ABSTRACT:
An address-translating connection device which makes it possible to dynamically assign an IP address to a private address when a connection is made to inside of a LAN from outside. When an inquiry made by designating a host name as to a global address of the same is received from the first network, a private address-retrieving device looks up a host-name/private-address correlation storage device to retrieve a private address correlated to the designated host name. When a determining device determines that the address-correlation storage/translation device does not store a global address correlated to the retrieved private address, a storage device extracts an available one of global addresses to correlate the available global address to the retrieved private address, and cause the address-correlation storage/translation device to store therein the addresses correlated to each other. At the same time, a first notifying device sends out into the first network a reply notifying the global address stored.
