Abstract

An equipment managing device includes a first address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device so as to obtain an IP address of the equipment item; a second address obtaining part configured to obtain an IP address of another equipment item from each of plural of the equipment items searched for the first address obtaining part; an address generating part configured to generate a subnet address of a network different from at least the equipment managing device; and a searching part configured to search for equipment connecting to the network different from at least the equipment managing device.

Claims

1. An equipment managing device configured to manage equipment connected to a network, comprising:

an address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device and configured to obtain an IP address of another equipment item from each of plural of the searched equipment items, the IP address of the other equipment item being held by the corresponding searched equipment item for communicating with the other equipment item;

an address information generating part configured to generate address information of a network different from at least the equipment managing device, based on gathering the IP addresses obtained by the address obtaining part; and

a searching part configured to search for equipment connecting to the network different from at least the equipment managing device, based on the address information generated by the address information generating part.

2. An equipment managing device configured to manage equipment connected to a network, comprising:

an address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device and configured to obtain an IP address of another equipment item from each of plural of the searched equipment items, the IP address of the other equipment item being held by the corresponding searched equipment item for communicating with the other equipment item;

an address generating part configured to generate a subnet address of a network different from at least the equipment managing device, based on gathering the IP addresses obtained by the address obtaining part; and

a searching part configured to search for equipment connecting to the network different from at least the equipment managing device, based on the subnet address generated by the address generating part.

3. An equipment managing device configured to manage equipment connected to a network, comprising:

a first address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device so as to obtain an IP address of the equipment item;

a second address obtaining part configured to obtain an IP address of another equipment item from each of plural of the equipment items searched for the first address obtaining part, the IP address of the other equipment item being held by the corresponding equipment item searched for by the first address obtaining part for communicating with the other equipment item;

an address generating part configured to generate a subnet address of a network different from at least the equipment managing device, based on gathering the IP addresses obtained by the second address obtaining part; and

a searching part configured to search for equipment connecting to the network different from at least the equipment managing device, based on the subnet address generated by the address generating part.

4. The equipment managing device as claimed in claim 3,

wherein the first address obtaining part and the second address obtaining part periodically obtain the IP addresses.

5. The equipment managing device as claimed in claim 3,

wherein the searching part issues a broadcast using a broadcast address of the subnet address based on the subnet address generated by the address generating part so as to search for the equipment connecting to the network different from at least the equipment managing device.

6. The equipment managing device as claimed in claim 4,

wherein the searching part issues a broadcast using a broadcast address of the subnet address based on the subnet address generated by the address generating part so as to search for the equipment connecting to the network different from at least the equipment managing device.

7. The equipment managing device as claimed in claim 3,

wherein the searching part queries each of IP addresses included in a range between a minimum value and a maximum value of the IP addresses of the subnet address based on the subnet address generated by the address generating part so as to search for the equipment connecting to the network different from at least the equipment managing device.

8. The equipment managing device as claimed in claim 4,

wherein the searching part queries each of IP addresses included in a range between a minimum value and a maximum value of the IP addresses of the subnet address based on the subnet address generated by the address generating part so as to search for the equipment connecting to the network different from at least the equipment managing device.

9. An equipment searching program configured to make a computer function as each of parts of an equipment managing device, the equipment managing device comprising:

a first address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device so as to obtain an IP address of the equipment item;

a second address obtaining part configured to obtain an IP address of another equipment item from each of plural of the equipment items searched for the first address obtaining part, the IP address of the other equipment item being held by the corresponding equipment item searched for by the first address obtaining part for communicating with the other equipment item;

an address generating part configured to generate a subnet address of a network different from at least the equipment managing device, based on gathering the IP addresses obtained by the second address obtaining part; and

a searching part configured to search for equipment connecting to the network different from at least the equipment managing device, based on the subnet address generated by the address generating part.

10. A computer readable recording medium including an equipment searching program, the equipment searching program being configured to make a computer function as each of parts of an equipment managing device, the equipment managing device comprising:

a first address obtaining part configured to search for an equipment item connected to the same network as the equipment managing device so as to obtain an IP address of the equipment item;

a second address obtaining part configured to obtain an IP address of another equipment item from each of plural of the equipment items searched for the first address obtaining part, the IP address of the other equipment item being held by the corresponding equipment item searched for by the first address obtaining part for communicating with the other equipment item;

an address generating part configured to generate a subnet address of a network different from at least the equipment managing device, based on gathering the IP addresses obtained by the second address obtaining part; and

a searching part configured to search for equipment connecting to the network different from at least the equipment managing device, based on the subnet address generated by the address generating part.
