Abstract
In a system having two or more gateway apparatuses connected to both first and second networks having mutually different address systems, a gateway apparatus is provided with a translation table for associating IP addresses with node IDs. The gateway apparatus inquires other gateway apparatuses whether other gateway apparatuses are administering the same address as an IP address generated for a newly added device. If there is another gateway apparatus that is administering the same address, the IP address is prevented from being registered in the translation table.
