An information processing apparatus communicates within a system by using identification information for identifying a device includes, a first device in which a first identifier is uniquely set, a holding part that holds a second identifier settable arbitrarily for a device in the system, an acquiring part that acquires identification information corresponding to a second device connected in the system and is different from the first device, a determining part that determines whether the second identifier to be set for the first device is used in the system as the identification information based on the identification information corresponding to the second device acquired by the acquiring part and the second identifier held in the holding part, and a setting part that sets the second identifier as the identification information of the first device based on the determination by that the second identifier is not used in the system.
