Abstract

An electronic device includes: a communication unit which communicates with an information server that stores predetermined information, a plurality of address-offering servers that store IP addresses existing in a network and provide any one of the stored IP addresses, and a management server that includes area information on the network where the information server is located; and a controller which performs a request for an IP address of the information server for the use of information stored in the information server from the plurality of address-offering servers and the management server, checks whether the provided IP address can be used to the plurality of the address-offering servers and the management servers if one of the plurality of address-offering servers provides the IP address of the information server, and controls the communication unit to receive the information from the information server based on the IP address if a positive response signal for the use of the IP address is received from the management server.

Claims

1. An electronic device comprising:

a communication unit which performs communication with an information server that stores predetermined information, a plurality of address-offering servers that store IP addresses existing in a network and provide any one of the stored IP addresses, and a management server that includes area information on the network where the information server is located; and

a controller which performs a request for an IP address of the information server for the use of information stored in the information server from the plurality of address-offering servers and the management server, checks whether the provided IP address can be used to the plurality of the address-offering servers and the management servers if one of the plurality of address-offering servers provides the IP address of the information server, and controls the communication unit to receive the information from the information server by utilizing the IP address if a positive response signal for the use of the IP address is received from the management server.

2. The electronic device of claim 1, wherein, if a negative response signal for the use of the IP address is received from the management server, the controller re-requests the IP address of the information server for the use of the information stored in the information server from the plurality of address-offering servers and the management server.

3. The electronic device of claim 1, wherein the information stored in the information server comprises booting information for booting the electronic device.

4. The electronic device of claim 1, wherein the controller controls the communication unit to broadcast the request for the IP address and the information on whether the provided IP address can be used.

5. The electronic device of claim 1, further comprising a display unit for displaying an image.

6. A control method of an electronic device, the control method comprising:

requesting an IP address of an information server for the use of information stored in the information server from a plurality of address-offering servers that store IP addresses in a network and provide any one of the stored IP addresses, and a management server that includes area information on the network where the information server is located;

checking whether the IP address of the information server is provided from one of the plurality of address-offering addresses in response to the request;

informing the plurality of address-offering servers and the management server whether the provided IP address can be used when the IP address is provided,; and

communicating with the information server based on the IP address if a positive response signal for the use of the IP address is transmitted from the management server.

7. The control method of claim 6, wherein the requesting of the IP address of the information server for using information stored in the information server from the plurality of address-offering servers and the management server is repeated if a negative response signal for the use of the IP address is received from the management server.

8. The control method of claim 6, wherein the information stored in the information server comprises booting information for booting the electronic device.

9. The control method of claim 6, wherein the requesting of the IP address and the informing of whether the provided IP address can be used are broadcasted.

10. A management server comprising:

a communication unit which communicates with an electronic device located in a network where the management server is located;

a storage unit which stores area information on a network where an information server storing predetermined information is located; and

a controller which controls the communication unit to transmits a positive response signal to the electronic device if an IP address is included in the area information stored in the storage unit when the electronic device receives the IP address from one of a plurality of address-offering servers providing IP addresses, and checks whether the IP address can be used.

11. The control method of claim 10, wherein the controller controls the communication unit to transmit a negative response signal if the IP address informed from the electronic device is not included in the area information stored in the storage unit.

12. A control method of a management server, the control method comprising:

receiving an IP address provided by one of a plurality of address-offering servers providing IP addresses and checking whether the IP address can be used by an electronic device;

checking whether the IP address is included in area information on a network where an information server storing predetermined information is located; and

transmitting a positive response signal to the electronic device if the IP address is included in the area information.

13. The control method of claim 12, further comprising transmitting a negative response message to the electronic device if the IP address informed by the electronic device is not included in the area information stored in the storage unit.
