NETWORK SYSTEM CAPABLE OF ACCESSING TERMINAL FOR ACQUIRING DYNAMIC NW ADDRESS, ACCESS METHOD, AND GATEWAY

摘要

PROBLEM TO BE SOLVED: To allow a first terminal connected to a gateway to be accessed without consciousness of a network address or the like by information easier to handle.;SOLUTION: In the network system including a second terminal accessible to the first terminal and the gateway, the gateway includes: a means for dynamically generating a network address to the first terminal; a delivery database for storing a correspondence relation between the network address of the first terminal and a MAC address; a means for generating a domain name including the MAC address of the first terminal, a DNS database for storing a correspondence relation between the domain name and the network address; and a DNS server means for returning the network address corresponding to the domain name to the second terminal when receiving a resolution request of the domain name from the second terminal. The second terminal uses the returned network address to access the first terminal.;COPYRIGHT: (C)2008,JPO&INPIT
