The first column is the interface number. The second column is the list of MAC addresses associated with the network-capable interfaces on the hosts. These interfaces can include Ethernet, Wi-Fi and Bluetooth adapters. The third column shows the manufacturer and a description of the interface.
In this example, the first line displays the wireless interface that is connected to the local network.
Note: If you have a PC with an Ethernet interface and a Wireless adapter enabled, both interfaces would be listed in the Interface List.
What is the MAC address of the interface connected to your local network? How does the MAC address compare to the recorded MAC address in Step 1?
