An information processing apparatus is selectively executable a normal mode or a sleep mode, the information processing apparatus including: a main controller circuit that operates in the normal mode; a sub controller circuit that operates in the sleep mode; a first communication interface capable of communicating with an external apparatus connected to a first network; and a second communication interface capable of communicating with a proxy response device, the proxy response device being unconnected to the first network. In the sleep mode, the sub controller circuit receives a request from the external apparatus via the first communication interface, sends the request to the proxy response device via the second communication interface, receives a response to the request from the proxy response device via the second communication interface, and sends the response to the external apparatus via the first communication interface.
