[0058] Figure 1 FIG. 1 is a flow chart of a method for determining a recursive resolution service scope in one embodiment of the present disclosure. Figure 1 As shown, the method for determining the recursive resolution service scope includes the following steps:

[0059] S1: extracting multiple domain name recursive resolution information from the resolution log of the secondary domain name resolution server in the domain name resolution system.

[0060] A secondary domain name resolution server and multiple clients are deployed in the domain name resolution system. The multiple terminals where the multiple clients are located can be distributed in multiple different regions. The secondary domain name resolution server is a server independent of each recursive resolution server of the domain name resolution system. The secondary domain name resolution server is used to record all domain name recursive query requests and corresponding domain name resolution results through resolution logs when the domain name resolution system processes domain name recursive query requests, and store each domain name recursive query request and corresponding domain name resolution result as a domain name recursive resolution information.

[0061] A plurality of domain name recursive resolution information is extracted from the resolution log of the secondary domain name resolution server. For example, all domain name recursive resolution information within a preset time period can be extracted from the resolution log.

[0062] S2: Determine multiple client addresses and multiple network protocol addresses of recursive resolution servers corresponding to multiple domain name recursive resolution information.

[0063] For each of the multiple recursive domain name resolution information, extract the client address that sends the recursive domain name resolution request, and extract the network protocol address of the recursive resolution server that processes the recursive domain name resolution request, thereby obtaining multiple client addresses and network protocol addresses of multiple recursive resolution servers corresponding to the multiple recursive domain name resolution information. The client address may include the Internet Protocol (IP) address of the client. The network protocol address of the recursive resolution server may include an IP address used to determine the actual location of the recursive resolution server, such as the egress IP address of the recursive resolution server.

[0064] S3: Determine actual addresses of the multiple recursive resolution servers based on the network protocol addresses of the multiple recursive resolution servers.

[0065] For each network protocol address of a plurality of recursive resolution servers, the actual address of each recursive resolution server can be determined by IP address positioning.

[0066] S4: Determine the service ranges of the multiple recursive resolution servers based on the actual addresses of the multiple recursive resolution servers and the domain name recursive resolution correspondence between the multiple client addresses and the network protocol addresses of the multiple recursive resolution servers.

[0067] Based on the domain name recursive resolution correspondence between multiple client addresses and the network protocol addresses of multiple recursive resolution servers, the multiple client addresses of the domain name recursive resolution service processed by each recursive resolution server in the multiple recursive resolution servers can be determined. Combined with the multiple actual addresses corresponding to the multiple client addresses, the actual addresses of all clients when each recursive resolution server provides the domain name recursive resolution service can be obtained, and then the service scope of each recursive resolution server can be determined.

[0068] In this embodiment, since the secondary domain name resolution server in the domain name resolution system can obtain all domain name recursive query requests and corresponding domain name query results processed by the domain name resolution system, and store them in the resolution log of the secondary domain name resolution server, multiple domain name recursive resolution information can be extracted from the resolution log of the secondary domain name resolution server, and then the actual addresses of the multiple recursive resolution servers and the domain name recursive resolution correspondence between the multiple client addresses and the network protocol addresses of the multiple recursive resolution servers can be determined based on the multiple domain name recursive resolution information, so that the service scope of the multiple recursive resolution servers in the domain name resolution system can be quickly and accurately obtained.

[0069] In some embodiments of the present disclosure, step S3 may specifically include: determining the actual address of each recursive resolution server based on at least one of the export network protocol address, identification code and name information of each recursive resolution server among the multiple recursive resolution servers, wherein the actual addresses of the multiple recursive resolution servers include the actual address of each recursive resolution server.

[0070] For each of the multiple recursive resolution servers, the exit IP address of the recursive resolution server and the identification code obtained after completing the registration with the address registration agency, that is, the name information of the recursive resolution server, can be obtained.

[0071] Among them, the exit IP address of the recursive resolution server refers to the IP address used when connecting from the local network of the recursive resolution server to the public Internet. The exit IP address is allocated by the service provider of the public Internet, and the actual address of the recursive resolution server corresponding to the exit IP address can be extracted from the registration information by the service provider of the public Internet.

[0072] For the identification code obtained after completing registration with the address registration agency, the registration address of the recursive resolution server corresponding to the identification code can be queried from the registration information of the recursive resolution server through the address registration agency as the actual address of the recursive resolution server.

[0073] For the name information of the recursive resolution server, the actual address of the corresponding recursive resolution server can be queried through the network. For example, the actual address of the recursive resolution server corresponding to the name information of the recursive resolution server can be queried through the correspondence between the name information and the actual address of the recursive resolution server published on the network.

[0074] In this embodiment, since the actual address of the recursive resolution server can be located through the export network protocol address, identification code and name information of the recursive resolution server, the actual address of each recursive resolution server can be quickly and accurately obtained based on at least one of the export network protocol address, identification code and name information of each recursive resolution server.

[0075] Figure 2 FIG. 4 is a flow chart of step S4 in some embodiments of the present disclosure. Figure 2 As shown, in some embodiments of the present disclosure, the multiple client addresses include network protocol addresses of multiple clients, such as the IP address of each of the multiple clients. Correspondingly, step S4 may include the following steps:

[0076] S4-1: Determine actual addresses of the multiple clients based on the network protocol addresses of the multiple clients.

[0077] For each of the network protocol addresses of the multiple clients, the actual address of each client can be determined by address positioning. For example, for each client's IP address, the actual address of each client can be queried through the IP address.

[0078] S4-2: Based on the domain name recursive resolution correspondence between the multiple client addresses and the network protocol addresses of the multiple recursive resolution servers, determine the domain name recursive resolution service relationship between the actual addresses of the multiple clients and the actual addresses of the multiple recursive resolution servers.

[0079] From the domain name recursive resolution correspondence between multiple client addresses and multiple network protocol addresses of recursive resolution servers, the client address in each domain name recursive resolution information and the network protocol address of the corresponding recursive resolution server are extracted.

[0080] By counting all the client addresses corresponding to each recursive resolution server in the above multiple domain name recursive resolution information, the actual addresses of all clients are obtained by locating the client addresses, and the corresponding relationship between each client address (such as IP address or physical address) and the actual address of the client is combined to obtain the domain name recursive resolution service relationship between the actual addresses of multiple clients and the actual addresses of multiple recursive resolution servers.

[0081] S4-3: Determine the service ranges of the multiple recursive resolution servers based on the domain name recursive resolution service relationship between the actual addresses of the multiple clients and the actual addresses of the multiple recursive resolution servers.

[0082] According to the actual address of each recursive resolution server and the actual addresses of all clients corresponding to each recursive resolution server obtained from the domain name recursive resolution service relationship between the actual addresses of multiple clients and the actual addresses of multiple recursive resolution servers, the service scope of each recursive resolution server, that is, the service scope of the above-mentioned multiple recursive resolution servers, can be determined.

[0083] In this embodiment, since the actual address of the client can be located through the network protocol address of the client, the domain name recursive resolution correspondence between multiple client addresses and the network protocol addresses of multiple recursive resolution servers, combined with the correspondence between the network protocol address of the client and the actual address of the client, can be counted to obtain the actual addresses of all clients corresponding to each recursive resolution server, thereby accurately determining the service scope of each recursive resolution server.

[0084] In some embodiments of the present disclosure, before step S1, the following steps may also be included:

[0085] S0: multiple clients on multiple terminals send multiple domain name recursive resolution requests to a domain name resolution system, and the domain name resolution system performs domain name resolution on the multiple domain name recursive resolution requests to obtain multiple domain name recursive resolution information. The multiple terminals are distributed in multiple regions.

[0086] Multiple clients on multiple terminals distributed in multiple different regions are used to send multiple domain name recursive resolution requests to the domain name resolution system, wherein each domain name recursive resolution request may include the client address, the address information of the target recursive resolution server, and the target address for domain name resolution.

[0087] After the domain name resolution system receives multiple domain name recursive resolution requests, the target domain name recursive resolution server corresponding to each domain name recursive resolution request performs domain name resolution on the target address, feeds back the domain name resolution result to the corresponding client, and sends the client address and address information of the target domain name recursive resolution server corresponding to each domain name recursive resolution request to the secondary domain name resolution server. The resolution log of the secondary domain name resolution server stores the client address and address information of the target domain name recursive resolution server corresponding to each domain name recursive resolution request, so as to determine the service scope of each recursive resolution server.

[0088] Figure 3 FIG. 1 is a schematic diagram of determining the service scope of a recursive resolution server in an example of the present disclosure. Figure 3As shown, the secondary recursive resolution server SN extracts 10 domain name recursive resolution information from the resolution log, including:

[0089] 1. The client C1 sends a first domain name recursive resolution request to the recursive resolution server N1, and the recursive resolution server N1 feeds back the domain name resolution result corresponding to the first domain name recursive resolution request to the client C1;

[0090] 2. The client C2 sends a second domain name recursive resolution request to the recursive resolution server N1, and the recursive resolution server N1 feeds back the domain name resolution result corresponding to the second domain name recursive resolution request to the client C2;

[0091] 3. The client C3 sends a recursive resolution request for a third domain name to the recursive resolution server N1, and the recursive resolution server N1 feeds back a domain name resolution result corresponding to the recursive resolution request for the third domain name to the client C3;

[0092] 4. The client C4 sends a fourth domain name recursive resolution request to the recursive resolution server N2, and the recursive resolution server N2 feeds back the domain name resolution result corresponding to the first domain name recursive resolution request to the client C4;

[0093] 5. The client C5 sends a fifth domain name recursive resolution request to the recursive resolution server N2, and the recursive resolution server N2 feeds back a domain name resolution result corresponding to the fifth domain name recursive resolution request to the client C4;

[0094] 6. The client C6 sends a sixth domain name recursive resolution request to the recursive resolution server N2, and the recursive resolution server N2 feeds back a domain name resolution result corresponding to the sixth domain name recursive resolution request to the client C6;

[0095] 7. The client C7 sends a seventh domain name recursive resolution request to the recursive resolution server N3, and the recursive resolution server N3 feeds back a domain name resolution result corresponding to the seventh domain name recursive resolution request to the client C7;

[0096] 8. The client C8 sends an eighth domain name recursive resolution request to the recursive resolution server N3, and the recursive resolution server N3 feeds back a domain name resolution result corresponding to the eighth domain name recursive resolution request to the client C8;

[0097] 9. The client C9 sends a ninth domain name recursive resolution request to the recursive resolution server N3, and the recursive resolution server N3 feeds back a domain name resolution result corresponding to the ninth domain name recursive resolution request to the client C9;

[0098] 10. The client C10 sends a tenth domain name recursive resolution request to the recursive resolution server N3, and the recursive resolution server N3 feeds back a domain name resolution result corresponding to the tenth domain name recursive resolution request to the client C10.

[0099] The secondary recursive resolution server SN determines the actual addresses of the recursive resolution servers N1, N2, and N3 according to the recursive resolution information of the ten domain names, and determines the actual addresses of the clients C1, C2, ..., C10.

[0100] The secondary recursive resolution server SN can determine the service range 1 corresponding to the recursive resolution server N1 (ie, the dotted circular range where the recursive resolution server N1 is located) according to the actual address of the recursive resolution server N1 and the actual addresses of the clients C1, C2 and C3.

[0101] The secondary recursive resolution server SN can determine the service range 2 corresponding to the recursive resolution server N2 (ie, the dotted circular range where the recursive resolution server N2 is located) according to the actual address of the recursive resolution server N2 and the actual addresses of the clients C4, C5 and C6.

[0102] The secondary recursive resolution server SN can determine the service range 3 corresponding to the recursive resolution server N3 (ie, the dotted circular range where the recursive resolution server N3 is located) according to the actual address of the recursive resolution server N3 and the actual addresses of the clients C7, C8, C9 and C10.

[0103] In this embodiment, since multiple terminals are distributed in multiple regions, multiple clients on multiple terminals send multiple domain name recursive resolution requests to the domain name resolution system. Combined with multiple domain name resolution results corresponding to the multiple domain name recursive resolution requests, multiple domain name recursive resolution information with different client distribution addresses can be generated. Compared with multiple domain name recursive resolution information generated by domain name recursive resolution requests sent by clients in local areas or a single client, the service scope of each domain name recursive resolution server in the domain name resolution system can be obtained more quickly.

[0104] In some embodiments of the present disclosure, each of the multiple domain name recursive resolution requests in step S0 includes: the network protocol address of the client, the network protocol address of the target recursive resolution server, the target address for requesting recursive domain name resolution, and field information representing the actual address of the client.

[0105] The network protocol address of the client may include the IP address of the client. The network protocol address of the target recursive resolution server may include the exit IP address of the target recursive resolution server. The field information representing the actual address of the client may include: the area code / postal code of the region where the terminal where the client is installed is located, the actual address information of the enterprise to which the terminal where the client is installed belongs, and other field information that can locate the actual address of the client. Among them, the actual address information of the enterprise to which the terminal where the client is installed belongs may include the registered address of the enterprise to which the terminal belongs and the address of the building where the enterprise to which the terminal belongs is located, etc. If the field information representing the actual address of the client includes an illegal domain name field, the illegal domain name field is converted to a legal domain name field. For example, a legal domain name may include characters, numbers or hyphens, but cannot include special characters. If there are special characters in the field information representing the actual address of the client, the field format specified by the legal domain name needs to be converted.

[0106] In this embodiment, since the actual address of the client can be quickly and accurately determined through the network protocol address of the client and the field information representing the actual address of the client, and the actual address of the target recursive resolution server can be quickly determined through the network protocol address of the target recursive resolution server, constructing a domain name recursive resolution request including the network protocol address of the client, the network protocol address of the target recursive resolution server, the target address for requesting recursive domain name resolution, and the field information representing the actual address of the client helps to improve the efficiency and accuracy of determining the service scope of the domain name recursive resolution server.

[0107] In some embodiments of the present disclosure, the domain name resolution system adopts an anycast method to provide recursive resolution services.

[0108] Anycast, also known as anycast, omnicast or arbitrary broadcast, identifies a group of hosts that provide specific services on the IP network through an anycast address. At the same time, the service accessor does not care which specific host provides the service (such as DNS or mirror service). The message accessing the address can be routed by the IP network to any host in this group of targets.

[0109] In this embodiment, since the anycast method has the characteristic of transparent service positioning at the IP layer, the domain name resolution system adopts the anycast method to provide recursive resolution service, which helps to accurately determine the location of each recursive resolution server, and further helps to accurately determine the service scope of each recursive resolution server.
