Abstract
An inter-network connecting device is composed of two stages of a mask processing part (10) and a transmission control information generating part (30). The mask processing part (10) generates an address mask for extracting various address components from a destination address (IP) in a received message according to the destination address (IP). Thus, a process of extracting various address components such as a network address, a subnetwork address and the like from the destination address (IP) of a received message can be simplified.
