JP5314666B2 - User terminal correspondence analysis system and method - Google Patents

Description

  The present invention relates to a user terminal correspondence analysis system and method.

  Conventionally, an ISP (Internet Service Provider) provides a connection service for connecting a user terminal to the Internet. In the ISP connection service, the URI (Uniform Resource Identifier) received from the user terminal is analyzed, and the host name of the Web server to be accessed is extracted. If an IP address (Internet Protocol address) is not associated with the host name of the retrieved Web server, the host name is passed to the ISP resolver server as an unresolved name. The ISP resolver server inquires of the DNS server (Domain Name System server) about the unresolved host name. The DNS server returns the IP address associated with the host name to the ISP resolver server and performs name resolution. The ISP connects the user terminal and the Web server using the IP address of the Web server resolved by name resolution.

  Here, the name resolution is an IP address (for example, 111) of a fully qualified domain name (FQDN) that is a host name (for example, www.jpo.go.jp) that is fully conditioned up to the top level domain (for example, jp). 122.133.144). Japanese Patent Application Laid-Open No. 2004-151867 is known that enables a client of a mobile network to be guided to an optimum edge server in consideration of the position of the client by using such name resolution.

  The system disclosed in Patent Document 1 stores a DNS server that is a destination of a client when the client moves from the home network to another area (external network), and accesses content from the destination client. When there is a request for name resolution, the client is guided to the edge server of the external network based on the IP address of the DNS server of the destination external network.

By the way, if a business provider that provides various services using a Web server can acquire the relationship between the resolver server that intervenes for name resolution in the ISP and the corresponding user terminal, it can provide services with various added values. It can be carried out.
For example, when a connection is established using IPv6 (Internet Protocol Version 6) only within an ISP network, a Web server that communicates with a user terminal via the Internet needs to communicate using IPv4 (Internet Protocol Version 4). . However, when name resolution is performed using IPv6 when a predetermined resolver server of the ISP requests the DNS server to perform name resolution using IPv6, it is not possible to communicate with a user terminal that can communicate only with an external server using IPv4. Therefore, if the relationship between the user terminal and the corresponding resolver server can be acquired, even when the predetermined resolver server of the ISP makes a name resolution request to the DNS server with the IPv6 IP address, the user terminal Name resolution can be performed with an IPv4 IP address with which can communicate.
Alternatively, it is known that information on a region where the user terminal is located can be obtained via a cookie or user ID of the user terminal. If the relationship between the user terminal and the corresponding resolver server can be acquired, the area covered by the resolver server can be estimated. As a result, content corresponding to the area can be provided from the Web server to another user terminal whose area is unknown, using the corresponding resolver server as a clue.

Since the beacon 101 is one of the pixels constituting the web page, the user hardly sees the beacon 101 itself. Then, a specific FQDN that cannot be resolved (that is, a new FQDN) is transmitted from the resolver server 30 to the DNS server 40.

  Next, FIG. 10 to FIG. 12 show an example of the correspondence information DB 611 created when there is a user terminal 10 that can communicate only with an external server by IPv4. FIG. 10 is a diagram illustrating an example of storing the IPv6 IP address of the IP address collection server 50 in another example of the DNS log DB 411 according to an embodiment of the present invention. FIG. 11 is a diagram illustrating an example in which the user terminal 10 that can communicate only with IPv4 is not stored in another example of the page request log DB 511 according to an embodiment of the present invention. FIG. 12 shows an example in which the user terminal 10 that is not associated with the IP address of the resolver server 30 is determined as the user terminal 10 that can communicate only with IPv4 in another example of the correspondence information DB 611 according to the embodiment of the present invention. FIG.

That is, as shown in FIG. 10, when the DNS server 40 receives the name resolution request for the specific FQDN from the resolver server 30, the IPv6 IP address of the IP address collection server 50 (for example, , 0: 0: 0: 1), and the specific FQDN is associated with the IP address of the resolver server 30 and stored in the DNS log DB 411. In FIG. 10, for the sake of explanation, it is described that the IPv6 IP address (for example, 0: 0: 0: 1) of the IP address collection server 50 is stored. Good.
Next, as shown in FIG. 11, the IP address collection server 50 receives the IPv6 IP address of the IP address collection server 50 from the resolver server 30, and the user terminal 10 can communicate with an external server via IPv6. Then, in response to a page request related to the specified FQDN for which the name has been resolved, the IP address of the user terminal 10 and the specified FQDN are associated with each other and stored in the page request log DB 511.
Next, as illustrated in FIG. 12, the aggregation server 60 determines the correspondence between the IP address of the resolver server 30 collected from the DNS log DB 411 and the IP address of the user terminal 10 collected from the page request log DB 511. Store in the information DB 611. As a result, the aggregation server 60 can detect the identifying FQDN that does not correspond to the IP address of the resolver server 30 with the IP address of the resolver server 30, and the user terminal 10 associated with the identifying FQDN can be detected using IPv4. It can be determined that the user terminal 10 can only communicate. Based on this information, for example, the resolver server 30 can extract the user terminal 10 that can communicate only with IPv4 by analyzing the log information stored in the resolver server 30, so that the user terminal 10 communicates. Name resolution can be performed with an IPv4 IP address that can be used.

  Next, with reference to FIGS. 13 and 14, the case where the aggregation server 60 associates the regional information with the resolver server 30 will be described.

FIG. 13 is a diagram illustrating an example of the user registration information DB 90. FIG. 14 is a diagram showing still another example of the correspondence information DB 611 according to an embodiment of the present invention.

The user registration information collection unit 604 collects user registration information that is information about the user associated with the user terminal 10. The user registration information is, for example, user information stored in a user registration information DB 90 stored by a user registration information server (not shown) and associated with user identification information as shown in FIG. Therefore, the user registration information collection unit 604 can acquire user registration information (for example, a hobby or an address) by inquiring with user identification information (for example, a user ID or an IP address of the user terminal 10). .
The resolver area association unit 605 associates the user's address in the user registration information collected by the user registration information collection unit 604 with the resolver server 30 associated with the IP address of the user terminal 10 of the user. The resolver area association unit 605 may obtain a corresponding area (for example, Tokyo to Kanto) further associated with the user's address. That is, the correspondence information DB 611 stores the IP address of the user terminal 10 and the corresponding area in association with the IP address of the resolver server 30 as shown in FIG.
The area covered by the resolver server 30 can be estimated based on the relationship between the user terminal 10 and the corresponding resolver server 30. Thereby, based on the corresponding resolver server 30, the content according to the said area can be provided with respect to the other user terminal 10 whose area is unknown.

According to the present embodiment, the user terminal correspondence analysis system 1 includes the Web server 20, the DNS server 40, the IP address collection server 50, and the aggregation server 60 connected by the communication network 70. The correspondence relationship between the resolver server 30 and the user terminal 10 is analyzed.
In response to receiving a predetermined page request from the user terminal 10, the Web server 20 assigns a specific FQDN including a unique host name that has not been resolved for each page request, and assigns the assigned specific FQDN It transmits to the user terminal 10.
The resolver server 30 receives the specific FQDN from the user terminal 10 and transmits the received name resolution request for the specific FQDN to the DNS server 40.
The DNS server 40 resolves the name by associating the IP address of the IP address collection server 50 with the specific FQDN in response to receiving the name resolution request for the specific FQDN from the resolver server 30, and the IP address of the resolver server 30. Is stored in the DNS log DB 411 in association with the specific FQDN, and the IP address of the IP address collection server 50 whose name is resolved is transmitted to the resolver server 30.
The resolver server 30 transmits the IP address of the IP address collection server 50 to the user terminal 10 in response to receiving the IP address of the IP address collection server 50 whose name has been resolved for the specific FQDN from the DNS server 40.
The IP address collection server 50 stores the IP address of the user terminal 10 and the specifying FQDN in the page request log DB 511 in response to a page request related to the specifying FQDN from the user terminal 10. .
The aggregation server 60 collects the IP address of the resolver server 30 associated with the specific FQDN from the DNS log DB 411 and collects the IP address of the user terminal 10 associated with the specific FQDN from the page request log DB 511. The correspondence relationship in which the collected IP address of the resolver server 30 and the collected IP address of the user terminal 10 are associated with the same FQDN for identification is stored in the correspondence relationship information DB 611. Therefore, the user terminal correspondence analysis system 1 can specify the correspondence between the user terminal 10 and the resolver server 30. Further, in response to receiving a predetermined page request from the user terminal 10, the Web server 20 associates the specifying FQDN with information indicating the location of the beacon, and transmits the beacon to the user terminal 10. Therefore, the user terminal correspondence analysis system 1 can identify the correspondence between the user terminal 10 and the resolver server 30 without making the user aware of it.
