ABSTRACT:
An apparatus is for setting a communication path between a communication terminal device connected through a first network and a plurality of second networks. The apparatus includes a name resolution request generator, a destination determiner, and a path setting unit. The name resolution request generator generates and transmits a name resolution request addressed to a name resolution server of the second networks, based on a name resolution request for name resolution of a destination received from the communication terminal device. The destination determiner assigns a priority to a name resolution response received from the name resolution server, and determines a destination based on the priority. The path setting unit sets a path by generating a routing table from path information including address information of the destination, address information of a gateway of the second networks, and an interface name.
