Do you know what a MAC address is?

 

My guess would be that most people using a PC have a MAC address even if they don't know it. The MAC address is a unique 10 digit code that is hard wired into every NIC (network interface card). The NIC is the card in your PC that allows you to communicate with a network and the internet. If your PC connects to the internet using a dial-up modem you may not have a NIC, but most PCs today come from the factory with a NIC already installed. Today's laptops typically have a wireless NIC card in them that allows them to connect to WIFI networks.

 

Why do you need to change it?

 

I can think of two main reasons why you might have to change a MAC address.

  1. A network needs to see a specific MAC address (other than yours) in order to allow you access.
  2. A software application is looking for a specific MAC address (other than yours) to see if it resides on a licensed PC.

I've run into two situations where it would have been handy to change the MAC address, but I had no idea that it was even possible. Now that I've found this cool freeware app, I will be ready the next time it happens.
