Address
Your computer’s local address is its unique address on your network.
This is also referred to as the computer’s MAC (Media Access
Control) address.

• Use Computer MAC address. If your ISP requires MAC
authentication, you can use this setting to disguise the modem
router’s MAC address with the computer’s own MAC address.
• Use This MAC Address. If your ISP requires MAC authentication,
you can manually type the MAC address for a different computer.
The format for the MAC address is XX:XX:XX:XX:XX:XX.

plan to install the modem router in a setting where you will be manually administering the IP address space on the LAN side
of the router.
