Abstract
A system and method is described for centrally managing private computer networks, each of which has a network element assigned the identical IP address. The networks are mapped into domains which each contains only network elements that have unique IP addresses. A separate virtual or physical interface at a management station is associated with each domain whereby management data is exchanged between the management station and a particular domain through a domain-specific interface that is assigned its own IP address. This IP address is inserted as the source address in data transmitted from the management station to the associated domain, thereby enabling a router to discern the domain to which the data should be routed. This IP address is also inserted as a destination address in data transmitted from a domain to the management station, thereby enabling the management station to discern from which domain the received data originated.
