MadMACs

MadMACs, whose name makes us remember Mel Gibson's famous film is a tool that lets you randomly change a MAC's address and your computer's host name.

This tool is very easy to use, and it is sufficient to indicate the prefix of the address that you are using. You may access a list of manufactures by going to the following addresses: aquí.
MadMacs can modify the addresses belonging to any network device, either wireless or Ethernet.
