Some ISPs(a ISP is a company that provides Internet connectivity to home and business customers) , typically cable modem providers, sell Internet subscriptions on a per-address basis. Occasionally the ISP manages these subscriptions by assigning a static (fixed) IP address to the customer. However, this approach is an inefficient use of IP addresses, which are currently in short supply.
More typically, ISPs manage single-address subscriptions by registering the MAC address of the device that connects to the ISP. 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.
