Abstract

PURPOSE: An intelligent name server is provided to inform an IP address of a server capable of responding to a request of a client rapidly in case that a plurality of servers for supplying an Internet service using one domain is existed. CONSTITUTION: A client(100) means a program for receiving information using an Internet network as a web browser, an FTP(File Transfer Protocol) client, and a Usenet client which uses an NNTP(Network News Transfer Protocol). Servers(160,170,180,190) for supplying an Internet service in accordance with a representative domain on the Internet are existed through the whole world by making an area and an ISP(Internet service providers) company be different, and the client(100) queries to an I-name server(110) an information of an IP address of a server which is supplies an Internet service to a representative domain address of the client(100). The I-name server(110) checks the IP address of the client(100) and searches an ISP company for receiving the corresponding IP address from an InterNIC(internet network information center), and checks a country and an area of the corresponding ISP company, and checks a path be routed to a trace route, and searches the local area of the corresponding IP and a connection state of the corresponding IP in an ISP company. Thus, the I-name server(110) searches an IP address, a local area, and ISP company information of the servers(160,170,180,190) for supplying Internet services in the representative domain in a database, and informs an IP address of a server capable of supplying an Internet service to the client rapidly(100).

Description

Intelligent Name Server {i-nameserver}

The present invention relates to a processing method for providing an IP address for a domain on the Internet. In particular, the present invention provides an IP address of a server capable of providing the fastest network access speed with the client according to the local location of the client and the ISP company in use. It relates to a treatment method.

Conventional name server technology simply enters multiple IP addresses in one domain, and informs the client of one of the IP addresses in a round-robin fashion when the client requests it. As the Internet is able to provide services all over the world over time and space, it is common to have multiple servers for Internet services provided by one domain. The current round-robin technology is applicable in Korea. Even if there is a server capable of providing a service in Korea to a client requesting an Internet service, the server can provide the IP address of a server in the United States. This occurs as a factor that slows down the overall Internet.

In order to solve this problem, the current Internet technology has multiple mirroring sites for each local and ISP company, and the mirroring site that client users can achieve the fastest network connection speed compared to their local and ISP companies. However, the client user can determine the address of the most suitable mirroring site based on the local location, the network connection speed between the ISP company in use and the ISP company in which the mirroring site is operated, and then re-enter the address. There is the inconvenience of having to connect.

Therefore, in view of the above problems, the present invention provides a client with a representative domain when multiple servers providing Internet services provided by one representative domain are operated at a local or multiple ISP company or at a data center connected to the ISP company. When inquiring about the IP address for the name server, the client's IP address is analyzed, the client's ISP company and the local location are identified, and based on this, the inquiry is made from the database of the system proposed by the present invention to the client at the fastest speed. The service can be provided and the client will be informed of the IP address of the server that is providing the service. This eliminates the need for Internet service providers to operate multiple mirroring sites and to inform the client's users of their mirroring site addresses. It is convenient that one of the representative domains automatically accesses among the mirroring sites without knowledge of speed.

In addition, since the Internet service provider can know the local country where the client is located based on the IP address of the client, in providing the Internet service, the IP address of the server that preferentially provides the first public language of the country to which the client is connected is provided. You will be notified.

In the processing method of finding an IP address of a server close to a client using the i-name server of the present invention having the above object, a name server query process in which a client queries a name server for a representative domain address: the IP address of the client in the name server Identifying the client's Internet access point and ISP company using the client Verification process: The process of finding the IP address closest to the client among the IP addresses of the server registered in the name server with the representative domain: The process of checking whether the internet service can be provided properly for the IP addresses of the registered servers for all the representative domains in a time period and updating the information in the DB of the i-name server system: and finally, the i-name server The system responds to the request of an IP address according to the representative domain of the initial client. This is done by telling the client the appropriate IP address.

On the other hand, if the service is not provided to the IP address requested by the client, the process includes the step of performing the process again. The adaptive server IP address rounding process according to the local location of the client using the present invention i-name server system will be described in detail with reference to the accompanying drawings.

The client 100 refers to a program that receives information using an internet network such as a web browser, an FTP client, and a USENET client using the NNTP protocol. Servers that provide Internet services according to the representative domains on the Internet (160, 170, 180, 190) exist throughout the world in different regions and ISP companies. The client does not know the IP address of each server and only wants to find the IP address with the representative domain. . To this end, the client 100 queries the i-name server 110 to inform the IP address of the server providing the Internet service to the representative domain as the representative domain address known to the i-name server 110. At this time, the i-name server 110 checks the client's IP address, finds the ISP company assigned the IP address in InterNIC, checks the country and region of the ISP company, and checks the route routed to traceroute. Check the local location of the IP and find out the connection status of the IP within the ISP. Based on this, i-name server finds IP address, local location, ISP company information of servers (160, 170, 180, 190) that provide Internet service in representative domain requested by client, The client is informed of the IP address of the server 160 that can receive the service.

Then, the client requests the Internet connection from the server 160 based on the IP address 160 found in the i-name server, and receives the Internet service.

As described above, the IP address notification according to the representative domain using the 'intelligent name server system' of the present invention informs the client of the address of the server that can effectively provide the service according to the local location of the client as one representative domain. According to the location, it is possible to provide various other additional services.
