ABSTRACT:
A transmitter router search apparatus26transmits an inspection IP packet to an inspection target network connection apparatus via an intranet10. The source and destination IP addresses of the inspection IP packet are designated respectively as the IP addresses of a recipient router search apparatus28and the inspection target network connection apparatus. A TCP packet, including predetermined ID information, is included in the data portion. The inspection target network connection apparatus generates an IP packet corresponding to the received inspection IP packet. Since the transmission source and destination of the response IP packet are respectively designated the transmission destination and source of the inspection IP packet, the recipient router search apparatus28receives the response IP packet via the Internet19, so long as the inspection target network connection apparatus is a router.
