There are multiple ways of getting the MAC address of a system that is on either locally or remotely. But, what if your system is off, you do not have physical access to the system and you wanted to turn it on remotely using Wake on Lan(WOL)? In order to turn your computer on remotely using WOL you need to know the MAC address of that system. If you are not planned this ahead of time, finding the systems MAC address might not be very easy. What are your options?
