At this time, the connection information acquisition unit 120 transmits a DNS Request message requesting the management apparatus 400 to request the management apparatus first connection information (e.g., management apparatus 3G IP) corresponding to the first network (e.g., 3G) To the first network device 200, and can request it.

Accordingly, the first network device 200 requests the address assigning apparatus 700 for the management apparatus first connection information (e.g., management apparatus 3G IP) in response to a request from the terminal apparatus 100. [ At this time, the first network device 200 transmits a DNS query message to the management device 400 requesting the management device first connection information (e.g., management device 3G IP) corresponding to the first network (e.g., 3G) To the address assignment apparatus 700, and can make a request.
