Abstract:
1. A network modem device, comprising: an integrated mechanism operative as a first dynamic address assignment server for dynamically assigning network addresses on a network; a controller circuit operative to detect a presence of a second dynamic address assignment server on the network; an interrupter operative to send a disable signal to the integrated mechanism for disabling the integrated mechanism in response to the detection of the presence of the second dynamic address assignment server on the network by the controller circuit, the interrupter being further operative otherwise to allow the integrated mechanism to dynamically assign network addresses on the network; and a memory store for storing unknown used addresses, wherein the integrated mechanism comprises a start-up mechanism for checking availability of addresses on the network and for placing used addresses in the memory store of unknown used addresses, and an address manager for selecting new addresses not included in the store of unknown used addresses and for removing addresses from the store of unknown used addresses when a client having one of the addresses in the store of unknown used addresses requests a dynamically assigned address.
