Abstract
An architecture for dynamic IP address management is disclosed. The architecture includes a gateway (GW) coupled between a private IP network and a public IP network. A dynamic host configuration processor (DHCP) is operatively coupled to the GW. A network address translator (NAT) couples to the GW. Lastly, a processor, operatively coupled to the GW and the DHCP, is provided for dynamically assigning to a private IP network subscriber equipment an external IP address and a corresponding IP address hold time as a function of an application to be performed. Assignment of the external IP address and a corresponding IP address hold time is in response to a) a request for accessing the public IP network by a subscriber equipment of the private IP network to perform the application, or b) a request for accessing the private IP network by an entity of the public IP network. The external IP address is selected from a prescribed number of external IP addresses available to the private IP network.
