Abstract

A system includes electronic equipment, an information processing device and a server device. The electronic equipment sends first address change confirmation information containing first address information to the information processing device. The information processing device sends second address change confirmation information obtained by writing second address information in the received first address change confirmation information. The server device determines that the first address information and the second address information, which are contained in the received second address change confirmation information, agree with each other, and updates the address information to new one when the first address information and the second address information do not agree with each other. With such a system, electronic equipment can hold up-to-date address information of the information processing device with extremely light processing at the side of the server device and with small load of communication.
