An image processing apparatus is provided with a terminal designation accepting portion that accepts a designation by a user to designate an IP address of a terminal to be connected to the image processing apparatus and a setting data control portion that sends, to the terminal, setting data that includes an IP address of the image processing apparatus itself based on the IP address of the terminal that is designated by the user. Thereby, in the case where the image processing apparatus is caused to cooperate with other apparatus via a communication line, a more user-friendly operation for the cooperation can be provided with the security of the image processing apparatus protected compared to conventional systems.
