Kind Code:
B2
Abstract:
In a network where network address translation (NAT) has been introduced, a problem occurs in which, when an IP host operating in a network is automatically categorized with automatic IP host discovery using an ARP cache, a plurality of IP hosts with the same IP address are recognized as one IP host by NAT. To resolve this problem, a network management server specifies network sub-topology on the basis of topology information, public addresses translated by NAT, and IP host corresponding relationships.
