Abstract

Maintaining a current network address between a network device and a network management system (NMS) that enables central configuration control over a number of network devices. Network devices with dynamically changeable network addresses provide address updates to a listener system, which maintains a database of current IP addresses relative to device names. The network devices communicate with the listener system via a listener network address and a first predefined port. The NMS submits a device name to the listener system in a request for a current network address via a second predefined port. The listener system optionally checks a local hosts file and/or DNS server before resolving a current network address from the device name associated with a unique MAC address. The listener system provides the NMS with the current network address when requested by the NMS or immediately if the NMS registers for immediate notification of an address change.
