    • An information communication system for exchanging a plurality of contents between a plurality of node devices, includes a plurality of internal networks connected to an external network. The internal networks include: the plurality of node devices connecting the same internal network; and a support device, which connects the internal networks, and which supports acquisition of contents by the node devices. An overlay network allows for exchanging of contents between the node devices and the support devices. The node devices include a first acquisition unit that acquires contents by selecting a first device group in preference to a second device group. The first device group includes: a support device and a node device connecting the internal network of an access destination that is a contents acquisition destination. The second device group includes a support device and a node device that do not connect the internal network of the access destination.
