Description

Technical Field

[0001] The present invention relates to the field of network communications, specifically to the field of IP identification, and more specifically to a method for identifying and locating a home bandwidth IP and a system for identifying and locating a home bandwidth IP. Background Art

[0002] With the rapid development of internet services, businesses are increasingly demanding the geographic location (also referred to in this application as usage location) of source IP addresses (also known as target IP addresses). Generally speaking, these IP location needs fall into two main categories: 1) analyzing users in different regions to achieve targeted marketing; and 2) analyzing anomalous user behavior to address marketing fraud, such as scraping, spamming, and order manipulation. As the primary IP type in China (nearly 5 billion IP addresses are allocated to home broadband), accurate identification and location of these IP addresses are crucial for both marketing and anomaly analysis.

[0003] Existing IP location locating technologies can be categorized into two types: 1) This involves collecting information about domestically allocated IP addresses (including assigned IP addresses and registered ownership information) through WHOIS and BGP. Probe nodes (e.g., probe machines) are then deployed in various regions to enumerate domestically allocated IP addresses one by one, using commands like ping and traceroute to determine latency and network paths. This ultimately leads to the calculation of the likely geographic location of the allocated IP address. 2) This involves collecting user IP and GPS information through mobile terminals, and then analyzing the distribution of GPS information corresponding to the IP address to determine the IP address's geographic location. While the former method can estimate the location of allocated IP addresses, allocated IP addresses only respond to ICMP commands when they are actively dialing. Most allocated IP addresses are unallocated and therefore cannot be detected by ping or traceroute. Therefore, using the likely geographic location of an allocated IP address to estimate the source IP address carries the risk of miscalculation. Furthermore, locating allocated IP addresses using mobile device information requires a client-side SDK to collect information, which requires a large number of existing terminal users.

[0004] In summary, the prior art of identifying and locating the access source IP based on estimated possible location information has the risk of inaccurate identification and positioning. Summary of the Invention

[0005] Therefore, the purpose of the present invention is to overcome the above-mentioned defects of the prior art and provide a method for identifying and locating a home bandwidth IP and a system for identifying and locating a home bandwidth IP.

[0006] The present invention is achieved through the following solutions:

[0007] According to a first aspect of the present invention, a method for identifying and locating a home bandwidth IP is provided for identifying and locating a target IP to be analyzed, the method comprising: S1, obtaining path exploration feedback information, IP type feedback information, and registered ownership information of an allocated IP, and obtaining in real time the reference home bandwidth IP uploaded by a dial-up server and usage location information corresponding to the reference home bandwidth IP; S2, using the IP type feedback information of the allocated IP obtained in step S1 as a reference, marking the allocated IP with a target home bandwidth IP to obtain a target home bandwidth IP and a non-target home bandwidth IP, and adding usage location information to the target home bandwidth IP according to a first preset rule based on the path exploration feedback information corresponding to each target home bandwidth IP; and The registered ownership information and usage location information of the household bandwidth IP constitute the target household bandwidth IP initial information; S3, based on the initial information of all target household bandwidth IPs obtained in step S2, the target household bandwidth IPs with the same registered ownership information and belonging to the same allocated IP segment are expanded with usage location information according to the second preset rule to obtain the target household bandwidth IP information. Each target household bandwidth IP belonging to the same allocated IP segment in the target household bandwidth IP information corresponds to the same usage location information; S4, taking the IP as the benchmark, using the benchmark household bandwidth IP and the usage location information corresponding to the benchmark household bandwidth IP obtained in real time to calibrate the target household bandwidth IP information to obtain the calibrated target household bandwidth IP information; S5, using the calibrated target household bandwidth IP information to identify and locate the target IP to be analyzed.

[0008] In some embodiments of the present invention, the IP type feedback information of the allocated IP includes home broadband port response information. In step S2, the allocated IP whose home broadband port response information is that there is a port response is marked as the target home bandwidth IP, and the allocated IP whose home broadband port response information is that there is no port response is marked as a non-target home bandwidth IP.

[0009] In some embodiments of the present invention, the path exploration feedback information of the allocated IP also includes detection delays of multiple priorities between the allocated IP and the detector, and the first preset rule includes: comparing the detection delays of multiple priorities corresponding to the target home bandwidth IP with the delay threshold respectively; when it is determined that the detection delay of each priority corresponding to the target home bandwidth IP is less than the delay threshold, the pre-arranged location information of the detector is used as the usage location of the target home bandwidth IP; when it is determined that the detection delay of each priority corresponding to the target home bandwidth IP is not less than the delay threshold, the usage location of the target home bandwidth IP is set to empty.

[0010] In some embodiments of the present invention, the allocated IP segment is segment C, and the second preset rule is: count the number of IPs with the same registered ownership information and the same usage location information belonging to the target home bandwidth IP in an allocated IP segment; use the usage location information corresponding to the largest number of all IP addresses as the usage location information of each target home bandwidth IP with the same registered ownership information and belonging to segment C.

[0011] In some embodiments of the present invention, in step S4, calibration is performed through the following steps: each target home bandwidth IP and each non-target home bandwidth IP in the target home bandwidth IP information are compared for consistency with the obtained benchmark home bandwidth IP; when the comparison results of the non-target home bandwidth IP and the benchmark home bandwidth IP are consistent, the usage location information and IP type of the non-target home bandwidth IP are correspondingly covered with the IP type and the corresponding usage location information in the corresponding benchmark home bandwidth IP; when the comparison results of the target home bandwidth IP and the benchmark home bandwidth IP are consistent, the usage location information of the target home bandwidth IP is correspondingly covered with the usage location information of the corresponding benchmark home bandwidth IP.

[0012] In some embodiments of the present invention, the calibrated target home bandwidth IP information includes the usage location information and IP type of the covered non-target home bandwidth IP, the usage location information of the uncovered target home bandwidth IP, and the usage location information of the covered target home bandwidth IP.

[0013] In some embodiments of the present invention, step S5 includes: comparing the target IP to be analyzed with each target home bandwidth IP in the calibrated target home bandwidth IP information for consistency; using the usage location information of the target home bandwidth IP consistent with the target IP to be analyzed as the usage location of the target IP to be analyzed, and identifying the target IP to be analyzed as a home bandwidth IP.

[0014] According to a second aspect of the present invention, a system for identifying and locating a home bandwidth IP is provided, for identifying and locating a target IP to be analyzed. The system includes a dial-up server, a plurality of pre-deployed probes, and a server.

[0015] The dial-up server is configured to: obtain the benchmark home bandwidth IP and the usage location information corresponding to the benchmark home bandwidth IP by dialing according to a preset time period, and upload them to the server; each detector is configured to obtain the ownership information of the allocated IP and the allocated IP registration, and perform path exploration and IP type exploration on the obtained allocated IP to obtain the path exploration feedback information and IP type feedback information of the allocated IP; upload the obtained ownership information of the allocated IP and the allocated IP registration, path exploration feedback information, and IP type feedback information to the server; the server is configured to: identify and locate the target IP to be analyzed using the method provided in the first aspect of the present invention.

[0016] Compared with the existing technology, the advantages of the present invention are: the initial information of all target home bandwidth IPs with the same registered ownership information and belonging to the same allocated IP segment are expanded with usage location information to obtain the target home bandwidth IP information; the target home bandwidth IP information is calibrated using the benchmark home bandwidth IP and the usage location information corresponding to the benchmark home bandwidth IP obtained in real time, and then the target IP to be analyzed is identified and located based on the calibrated target home bandwidth IP information, which can greatly improve the accuracy and coverage of the identification of the home bandwidth IP.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below through specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] As mentioned in the background art, in the prior art, there is a risk of inaccurate identification and positioning when identifying and positioning the access source IP based on estimated possible location information.

[0022] In order to solve the above problems, the inventors of the present application conducted further analysis on the above problems.

[0023] The prior art enumerates domestically assigned IP addresses one by one, calling commands like ping and traceroute to obtain latency and network paths, ultimately calculating the probable geographic location of the assigned IP. Using this probable geographic location for identifying and locating the target IP to be analyzed can lead to significant discrepancies. This is primarily due to the irrationality of the calculation method used to calculate the probable geographic location of the assigned IP, and the lack of a mechanism to calibrate the probable geographic location of the assigned IP. This results in significant discrepancies in the identification and location of the target IP to be analyzed. Therefore, embodiments of the present invention logically improve the calculation method for the probable geographic location of the assigned IP to obtain more accurate basic IP information. This information is then calibrated using the reliability of dial-up network data, resulting in a more accurate benchmark for identifying and locating the target IP to be analyzed. This improves the accuracy of identifying and locating the target IP to be analyzed. A more accurate benchmark also allows for greater coverage of the identification and location of the target IP to be analyzed. It should be noted that since home bandwidth IPs account for a high proportion of assigned IP addresses, the following explanation uses home bandwidth IPs as an example.

[0024] According to one embodiment of the present invention, a method for identifying and locating a home bandwidth IP is provided for identifying and locating a target IP to be analyzed, the method comprising: S1, obtaining path exploration feedback information, IP type feedback information, and registered ownership information of an allocated IP, and obtaining in real time the reference home bandwidth IP uploaded by a dial-up server and usage location information corresponding to the reference home bandwidth IP; S2, using the IP type feedback information of the allocated IP obtained in step S1 as a reference, marking the allocated IP with a target home bandwidth IP to obtain a target home bandwidth IP and a non-target home bandwidth IP, and adding usage location information to the target home bandwidth IP according to a first preset rule based on the path exploration feedback information corresponding to each target home bandwidth IP; and The registered ownership information and usage location information of the home bandwidth IP constitute the target home bandwidth IP initial information; S3, based on the initial information of all target home bandwidth IPs obtained in step S2, the target home bandwidth IPs with the same registered ownership information and belonging to an allocated IP segment are expanded with usage location information according to a second preset rule to obtain the target home bandwidth IP information. Each target home bandwidth IP belonging to an allocated IP segment in the target home bandwidth IP information corresponds to the same usage location information; S4, based on the IP, the target home bandwidth IP information is calibrated using the benchmark home bandwidth IP and the usage location information corresponding to the benchmark home bandwidth IP obtained in real time to obtain the calibrated target home bandwidth IP information; S5, the target IP to be analyzed is identified and located using the calibrated target home bandwidth IP information.

[0025] In order to better understand the embodiments of the present invention, step S1 , step S2 , step S3 , step S4 , and step S5 are explained in detail below with reference to the accompanying drawings.

[0026] In step S1, Figure 1As shown, allocated IP addresses can be directly obtained on demand by parsing Whois and BGP data. The protocols used include IP WHOIS and routing protocols. WHOIS (Who Is) is a protocol used to query domain name registration information, while IP WHOIS is a derivative protocol for querying IP addresses. IP WHOIS allows users to query detailed information such as the owner or registration information (registered ownership information), contact person, and geographic location of an IP address (sometimes referred to herein as "IP"). IP WHOIS queries are typically maintained by the Internet Assigned Numbers Authority (IANA) and various Regional Internet Registries (RIRs). This information is publicly available and can be obtained through the WHOIS query tool or the websites of the various Regional Internet Registries (RIRs). BGP is the preferred routing protocol. BGP is the only routing protocol that uses TCP as the transport layer and is primarily used to exchange network reachability information between two AS domains. Network reachability information refers to the AS number path to a specified IP prefix. Therefore, BGP data can be used to collect and organize information about IP segments broadcast by autonomous systems (ASs) around the world, as well as information about the organizations to which these ASs belong. ris.ripe.net is a public BGP routing information service provided by the RIPE NCC (Réseaux IP Européens Network Coordination Centre), which allows users to query and download global BGP routing information. RIPE NCC is the European Internet Assigned Numbers Authority (RIR), responsible for the allocation and registration of IP addresses and Autonomous System Numbers (ASNs) in Europe, the Middle East, and parts of Asia. To better illustrate Whois and BGP data, the following provides examples of Whois and BGP data.

[0027] Among them, the IP WHOIS data (Whois data) is: IP address range: 202.120.0.0-202.120.255.255; Ownership: Computer Network Information Center, Chinese Academy of Sciences; Contact: Mr. Wang; Contact email: wang@nic.ac.cn; Contact number: +86-10-58812469; Geographic location: Haidian District, Beijing, China; Registration information: APNIC; Network service provider: Computer Network Information Center, Chinese Academy of Sciences; AS number: AS4538.

[0028] Some information about the allocation organization can be obtained through router information (BGP data): AS router: AS4808iBasis HK Ltd; network IP address: 202.68.64.0 / 19; next-hop router: 202.68.64.1; AS path: 48084637 3491 9808 4637; reachability: reachable.

[0029] In step S1, the path exploration feedback information and IP type feedback information of the allocated IP can be obtained by using a pre-arranged detection machine ping, traceroute, or telnet to detect the allocated IP. The acquisition method here is a technology well known to those skilled in the art and will not be described in detail here.

[0030] In step S1, Figure 1 As shown, collecting home bandwidth IP information involves obtaining real-time home bandwidth IP information uploaded by the dial-up server. This information includes the baseline home bandwidth IP and the corresponding usage location information. The baseline home bandwidth IP includes the allocated IP and the corresponding home bandwidth IP type. It should be noted that the dial-up server is deployed in the Second Dial network. Second Dial leverages the principle that most home broadband networks dynamically allocate IP addresses, creating a dial-up VPS network that can switch IP addresses at any time. The process of obtaining home bandwidth IP information using the Second Dial network is well known in the art and will not be elaborated here.

[0031] According to one embodiment of the present invention, the IP type feedback information of the allocated IP includes home broadband port response information. In step S2, the allocated IP whose home broadband port response information is that there is a port response is marked as the target home bandwidth IP, and the allocated IP whose home broadband port response information is that there is no port response is marked as a non-target home bandwidth IP.

[0032] In step S2, according to one embodiment of the present invention, the path exploration feedback information of the allocated IP also includes detection delays of multiple priorities between the allocated IP and the detector, and the first preset rule includes: comparing the detection delays of multiple priorities corresponding to the target home bandwidth IP with the delay threshold respectively; when it is determined that the detection delay of each priority corresponding to the target home bandwidth IP is less than the delay threshold, the pre-arranged location information of the detector is used as the usage location of the target home bandwidth IP; when it is determined that the detection delay of each priority corresponding to the target home bandwidth IP is not less than the delay threshold, the usage location of the target home bandwidth IP is set to empty. It should be noted that the multiple priority levels of detection delay include: the probe machine uses ping to send a probe packet to the assigned IP address every 10 seconds, obtaining a first detection delay; and uses traceroute to detect the path of the assigned IP address every 10 seconds, obtaining a second detection delay; the first detection delay has a higher priority than the second detection delay; when both the first and second detection delays are less than 2 seconds, the probe machine's pre-set location information, such as a city, is used as the usage location information for the assigned IP address. If the assigned IP address is the target home bandwidth IP address, the usage location information is used as the target home bandwidth IP address. When both the first and second detection delays are not less than 2 seconds, the usage location is set to blank. Whether the usage location is set to blank or a specific location is set can be further confirmed during subsequent expansion or calibration operations. Furthermore, the target home bandwidth IP initial information is composed of the registered ownership information and usage location information of each assigned IP address and the target home bandwidth IP address after the target home bandwidth IP address is marked. In other words, the target home bandwidth IP initial information includes all information about the assigned IP address after the usage location and IP type are marked.

[0033] In step S3, according to one embodiment of the present invention, the allocated IP segment is Segment C. The second preset rule is: count the number of IP addresses with identical registered ownership information and belonging to the same target home bandwidth IP within the allocated IP segment and having the same usage location information; and use the usage location information corresponding to the largest number of all IP addresses as the usage location information for each target home bandwidth IP with identical registered ownership information and belonging to Segment C. For example, if the allocated IP is 223.208.209.1, the smallest field represented by the allocated IP segment of 1 is Segment C. The IP address segment owned by the Computer Network Information Center of the Chinese Academy of Sciences is 202.120.0.0 - 202.120.255.255, all of which are target home bandwidth IPs. When the usage location information of 202.120.255.0 -202.120.255.112 is city A, and the usage location information of 202.120.255.113 - 202.120.255.255 is city B, and city B has the largest number of corresponding IP addresses, city B will be used as the usage location information of each IP address in 202.120.255.0 -202.120.255.255.

[0034] In some embodiments of the present invention, in step S4, calibration is performed through the following steps: each target home bandwidth IP and each non-target home bandwidth IP in the target home bandwidth IP information are compared for consistency with the obtained benchmark home bandwidth IP; when the comparison results of the non-target home bandwidth IP and the benchmark home bandwidth IP are consistent, the usage location information and IP type of the non-target home bandwidth IP are correspondingly covered with the IP type and the corresponding usage location information in the corresponding benchmark home bandwidth IP; when the comparison results of the target home bandwidth IP and the benchmark home bandwidth IP are consistent, the usage location information of the target home bandwidth IP is correspondingly covered with the usage location information of the corresponding benchmark home bandwidth IP.

[0035] According to one embodiment of the present invention, the calibrated target home bandwidth IP information includes the usage location information and IP type of the non-target home bandwidth IP after coverage, the usage location information of the uncovered target home bandwidth IP, and the usage location information of the covered target home bandwidth IP. The calibrated target home bandwidth IP information is also as follows Figure 1 High-precision home broadband IP library.

[0036] The following are specific examples of extensions and overrides:

[0037] Through detection and analysis, we found that the following 97 target home bandwidth IPs are from Daqing City, Heilongjiang Province: 221.208.209.1 221.208.209.2 221.208.209.16 221.208.209.17 ....221.208.209.254

[0039] First, expand the collected target home bandwidth IP to segment C 221.208.209.0 / 24, and get

[0040] {"IP_CIDR": "221.208.209.0 / 24", "province": "Heilongjiang Province", "city": "Daqing City" ...}

[0041] Then the benchmark home bandwidth IP corresponds to the usage location information and IP type, for example:

[0042] {"ip": "221.208.209.4","province": "Heilongjiang Province", "city": "Suihua City".....}

[0043] {"ip": "221.208.209.5","province": "Heilongjiang Province", "city": "Suihua City".....}

[0044] {"ip": "221.208.209.6","province": "Heilongjiang Province", "city": "Suihua City".....}

[0045] {"ip": "221.208.209.7","province": "Heilongjiang Province", "city": "Suihua City".....}

[0046] The resulting high-precision home broadband IP library includes:

[0047] {"IP_CIDR": "221.208.209.0 / 30", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0048] {"IP_CIDR": "221.208.209.4 / 30", "province": "Heilongjiang Province", "city": "Suihua City" ...},

[0049] {"IP_CIDR": "221.208.209.8 / 29", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0050] {"IP_CIDR": "221.208.209.16 / 28", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0051] {"IP_CIDR": "221.208.209.32 / 27", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0052] {"IP_CIDR": "221.208.209.64 / 26", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0053] {"IP_CIDR": "221.208.209.128 / 25", "province": "Heilongjiang Province", "city": "Daqing City" ...},

[0054] It should be noted that when covering the corresponding information of non-target home bandwidth IP, it is necessary to add the IP type of the allocated IP and mark it as the target home bandwidth IP. This will not be illustrated here.

[0055] According to one embodiment of the present invention, step S5 includes: comparing the target IP to be analyzed with each target home bandwidth IP in the calibrated target home bandwidth IP information for consistency; using the usage location information of the target home bandwidth IP consistent with the target IP to be analyzed as the usage location of the target IP to be analyzed, and identifying the target IP to be analyzed as a home bandwidth IP.

[0056] Based on the above explanation, according to the second aspect of the present invention, a system for identifying and locating a home bandwidth IP is provided for identifying and locating a target IP to be analyzed. Figure 2 As shown, the system includes: a dial-up server (preferably arranged on a second-dial client), a plurality of pre-deployed probes (probe clients) and a server (service end).

[0057] The dial-up server is configured to: obtain the benchmark home bandwidth IP and the usage location information corresponding to the benchmark home bandwidth IP by dialing according to a preset time period, and upload them to the server; each detector is configured to obtain the ownership information of the allocated IP and the allocated IP registration, and perform path exploration and IP type exploration on the obtained allocated IP to obtain the path exploration feedback information and IP type feedback information of the allocated IP; upload the obtained ownership information of the allocated IP and the allocated IP registration, path exploration feedback information, and IP type feedback information to the server; the server is configured to: identify and locate the target IP to be analyzed using the method provided in the first aspect of the present invention.

[0058] Based on the highly accurate home bandwidth IP library obtained by the above solution, since IP location and classification are the main dependent features for marketing promotion and anomaly analysis as mentioned above, the enhanced accuracy here is of great help to the business growth of the enterprise.

[0059] It should be noted that although the above describes the various steps in a specific order, it does not mean that the steps must be performed in the above specific order. In fact, some of these steps can be executed concurrently or even in a different order as long as the required functions can be achieved.
