The present invention relates to a dynamic host configuration communication protocol server for allocating an Internet protocol address to a network device. More particularly, the present invention relates to an Internet protocol address for allocating an Internet protocol address into which an Internet protocol address is inserted. A method and apparatus for allocating an Internet protocol address.

1 is a diagram illustrating an example of network devices and a dynamic host configuration communication protocol server connected on a network. 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, each connected to a hub 10, each have its own Internet protocol. Has an address.

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). The Internet Protocol Version Six allows all kinds of electronic devices such as DVD players 12, refrigerators 14, computers 16, televisions 18 and printers 20 to connect to the Internet as shown in Figure 1. Improved network scalability.

Internet Protocol Version Six assigns an Internet Protocol address to allow network devices to access the Internet. ) There is a way.

Stateless autoconfiguration is a method in which network devices themselves create and assign their own Internet protocol addresses.

Stateful autoconfiguration is a method of assigning an Internet protocol address from a dynamic host configuration protocol (DHCP) server. As shown in Fig. 1, the dynamic host setting protocol server 22 is a communication protocol server for automatically allocating and managing setting information necessary for executing TCP / IP communication. Referring to the method of assigning the Internet protocol address by the dynamic host configuration protocol server 22, first, the network device requests the dynamic host configuration protocol server 22 to allocate the Internet protocol address. The dynamic host setting protocol protocol server 22 then looks at the MAC address of the network device and assigns an Internet protocol address predetermined by the network administrator. The network device provided with the assigned Internet Protocol address sets the assigned Internet Protocol address as its Internet Protocol address.

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)).

Therefore, there is a problem in that it is impossible to distinguish what kind of network device the report is based on only the assigned Internet protocol address.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide a method for allocating an Internet protocol address, which allows a report of only the assigned Internet protocol address to distinguish which kind of network device.

Another object of the present invention is to provide an apparatus for allocating an internet protocol address, which can distinguish which kind of network device a report of only an allocated internet protocol address is.

In order to achieve the above object, the Internet protocol address allocation method according to the present invention comprises the steps of setting the device type code and the maximum number of allocating device for each device type of network devices, by receiving the MAC address and network device type of each network device Generating an internet protocol address of each of the network devices using a device type code, matching a MAC address of each of the network devices with each generated internet protocol address, and requesting an allocation of an internet protocol address for a specific network device According to the present invention, the step of assigning a specific Internet protocol address corresponding to the MAC address of the specific network device is preferable.

In order to achieve the above object, the Internet protocol address allocating apparatus according to the present invention includes a device information setting unit for setting a device type code and a maximum number of allocating devices for each device type of the network devices, the MAC addresses of the network devices, and the network devices An address generator for generating Internet protocol addresses of each of the network devices by using the device type code, a MAC address matching unit for matching MAC addresses of each of the network devices with the generated Internet protocol addresses, and a specific network. In response to a request for allocating an Internet protocol address for a device, the device may be configured as an address allocator for allocating a specific Internet protocol address corresponding to a MAC address of a specific network device.

Hereinafter, an internet protocol address allocation method according to the present invention will be described with reference to the accompanying drawings.

Figure 2 is a flowchart of one embodiment for explaining the Internet protocol address allocation method according to the present invention.

First, a device type code and a maximum assigned device number are set for each device type of each network device (step 100). The network administrator configures an Internet protocol pool on a dynamic host configuration protocol (DHCP) server. That is, a device type code for distinguishing types of network devices is set, and a maximum allocating device number indicating a number to which network devices corresponding to the device type code can be allocated to the maximum is set.

3 is a diagram illustrating an example of an input window displayed for inputting a device type code and a maximum assigned device number. As shown in FIG. 3, the network manager may select a type of a network device through the displayed input window and input a device type code and a maximum number of allocated devices. The network device "TV" selected by the network administrator has a code value of binary "1001" as the device type code, and the maximum number of Internet protocol addresses that can be allocated to "TV" is up to "100". It can be seen that it is limited to.

After operation 100, the MAC device receives a MAC (Media Access Control) address and a network device type of each network device, and generates an internet protocol address of each network device using a device type code (step 102). When the MAC address and the network device type of each of the network devices are input by the network administrator, an Internet protocol address including a device type code corresponding to the input network device type is generated.

4 is a diagram illustrating an example of an input window displayed for inputting a MAC address and a network device type of each network device. The network manager inputs a device type of each of the network devices and a MAC address of the network devices through an input window as shown in FIG. 4. The MAC address is a physical address on an Ethernet, which means an address of a local area network (LAN) of a network device. As shown in Fig. 4, it indicates that the MAC address "000F0A01234" for the network device corresponding to "TV" has been input.

As such, when the MAC address and the network device type of each network device are input, an internet protocol address including a device type code corresponding to the input network device type is generated. For example, if the network device type is "TV", an internet protocol address is generated using "1001" corresponding to the device type code corresponding to "TV".

On the other hand, when generating the Internet protocol address, characterized in that the Internet protocol address includes the numeric information within the maximum number of allocated devices set in step 100. For example, if the network device type is "TV" and the maximum allocator number corresponding to the maximum number of Internet protocol addresses that can be allocated for "TV" is "100", the number included in the Internet protocol address. The information should be numeric information within "100". This indicates that the number of "TVs" that can be assigned as Internet protocol addresses is limited to within "100".

5 is an example diagram illustrating a structure of an Internet protocol address according to the present invention. As shown in Fig. 5, the Internet protocol address according to the present invention includes a device type code in binary and a maximum assigned device number as part of the 128-bit address information in the Internet protocol address.

After step 102, the MAC address of each of the network devices is matched with each generated Internet protocol address (step 104). Since each of the Internet protocol addresses generated in step 102 is generated based on the input MAC address and the type of network device, each of the generated Internet protocol addresses must correspond to each input MAC address. Therefore, each generated Internet protocol address matches each input MAC address.

After step 104, a specific Internet protocol address corresponding to the MAC address of the specific network device is allocated according to the request for assigning the Internet protocol address to the specific network device (step 106). If there is a request for the assignment of the Internet protocol address for the specific network device from the user of the specific network device, the Internet protocol addresses in step 104 by referring to the specific MAC address of the specific network device sent together with the request for assignment of the Internet protocol address It checks if there is a specific MAC address among the matching MAC addresses. If there is a specific MAC address among the matched MAC addresses, the specific Internet protocol address matched with the specific MAC address is assigned as the Internet protocol address of the specific network device.

Thus, when a specific Internet protocol address is assigned and transmitted to a specific network device, the specific network device sets the received specific Internet protocol address as its Internet protocol address.

The user can confirm the Internet protocol address of the network device by checking the device type code included in the set Internet protocol address.

Hereinafter, an apparatus for allocating an Internet protocol address according to the present invention will be described with reference to the accompanying drawings.

Figure 6 is a block diagram of an embodiment for explaining the Internet protocol address allocation apparatus according to the present invention, the device information setting unit 200, address generation unit 210, MAC address matching unit 220 and address allocator ( 230). The device information setting unit 200, the address generating unit 210, the MAC address matching unit 220, and the address allocating unit 230 are provided in the dynamic host setting communication protocol server 22.

When the device information setting unit 200 receives a device type code and a maximum allocation device number of the network devices through the input terminal IN1 from the network administrator, the device information setting unit 200 sets the Internet protocol pool using the device type code and the maximum allocation device number. Then, the set result is output to the address generator 210. In order for the network administrator to select a type of network device and to input a device type code and a maximum allocated device number, the device information setting unit 200 displays an input window as shown in FIG. Sets the device type code and the maximum assigned device number as the Internet Protocol pool.

The address generator 210 receives the MAC address and the network device type of each of the network devices through the input terminal IN2, and then uses the device type code corresponding to the set result of the device information setting unit 200. Create an Internet Protocol address.

In order to be able to input the MAC address and network device type of each of the network devices, the address generator 210 displays an input window as shown in FIG. 4. The address generator 210 generates an Internet protocol address of each of the network devices by using a device type code corresponding to the network device type of each of the network devices input by the network administrator, and generates the MAC address matching unit 220. )

The address generator 210 may include numerical information within the maximum number of allocated devices set by the device information setting unit 200 when generating the respective Internet protocol addresses. For example, if the network device type is "TV", and the maximum allocation device number corresponding to the maximum number of Internet protocol addresses that can be allocated to "TV" is "100", the address generator 210 Numerical information included in the Internet protocol address should be specified as numerical information within "100". This indicates that the number of "TVs" that can be assigned as Internet protocol addresses is limited to within "100".

The MAC address matching unit 220 matches each MAC address of the network devices with each generated Internet protocol address. Upon receiving each of the Internet protocol addresses generated from the address generator 210, the MAC address matching unit 220 receives the MAC addresses of the respective network devices previously input to the address generator 210 and the respective Internet protocols. The addresses are matched and the matching result is output to the address allocator 230 at the request of the address allocator 230.

The address allocator 230 allocates a specific Internet protocol address corresponding to the MAC address of the specific network device according to the request for the assignment of the Internet protocol address to the specific network device. When the allocation request signal of the Internet protocol address for a specific network device is input through the input terminal IN3, the address allocator 230 detects the specific MAC address of the specific network device transmitted together with the allocation request signal of the Internet protocol address. . The address allocator 230 checks whether the detected specific MAC address is among the MAC addresses matched with the Internet protocol addresses by the MAC address matching unit 220. If there is a specific MAC address among the matched MAC addresses, the address allocator 230 allocates the specific Internet protocol address matched with the specific MAC address as the Internet protocol address of the specific network device.

The present invention has been described with reference to the embodiment shown in the drawings for the purpose of the Internet protocol address allocation method and apparatus for illustrative purposes only, this is merely exemplary, various modifications and equivalents from those skilled in the art It will be appreciated that other embodiments are possible. Therefore, the true technical protection scope of the present invention will be defined by the appended claims.
