How to Change your MAC Address
June 8, 2008 – 4:33 pmA MAC Address is the unique identifier of your network interface.
Every Network card manufacturer has its own MAC Address prefix for its cards. For example:
“00-0C-F1-xx-xx-xx” is one of Intel’s prefixes.
The rest of the MAC Address defines where the network card it is located in the world, and which distributor sold it.
So basically if a network card manufacturer wanted to know who owns a particular card (assuming it was manufactured by that same company), they could know.
If you want to perform a search on someone’s MAC Address, you can use the MAC Address Lookup

How to change your MAC Address:
Recent network adapters provides the ability to change the address through the adapter driver.
Check if your adapter allows this by entering:
Control Panel -> System -> Hardware -> Device Manager -> Network Adapters -> Right click on your network adapter you wish to change its MAC Address -> Properties -> Advanced -> Network Address
Under the Network address you can place any address you like (0-9 and A-F combination).
If you do not have the ability to change your address through the driver, Use applications like SMAC to change your network adapter MAC Address.
Be careful, If you change your MAC Address to be identical as another adapter in your intranet, they will collide and you will not be able to connect to your local intranet.
P.S
If you are using VMware your MAC Address is already spoofed.
