1. A network system for transferring a packet, comprising:
a first network that controls transfer of data at a first layer;
a second network that is connected to the first network and controls transfer of data at the first layer while managing devices in the second network at a second layer different from the first layer;
a device that is connected to the first network but disconnected from the second network; and
a processor programmed to translate addresses between the first network and the second network,
wherein the processor accepts a configuration including a type of an address of the second layer of the second network and translates an address of the first layer of the first network attached to data transferred from the first network to the second network into the address of the second layer, which is a same type as the type of the configuration, based on address translation information that holds a correspondence relationship between the address of the first network and the address of the second network, to produce a translated address, and
wherein the device communicates with the second network via the processor based on the translated address.
