Connected Device Transparency with the StarTech.com MAC Address Changer UtilityThe DK30CHDPPDUE, includes a free Windows® application that enables you to better manage your enterprise network security. When you connect to your network through the ethernet port of the dock, the computer’s MAC address is typically not broadcast to the network, as your network only sees the MAC address of the docking station. However, the StarTech.com MAC Address Changer or Cloning software enables the USB-C dock to use MAC address spoofing of the connected Windows laptop rather than the MAC address of the dock itself. This ensures your network administrators have full visibility of each device on the network and can monitor and limit activity accordingly.
