<p>PROBLEM TO BE SOLVED: To provide a method that simply connects a client operation terminal and a network device, and establishes connection and communication with a dynamic DNS service server and a client device without requiring complicated input work.SOLUTION: A client operation terminal 1 images and scans an image 3 into which network device specific information is embodied, creates a host name for inquiry, and then transmits it to a dynamic DNS service server 4. The server checks it with a held or generated unique host name, and transmits a corresponding global IP address to the client operation terminal. The client operation terminal transmits login information held or generated from the image to a network device corresponding to the global IP address, permits communication after connection authentication processing, and thus it connects the network device comprising a dynamically changeable global IP address and the client operation terminal on the Internet and enables communication.</p> |
