A MAC address (Media Access Control Address) can be utilized as a unique identifier for individual devices on a network, specifically for Media Access Control.Ī MAC address is built-up of a 12 digit hexadecimal and is tied to the Network Interface Controller (NIC). In short, it's used as a network address in communications within a network segment. In the above example, XXXXXXXXXXXX and YYYYYYYYYYY are the MAC Address of the two LAN connections in use.A MAC address is a unique identifier assigned to a network interface controller. 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
