In the example above, XXXXXXXXXXXX and YYYYYYYYYYY are the MAC addresses of the two LAN connections in use. The second line indicates the type of link layer in use and the current hardware address (MAC address). The first line summarizes the device's current name, the flags set on the device, MTU (Maximum Transmission Unit), etc. For each device, there are two lines summarizing the link state and characteristics. The ip utility will list a few parameters of the device. After it's tried that for about a minuet it goes to the BIOS boot selector. The DHCP has some dots followed by a rotating progress bar.

Every PC's network device needs a unique MAC address.

The MAC address is an important parameter of network equipment, including PC hardware or servers.
