The present invention relates to a network device having an internet protocol address, and more particularly, to a method and apparatus for identifying a network device corresponding to an internet protocol address for device identification of a network device connected to a network.

1 is a diagram illustrating an example of network devices on a network connected by a wired or wireless LAN. As shown in FIG. 1, network devices such as a DVD player 12, a refrigerator 14, a computer 16, a television 18, and a printer 20 connected to a hub 10 each have a unique Internet protocol address. Has

The Internet protocol address is a 32-bit bit string that identifies an originator and a transmission line when communicating with TCP / IP. In general, every 8 bits (1 byte) are separated by periods and expressed as four decimal numbers. This address is divided into a network address and a computer address within the network.

Internet Protocol version 6 (IPv6) is the next generation of the 32-bit family of Internet Protocol version 4 (IPv4), which extends the Internet protocol address space to 128 bits, further expanding the network's scalability. It is an improvement. Internet Protocol Version Six is also known as Internet Protocol next generation (IPng). Internet Protocol Version Six allows all kinds of electronic devices such as DVD players 14, refrigerators 16, computers 18, televisions 20 and printers 22 to be connected to the Internet, as shown in Figure 1. Improved network scalability.

Internet Protocol Version Six assigns Internet Protocol addresses to allow network devices to connect to the Internet. The methods are stateful auto-configuration and stateless auto-configuration. ) There is a way.

Stateful autoconfiguration is a method of assigning an Internet protocol address from a dynamic host configuration protocol (DHCP) server. The dynamic host configuration protocol server is a communication protocol server for automatically allocating and managing configuration information necessary for executing TCP / IP communication. Stateless autoconfiguration is a method in which network devices themselves create and assign their own Internet protocol addresses.

Internet protocol addresses created using the stateless autoconfiguration method default to "FE80" or information received from a router, followed by the MAC address of the network device (MACA). . MAC address is the physical address of Ethernet. The size of a MAC address is 48 bits, and is usually written in a ROM on a network interface card (NIC) of a personal computer or a local area network (LAN) device. Used by specifying an address. For example, if the Mac address is "00: 50: DA: 89: D8: FC", the Internet protocol version six address created by the stateless autoconfiguration method is "fe80 :: 250: daff: fe89: d8fc. "Becomes.

However, the Internet protocol version Six address system uses a 128-bit address, so that the Internet protocol address of the network device that the user wants to use is memorized as if the address of the Internet protocol version format, which is the current 32-bit address system, is used. It is not easy to memorize. In addition, there is a problem that it is very difficult for a user to find network devices when the network device that the user wants to use does not have a protocol for device search (for example, Simple Network Management Protocol (SNMP)).

An object of the present invention is to provide a method for identifying a network device corresponding to an internet protocol address capable of identifying a network device having an internet protocol address corresponding to an IP version six.

Another object of the present invention is to provide an apparatus for identifying a network device corresponding to an internet protocol address capable of identifying a network device having an internet protocol address corresponding to an IP version six.

In order to achieve the above object, the identification method of the network device corresponding to the Internet protocol address according to the present invention comprises the steps of: searching for network devices connected to the network using a search message, Internet protocol addresses of the network devices in response to the search message Extracting the MAC addresses from the network device and using the database having the MAC addresses corresponding to each of the network device names and the network device names as the device identification information, respectively, the network device names corresponding to the extracted Mac addresses; Preferably, the step is to detect and display.

In order to achieve the above object, the apparatus for identifying a network device corresponding to the Internet protocol address according to the present invention is a device search for transmitting a search message for searching for network devices connected to a wired / wireless LAN to the network devices through the wired / wireless LAN. The data including the MAC address extraction unit for extracting MAC addresses from the Internet protocol addresses of the network devices responding to the search message, the MAC addresses corresponding to the network device names, and the network device names, respectively, as device identification information. Preferably, the base is configured with a network device name detection unit for detecting network device names corresponding to the extracted MAC addresses and a display unit for displaying network device names of the network devices.

Thirtieth to thirty-fourth steps).

First, the network devices connected to the network are searched using the search message (S30).

As shown in Fig. 1, an example is described with network devices such as a DVD player 12, a refrigerator 14, a computer 16, a television 18, a printer 20, and the like. When a user requests display for specific network devices by a host (not shown) connected to the hub 10 shown in FIG. 1, the DVD player 12, refrigerator 14, and computer 16 connected to the network are connected. , The search message is sent to the television 18, the printer 20, etc., to search for the network devices. The search message is, for example, for searching network devices connected to the hub 10 of FIG. 1, namely the DVD player 12, the refrigerator 14, the computer 16, the television 18, and the printer 20. Message. The discovery message is transmitted to all network devices in an all node multicast manner.

After the thirtieth step, MAC addresses are respectively extracted from the Internet protocol addresses of the network devices responding to the search message (step 32). Network devices responding to the search message are devices connected to a wired / wireless LAN to which a host is connected. Network devices that respond to the search message send to the host that sent the search message for their Internet protocol addresses.

The internet protocol addresses of network devices are those specified by the next generation communication protocol corresponding to the Internet protocol version six. Internet Protocol Version Six includes three types: unicast (one host to another host), anycast (one host to multiple hosts nearby), and multicast (one host to multiple hosts). It has rules about the type of address. Internet Protocol Versions Sixth is an extension of the header that allows you to specify mechanisms for authenticating packets, ensuring data integrity, and ensuring confidentiality.

In particular, the address assigned by the Internet Protocol Version Six is an Internet Protocol address assigned by the stateless autoconfiguration method of generating its own Internet Protocol address by the network device itself. The Internet protocol address assigned by the stateless autoconfiguration method includes the MAC address of each device. Thus, the host extracts the MAC addresses of the respective network devices from the received internet protocol addresses of the network devices.

For example, if the Internet protocol address received from a particular network device is "fe80 :: 2 50: daff: fe89: d8fc", then "00: 50: DA: corresponding to the MAC address of this network device from this protocol address. 89: D8: FC "is extracted.

After the thirty-second step, the network device names corresponding to the extracted MAC addresses are detected and displayed using a database including the network device names and the MAC addresses corresponding to each of the network device names as the device identification information. (Step 34). The device identification information has, as information, network device names connected to the network and MAC addresses corresponding to these network device names, respectively.

The network device name corresponding to the device identification information may include a device manufacturer name and a device product name. In other words, a device manufacturer name and a device product name corresponding to one network device are used as the network device name. The device identification has as its information respective MAC addresses corresponding to these network device names.

Accordingly, by using the device identification information, each network device name corresponding to the extracted MAC addresses can be detected by comparing the device identification information with the MAC addresses extracted in step 32.

When the network device names of the network devices are displayed, at least one or more of an internet protocol address, a device manufacturer company name, and a device product name corresponding to the network devices are displayed.
