However, this approach is an inefficient use of IP addresses that are currently in short supply. This device could be a broadband modem, for example. The customer is free to build a home or small business network behind this modem, but the ISP expects the MAC address to match the registered value at all times.

    Whenever a customer replaces their modem or adds a broadband router, the MAC address will no longer match that registered at the ISP, and the ISP will disable the customer's Internet connection. One way to solve this problem is to call the ISP and ask them to update the registered MAC address to match the new hardware. A more efficient way to solve this problem is to configure the device so that it advertises the original MAC address, even though it's hardware is built to utilize a different MAC address.

Likewise, the ifconfig command available in Linux and other flavors of Unix supports changing MAC addresses with the necessary network card and driver support.

    The MAC address is an important element of computer networking. Computer operating systems and broadband routers support viewing and sometimes changing MAC addresses. Changing a MAC address can be necessary in some cases to keep an Internet connection working. Why MAC Addresses?
