An information processing device includes a communication unit, a storage unit, and a processor. The communication unit is connected to a network. The storage unit stores environment setting information indicating the environment of the device. The information is set according to the type of the network and the presence or absence of a virtual network created through the network. The processor sets the environment of the device based on the environment setting information in at least one of the following cases: when the network is switched to another network and when the presence or absence of the virtual network is changed.
