If we look at a command prompt and use the command config, we can type in an IP config and we can see the MAC addresses and the IP addresses for the ethernet adapters in our machine. Now we have two. This is our main one right here, and if we look at the physical address right here, we can see this hexadecimal number here. That is the unique MAC address for this network interface card. Now, the secondary one, just in case somebody has a question, this actually comes from our virtual box VM. So if you remember in an earlier episode…
