-19-4E-95-61”. In simple terms, every electronic device that connects to a network has a unique identifier called a MAC address or physical address. So what exactly is a “MAC address” and how do you find it? Now, when you report this problem to the network administrator, he smiles and asks for the MAC address of the device.
You have all the required credentials, but you still cannot connect. In the above example, XXXXXXXXXXXX and YYYYYYYYYYY are the MAC Address of the two LAN connections in use.So, you try to connect to new Wi-Fi, but it doesn’t work. The second line should always indicate the type of link layer in use and the current hardware address (MAC Address). The first line summarizes the current name of the device, the flags set on the device, the maximum transmission unit (MTU) and so on. The ip utility should list several parameters of the device. For each device, two lines should summarize the link state and characteristics. Link/ether YYYYYYYYYYYY brd ff:ff:ff:ff:ff:ff Link/ether XXXXXXXXXXXX brd ff:ff:ff:ff:ff:ffģ: wlp2s0: mtu 1500 qdisc mq state DOWN mode DEFAULT group default qlen 1000 Launch Terminal and enter the ip link command: ip link showĮxample Output: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000Ģ: enp1s0: mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000 Every PC’s network device should have a unique MAC address. MAC address is another critical parameter of a network device, including your PC’s hardware or a server. Typically, eth0 is for Ethernet connection, and wlp2s0 for Wireless connection.įor example, use eth0 : ip addr show eth0 Finding the MAC Address of the Linux System Inet6 1:2:00:33:333/64 scope global mngtmpaddr noprefixroute dynamic Valid_lft 548176sec preferred_lft 61403sec Inet6 AB:AD:AK:AI/64 scope global temporary dynamic Valid_lft 61791sec preferred_lft 61791sec Sample Output: 1: lo: mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000 ip route list | grep defaultĪlternatively, you can also use device name in particular too, but you should know the names of network devices for that. If you are only interested in the default IP address that connects to the internet, use a grep parameter to list that one. It should display all available IP address including device names. ip route list ip route list command usage in Ubuntu 17.10
