ABSTRACT:
To connect arbitrary network communication apparatuses by selecting an appropriate route or identifying an IP address in an environment which includes a network using plural NAT routers, which is hierachically connected through plural NAT routers for distributing private IPs. A network communication apparatus includes: a direct search unit which transmits a direct search request to another network communication apparatus; a route information obtaining unit which obtains route information of the network communication apparatus from a server which holds the route information of the network communication apparatus; and a communication control unit which performs, when the information regarding the other network communication apparatus is obtained upon the direct search request, communication with the other network communication apparatus based on the information, and which performs, when the information is not obtained, communication with the other network communication apparatus, based on the route information.
