  • Virtual IP interface
    Publication number: 20060072601
    Abstract: The number of IP addresses required by a central office device, which is connected to a network segment and a number of customer internet devices to pass packets between the network segment and the customer internet devices, is reduced to one by using an IP address and a subnet mask that are associated with the network interface as a virtual interface. The subnet mask allows packets to be routed to the central office device, which then forwards the packets to the customer internet devices.
