Abstract: An information processing device includes storage and a controller. In a case where a change of network address occurs in a communication channel, the storage stores a pre-change network address for a terminal connected to the communication channel in association with a post-change network address for a terminal whose network address has changed. In a case where communication to a terminal is performed using the pre-change network address, the controller controls the communication by using the storage such that, in a case where the network address of the terminal has not changed, the communication is performed as-is, whereas in a case where the network address of the terminal has changed, the pre-change network address is converted to the post-change network address to communicate with the terminal.
