CONNECTION CONTROLLER FOR IP NETWORK WITH BUILT-IN DNS FUNCTION

摘要

PROBLEM TO BE SOLVED: To designate a party with a domain name and to enable communication without being conscious of an internet protocol(IP) address each other. SOLUTION: When the address of a terminal connected to a LAN is dynamically changed, an address survival time monitoring timer control part 1011 in an inter-LAN connector 1001 reports the change of the address to an IP address collation control part 1004 and a domain name system(DNS) server 1005 changes a DNS data base to be monitored so that the connection based on the domain name due to the DNS is enabled.
