Node device, information communication method and computer readable recording medium

A non-transitory computer readable recording medium storing a program causing a computer of a node device to execute:

• determining whether or not the node device is communicable over IPv4 (Internet Protocol Version 4);
• determining whether or not the node device is communicable over IPv6 (Internet Protocol Version 6);
• and
• acquiring one of a first routing table that is generated using information of a first node device communicable over the IPv4 and a second routing table that is generated using information of a second node device communicable over the IPv6 from a predetermined device via a network according to a predetermined priority order in response to determining that communication is possible over the IPv4 and determining that communication is possible over the IPv6,
• controlling transmitting and receiving of a message for controlling a communication system using the acquired one of the first routing table and the second routing table;
• and
• receiving at least one of a first message that is sent or received using the first routing table and a second message that is sent or received using the second routing table, wherein in response to determining that communication is possible over the IPv4 and determining that communication is possible over the IPv6, preventing performing the transmission of the message which is received using a different routing table from the determined routing table between the first routing table and the second routing table.

An information communication method, comprising:

• determining whether or not the node a first node device is communicable over IPv4 (Internet Protocol Version 4);
• determining whether or not the node a second node device is communicable over IPv6 (Internet Protocol Version 6);
• and
• acquiring one of a first routing table that is generated using information of a first node device communicable over the IPv4 and a second routing table that is generated using information of the second node device communicable over the IPv6 from a predetermined device via a network according to a predetermined priority order in response to determining that communication is possible over the IPv4 and determining that communication is possible over the IPv6,
• controlling transmitting and receiving of a message for controlling a communication system using the acquired one of the first routing table and the second routing table;
• and
• receiving at least one of a first message that is sent or received using the first routing table and a second message that is sent or received using the second routing table, wherein in response to determining that communication is possible over the IPv4 and determining that communication is possible over the IPv6, preventing performing the transmission of the message which is received using a different routing table from the determined routing table between the first routing table and the second routing table.
