Electronic device, IP address determining method, and recording medium having IP address determining program stored therein

An IP address determining method that generates an interface identifier to determine an IP address of an electronic device, comprising:

• an interface identifier generating step of generating the interface identifier;
• a temporary IP address determining step of determining a temporary IP address containing the interface identifier generated in the interface identifier generating step and a prefix;
• a duplication determining step of determining whether the temporary IP address determined in the temporary IP address determining step is the same as an IP address of another electronic device;
• and
• an IP address determining step of specifying the temporary IP address as the IP address of the electronic device, when it is determined in the duplication determining step that the temporary IP address is not the same as the IP address of said another electronic device;
• wherein another interface identifier is generated in the interface identifier generating step when it is determined in the duplication determining step that the temporary IP address is the same as the IP address of said another electronic device.

A recording medium having an IP address determining program stored therein for generating an interface identifier to determine an IP address of an electronic deice, the program causing a computer to execute:

• an interface identifier generating process of generating the interface identifier;
• a temporary IP address determining process of determining a temporary IP address containing the interface identifier generated in the interface identifier generating process and a prefix;
• a duplication determining process of determining whether the temporary IP address determined in the temporary IP address determining process is the same as an IP address of another electronic device;
• and
• an IP address determining process of specifying the temporary IP address as the IP address of the electronic device, when it is determined in the duplication determining process that the temporary IP address is not the same as the IP address of said another electronic device;
• wherein another interface identifier is generated in the interface identifier generating process when it is determined in the duplication determining process that the temporary IP address is the same as the IP address of said another electronic device.
