Patent ID: 8386603

Claim:
An information processing terminal device including a plurality of communication interfaces connectable to networks, said information processing terminal device comprising: a plurality of communication interfaces that request connection to networks different from each other and obtain, from Dynamic Host Configuration Protocol (DHCP) servers corresponding to the respective networks, connection information that includes Internet Protocol (IP) addresses and is necessary for the connection to the networks; an IP address scheme determination unit configured to determine whether or not the IP addresses that are included in the connection information obtained by two of said communication interfaces are IP addresses having the same address scheme; and a connection information setting unit configured to: (i) set, for only one of said two communication interfaces, a corresponding one of the IP addresses when said IP address scheme determination unit determines that the IP addresses that are included in the connection information obtained by said two communication interfaces are the IP addresses having the same address scheme, and in the case where one of said two communication interfaces is a communication interface defined as a LAN interface, (ii) set, for said LAN interface, neither gateway information nor Domain Name System (DNS) server information that is necessary for said LAN interface to connect to an external server and is included in the connection information for said LAN interface, even when said IP address scheme determination unit determines that the IP addresses that are included in the connection information obtained by said two communication interfaces are the IP addresses having different address schemes.
