Abstract
A client terminal reads a device ID fixedly assigned to itself, and sends the device ID to an authentication server to make a request for authentication. The authentication server authenticates the device ID accepted from the client terminal. When succeeding in the authentication, the authentication server issues and sends a ticket to the client terminal. The client terminal receives the ticket, and then sends the ticket to a locator server to make a request for registration of an IP address. The locator server verifies the correctness of the accepted ticket. When the correctness is confirmed, the locator server registers an ID and the IP address of the client terminal in a manner that they are associated with each other, and replies the completion of the registration.
