Each computer system has its own Mac address. A Mac address is the address that uniquely identifies the NIC (Network Interface Card). Well if you haven’t seen your Mac address, you can do that by typing the command ipconfig /all in the command prompt.
If in case you are bored up with your computer’s Mac address and wanted to change it then it can also be done. With a tool called Mac Makeup, you can change the MAC address of any of the interfaces present on your Windows 2000/XP/2003/Vista box. This process is also termed as MAC address spoofing.
When setting the new Mac address, you can either choose a new address of your choice, or get the new one with the help of the tool, which sets the OID part according to your preference. What you need to do is just download and install this program and start the program with administrative privileges.
Use the tool to change the Mac address of your choice. For the tutorial on how to use Mac Makeup, just visit the link mentioned below.
