K-MAC is a network card MAC address (physical address) modifying tool for Windows. For users who are suffering from network bandwidth limitation or frequent ARP attacks from LAN, this tool can be regarded as a clever solution.

 Main Purposes 

  1. Remove network access restrictions from the router or network administrator  (limit bandwidth via binding the MAC and IP addresses; block accessing to certain websites for some PCs, etc.)
  2. Escape malicious ARP attacks from viruses or other clients in the local area network (LAN)
  3. In LAN, cheat the router through the simulation of other PC's MAC address, so that make its network fault or paralyzed.

Application Example

After changing your IP the same as the host IP which can connect to the Internet, and then change your MAC address the same with it too using K-MAC. Then you can surf the Internet again or return to normal bandwidth (if the network administrator bound the IP and MAC to limit).

When the MAC address changed successfully. You need to disable/enable the selected network interface or restart your computer for the changes to take effect. BTW, you can also rollback to your original MAC address anytime, also with one click!
