Abstract
In order to prevent unnecessary APIPA process from being executed in a LAN environment which does not adopt APIPA, an ICMP echo request for a predetermined IP address is broadcast. Whether there are more than N apparatuses using APIPA is checked based on the replies, and if there are, IP address setting by APIPA is executed. In a LAN environment which adopts APIPA, whether the IP address to be assigned to an apparatus is already being used by another apparatus is checked. If the date and time when the other apparatus was assigned the IP address is earlier than the date and time when the apparatus was assigned the IP address, APIPA is executed to decide the IP address of the apparatus.
Claims27
An address setting apparatus for assigning an address to a device in a network having a plurality of devices connected to the network via a network interface, the address setting apparatus comprising:
- a display device that displays a list of device information to a user;
- an input device that allows the user to input a new address to be set to a corresponding device based on the displayed list of device information;
- and
- a controller configured to acquire an address set to each of the plurality of devices connected to the network via the network interface and to generate the list of device information that includes devices that have an acquired address that is a default address of the device or devices that have an acquired address that is an address different from the network to which the address setting apparatus belongs, and wherein the controller:
- displays the generated list of device information on the display device;
- and
- transmits the new address input by the user via the input device, based on the generated list of device information, to the corresponding device via the network interface as an address to be set to the corresponding device.
A non-transitory computer-readable storage medium encoded with a program for enabling a computer to function as an address setting apparatus for assigning an address to a device in a network having a plurality of devices connected to the network via a network interface, the program comprising the steps of:
- acquiring an address set to each of the plurality of devices connected to the network via the network interface;
- generating a list of device information that includes devices that have an acquired address that is a default address of the device or devices that have an acquired address that is an address different from the network to which the address setting apparatus belongs;
- displaying the generated list of device information on a display device;
- allowing, by an input device, a user to input a new address to be set to a corresponding device based on the generated list of device information;
- and
- transmitting the new address input by the user via the input device, based on the generated list of device information, to the corresponding device via the network interface as an address to be set to the corresponding device.
A method for assigning an address to a device in a network having a plurality of devices connected to the network via a network interface, the method comprising the steps of:
- acquiring, with a controller, an address set to each of the plurality of devices connected to the network via the network interface;
- generating a list of device information that includes devices that have an acquired address that is a default address of the device or devices that have an acquired address that is an address different from the network to which the address setting apparatus belongs;
- displaying, with the controller, the generated list of device information on a display device;
- allowing a user to input a new address to be set to a corresponding device based on the generated list of device information via an input device;
- transmitting, with the controller, the new address input by the user via the input device, based on the generated list of device, information, to the corresponding device via the network interface as an address to be set to the corresponding device.
