Description

System for Providing the Internet Address Supplementary Services and Method

The present invention relates to a network technology using a unique address, such as the Internet, that is, a method for providing additional information of an Internet Protocol address (hereinafter referred to as an IP address or an Internet address) and a system therefor.

Internet address is composed of 32 bits, and it is written in 8 bit units separated by punctuation and '.' Like "168.126.72.72". Internet addresses are largely A (0.xxx to 127.xxx), B (128.0.xx to 191.255.xx), C (192.0.0.x to 223.255.255.x), and D (224.0.0.0 to 224.255.255.0 ) Are divided into four classes. Currently only classes A, B, and C are assigned to specific network users, and class D is used as an address for multicasting. There are 128 addresses in class A, 16,384 in class B, and 2,097,152 in class C. The Internet address is controlled by the Internet Assigned Numbers Authority (IANA) of the Internet, and the three non-profit regional Internet regions worldwide are the American Registry for Internet Numbers (ARIN), the Asia Pacific Network Information Center (APNIC), and the Reseaux IP Europeens (RIPE). Classes are assigned to organizations that require address assignment through the Regional Internet Registry (RIR).

In the current Internet architecture, there is no direct way to obtain other information except for the IP address, which is a unique address of the client system to which the Internet server system providing the service is connected.

1 is a block diagram of a conventional web service providing system. In the related art, the web client 20 connects to the web server 30 and delivers the client's IP address (for example, 168.126.72.72). Then, the web server 30 transmits the web page to the web client 20.

That is, in the related art, the web client 20 accesses the web server 30 using a Uniform Resource Locator (URL) address such as http://www.jingoc.co.kr, and the web server 30 connects to the web client 20. ) Is provided with a web page corresponding to the URL address used for the access. When the web client 20 accesses the web server 30, the IP address is transmitted to the web server 30.

As such, in the conventional Internet Protocol, the server system cannot obtain additional information other than the IP address of the client system to which the client system is connected. Therefore, in order to obtain additional information on the IP address, a separate additional process must be performed. do.

For example, when providing a web service, the web server can obtain limited information other than the IP address of the accessing web client only through an additional function through a domain name server (DNS).

2 is a block diagram of another conventional web service providing system. Conventionally, when the web client 20 accesses the web server 30 and delivers the client's IP address (①), the web server 30 searches for the WHOIS using the IP address of the web client through the INTERNIC WHOIS database 40. (②), the INTERNIC WHOIS database 40 transmits the DNS IP address of the IP according to the search to the web server 30 (③), and the web server 30 is the DNS system of the network to which the web client belongs. Request 50 to Inverse Lookup of IP address (④). Then, the DNS system 50 of the network belonging to the web client transmits kids.kotel.co.kr or www.hose.com as the full domain name of the IP to the web server 30 (⑤). The web server 30 transmits the reconfigured web page to the web client 20 again using the domain of IP (6).

As described above, the web server 30 may obtain domain information of the IP address by using an inverse lookup for the IP address of the web client 20. To this end, the web server 30 retrieves the IP address of the DNS system of the network including the IP address through the WHOIS database system 40 of INTERNIC, and if the search result is successful, the DNS address. The client accesses the DNS system 50 to which the client 20 belongs, and searches the domain name of the client 20 to which the client 20 is connected. The web server 30 may obtain additional information about the IP address of the client 20 connected by using the search result.

This conventional method has had problems in various aspects. First, for the inverse lookup service, information for the inverse lookup should be registered by the network manager to which the client 20 belongs in the case of Internic or the case of each country.

Second, even when the information for the inverse lookup is registered in the case of Internic or the case of each country, the access may not be allowed in the Internic whoo server 40 which limits the number of times of connection per unit time for each system. Therefore, if the Huis server 40 cannot be accessed or the inverse lookup information is not registered, domain information through the inverse lookup cannot be obtained, resulting in waste of system load and processing time for the inverse lookup. And even if the inverse lookup is successful, there is a service delay problem due to the system load and processing time for the inverse lookup in the web server with many connections.

Third, additional information that can be obtained by this method is very limited. Meaningful information available includes country-level TLD (cTLD: Country Top Level Domain) information about the country (eg kr = Korea) and the domain's attributes (eg com). have. In other words, in case of general TLD (gTLD: General TLD) such as ".COM", ".NET", and ".ORG", only the information on the domain attribute can be obtained. In order to identify the country of access to the gTLD, it is necessary to re-search the relevant information in the INTERNIC WHOIS database using the domain obtained through the DNS and infer the region through the registration information for the domain. Due to the time and system load, there is a lot of constraints on the practical use due to the inferior reliability problem.

Therefore, the IEC's Internet Engineering Task Force (IETF) proposes a new approach to providing local information about IP addresses and proposes a method that can add local information to DNS, but each network has its own DNS. The only limitation is that the software can be upgraded and configured to provide local information.

Alternatively, the web server can obtain additional information of the web client by using a cookie. However, the use of cookies should not be restricted in the web client accessing the web server, and information input required by the web server is required at the initial cookie setting. If the use of web client cookies is restricted, additional information cannot be obtained. Even if the web client cookie configuration is enabled, the previous cookie information is lost when resetting the cookie-related information. In this way, the use of cookies is restricted depending on the preferences and usage of the client.

In particular, until now, IP address supplementary information providing systems and methods have been provided for providing fast and accurate and efficient information using IP addresses as keywords for counterpart systems (clients) accessing server systems such as the web connected to the Internet. Did.

The present invention was devised to solve various problems as described above, and provides various information about a counterpart system (client) that accesses a server system such as a web connected to the Internet by using IP address as a keyword and quickly and efficiently. It is an object of the present invention to provide a system and method for providing IP address additional information.

Other objects and advantages of the present invention will become more apparent from the following detailed description of the invention and the accompanying drawings.

First, the processing on the client side will be described. In the state where the web service providing system is waiting for the service (s10), if there is a search request from the web server 30 (s100), the IP address additional information client 100 grasps the IP address and the service type (s20). Thereafter, the local cache 130 classifies the IP address and the service type (s30), and checks whether the search is successful (s40). If the search is successful, the search result is reported to the web server 30. If the search fails, it is determined whether the requested service is a local service (S50).

If the requested service is a local service, the local data is searched (s60). After retrieving the local data, it is determined whether the retrieval is successful (S70). If the retrieval of the local data is successful, the local cache 130 is updated (s80), and the search result is reported to the web server 30 (S100). If the retrieval of the local data fails, the local error log is stored (s90). The search results are reported to the web server 30.

As a result of the determination (s50), if the requested service is not a local service, a request is made to the IP address additional information providing server 200 in the standby state (s55).

Now, the processing on the server side is as follows. When the IP address additional information providing server 200 is in the standby state (s200) and receives a search request from the IP address additional information providing client 100, the IP address additional information providing server 200 and the web server 30 identify the IP address and service type. (s210). The server cache 210 for each site searches for an IP address (s220), and then determines whether the search is successful (s230).

The determination result (s230) If the search is successful, and analyzes the search results (s280) to determine whether the search is successful again (s290). If the check result (s290) is successful, the local cache 130 is updated (s80) and the search result is reported to the web server 30. However, if the search fails in step s290, the local error log is stored (s90) and the search results are reported to the web server 30 (s100).

On the other hand, if the search fails in step S230, the IP additional information database 220 is searched (s240) and it is determined whether the search is successful (s250). As a result of the determination (s250), if the search is successful, the server cache 210 for each site is updated (s260), and if it fails, the error log is stored (s270) and the search result is analyzed (s280). The subsequent process is as described above.

The present invention can be variously modified and can take various forms and only the specific embodiments thereof are described in the detailed description of the invention. It is to be understood, however, that the present invention is not limited to the specific forms mentioned in the detailed description of the invention, but rather includes all modifications, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
