Abstract
A determining unit determines whether a second bit string that forms an Internet Protocol Version 4 (IPv4) address is included in a first bit string that forms an address for Internet Protocol Version 6 (IPv6) connection, and further determines whether the address for IPv6 connection is an extended address extended to an address length of an IPv6 address by adding a prior determined bit to the IPv4 address, when the second bit string is determined to be included in the first bit string. A changing unit changes a priority of the address for IPv6 connection that is determined as the extended IPv6 address. A selecting unit selects preferentially a high level address for IPv6 connection during establishing connection with an external communication apparatus.
