INTER-NETWORK COMMUNICATING METHOD, NOTIFICATION DEVICE, PROGRAM, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To perform such inter-network communication as first communication apparatus in a first network accesses a second communication apparatus in a second network, and the second communication apparatus makes the first communication apparatus access a third communication apparatus in the first network determined by the second communication apparatus without notifying the first communication apparatus of an address assigned individually to the third communication apparatus.

SOLUTION: An address mapping table for associating a first address assigned every communication apparatus in a first network with a second address, i.e., the address information in a second network, is stored in a communication apparatus. The communication apparatus searches the address mapping table by using a second address that is input, and extracts a first address associated with the second address. Subsequently, a second communication apparatus in the second network transmits second information including the first address thus extracted through the second network.
