Abstract
A method and system for provisioning network addresses in a data-over-cable system. Provisioning of network addresses allows multiple “always-on” network devices with multiple associated devices to be used on a data-over-cable system with a limited public network address pool. The “always-on” network devices provide services, such as, Voice over Internet Protocol (“VoIP”), that typically require instant access to data-over-cable system. Network devices such as “always-on” cable modems may allocated private network addresses (e.g., Internet Protocol addresses) on the data-over-cable system. The private network addresses are not addressable outside the data-over-cable system. Other network devices associated with the cable modems, such as customer premise equipment, may be allocated public network addresses (e.g., Internet Protocol Addresses) on the data-over-cable system. The public network addresses are addressable outside the data-over-cable system. The network address provisioning is accomplished by selecting a private network address marker and a public network address marker for selected network devices and using an extended Addre…
