Abstract

Provided are a method and apparatus for identifying a network device corresponding to an Internet protocol address. The method comprises the steps of detecting network devices over a network using a detection message, extracting media access control addresses from Internet protocol addresses of network devices which respond to the detection message, and detecting and displaying names of network devices corresponding to the extracted media access control addresses from a database which stores device identification information specifying names of network devices and media access control addresses corresponding to the respective names.

Claims

1. A method for identifying a network device corresponding to an Internet protocol address, comprising the steps of:

(a) detecting network devices over a network using a detection message;

(b) extracting media access control addresses from Internet protocol addresses of the network devices which respond to the detection message; and

(c) detecting and displaying the names of network devices corresponding to the extracted media access control addresses by matching the extracted media access control addresses with device identification information in a database which stores device identification information specifying names of network devices and media access control addresses corresponding to the respective names,

wherein the Internet protocol addresses are determined according to added information of Internet protocol version 6.

2. The method of claim 1, wherein the names of each of the network devices stored in the database comprises a manufacturer name and product name of each of the network devices.

3. The method of claim 2, wherein during step (c), at least one of the Internet protocol address, manufacturer name, and product name of each of the network devices is displayed.

4. An apparatus for identifying a network device corresponding to an Internet protocol address, comprising:

a device detecting unit for transmitting a detection message to network devices connected to a wired or wireless local area network via the wired or wireless local network area, the detection message allowing detection of the network devices;

a media access control address extracting unit for extracting media access control addresses from Internet protocol addresses of network devices which respond to the detection message, respectively;

a network device name detecting unit for detecting the names of network devices corresponding to the extracted media access control addresses by matching the extracted media access control addresses with device identification information in a database storing device identification information, which specifies names of network devices and media access control addresses corresponding to the respective names; and

a displaying unit for displaying the detected names of network devices,

wherein the Internet protocol addresses are determined according to added information of Internet protocol version 6.

5. The apparatus of claim 4, wherein the names of each of the network devices stored in the database comprises a manufacturer name and product name of each of the network devices.

6. The apparatus of claim 5, wherein when displaying the names of network devices, the display displays at least one of the Internet protocol address, manufacturer name, and product name of each of the network devices.

7. The apparatus of claim 4, wherein the apparatus is installed in one of a host, an image forming apparatus, and a server connected to the wire/wireless local area network.

8. The apparatus of claim 7, wherein the database is installed in one of the host, the image forming apparatus, and the server connected to the wire/wireless local area network.

9. The apparatus of claim 4, wherein the database is installed in a server connected to the wired or wireless local area network.

10. A method for allocating an Internet protocol address to a network device, comprising the steps of:

(a) setting a device type code and a maximum number of network devices that can be allocated with Internet protocol addresses according to the types of network devices;

(b) receiving media access control addresses and the types of network devices and creating an Internet protocol address for each of the network devices using a related device type code;

(c) matching the media access control addresses of the network devices with the created Internet protocol addresses, respectively; and

(d) allocating a particular network device an Internet protocol address corresponding to the media access control address of the particular network device in response to a request for allocation of an Internet protocol address to the particular network device,

wherein the Internet protocol addresses are determined according to added information of Internet protocol version 6.

11. The method of claim 10, wherein during step (b), a number that is smaller than or equal to the maximum number is included in each of the created Internet protocol addresses.

12. An apparatus for allocating an Internet protocol address to a network device, comprising:

a device information setting unit for setting a device type code and a maximum number of network devices that can be allocated with Internet protocol addresses according to the types of network devices;

an address creating unit for receiving media access control addresses and the types of network devices and creating an Internet protocol address of each of the network devices using a relating device type code;

a media access control address matching unit for matching the media access control addresses of the network devices with the created Internet protocol addresses, respectively; and

an address allocating unit for allocating to a particular network device an Internet protocol address corresponding to the media access control address of the particular network device in response to a request for allocation of an Internet protocol address to the particular network device,

wherein the Internet protocol addresses are determined according to added information of Internet protocol version 6.

13. The apparatus of claim 12, wherein the address creating unit inserts a number that is smaller than or equal to the maximum number of network devices into each of the created Internet protocol address.
