It can be understood that the execution subject of the domain name resolution detection method provided by the embodiments of the present application includes but is not limited to the domain name resolution detection apparatus.

[0045] Figure 2 The flow chart of the domain name resolution detection method provided by the embodiments of the present application is shown in Figure 2 The method comprises the following steps:

[0046] Step 101, by the test client, sequentially sending a domain name resolution request to a current domain name resolution device in the domain name resolution cluster according to a plurality of pre-generated virtual addresses, so that the current domain name resolution device obtains a resolution address according to the current virtual address and the domain name resolution request.

[0047] Step 102, performing consistency detection on the stored configuration address and the resolution address to obtain a resolution detection result.

[0048] It is worth mentioning that the acquisition, storage, use, processing, etc. of data in the technical solutions in the present application comply with the relevant provisions of national laws and regulations. The user information in the embodiments of the present application is obtained through legal and compliant channels, and the acquisition, storage, use, processing, etc. of the user information is authorized and agreed by the client.

[0049] In the technical scheme provided by the embodiment of the present application, the test client sends a domain name resolution request to the current domain name resolution device in the domain name resolution cluster in turn according to the plurality of virtual addresses generated in advance, so that the current domain name resolution device obtains a resolution address according to the current virtual address and the domain name resolution request; consistency detection is performed on the stored configuration address and the resolution address to obtain a resolution detection result, and the domain name resolution accuracy is detected from different user perspectives, so that the comprehensiveness and accuracy of the domain name resolution verification are improved, the verification difficulty is reduced, and the configuration accuracy is ensured.

[0050] Figure 3 A flowchart of another domain name resolution detection method provided by the embodiment of the present application is shown in FIG. 2, and the method comprises the following steps. Figure 3

[0051] In step 201, the server address of the test client is converted into a source address of different views by using a source address conversion technology.

[0052] In the embodiment of the present application, each step is executed by a domain name resolution detection device.

[0053] In the embodiment of the present application, the source address conversion technology refers to that when an internal network address accesses externally, the internal network IP address initiating the access is converted into a specified IP address, so that a host using a reserved IP address in the internal network can access an external network, that is, multiple hosts in the internal network can access the external network through one valid public network IP address. In the embodiment of the present application, the source address conversion is to convert the server address of the test client into a source address accessible on a specific view, and the view can be accessed through the source address.

[0054] In step 202, the source addresses of different views are respectively converted into different virtual addresses by using a load balancing strategy.

[0055] In the embodiment of the present application, the implementation principle of the DNS load balancing technology is to configure multiple IP addresses for the same host name in the DNS server, and when responding to a DNS query, the DNS server returns different resolution results in sequence according to the IP addresses of the host records in the DNS file for each query, so as to guide the access of the client to different machines, so that different clients access different servers, thereby achieving the purpose of load balancing. Specifically, the view source address is converted into a virtual address vs by using the load balancing strategy, and when the view source address is accessed, the view source address is converted into the virtual address vs, and the destination address is converted into a DNS node in a survival state.

[0056] ​Further, a virtual address control list is generated according to the virtual address and the corresponding view, and the virtual address control list is added to a current domain name resolution device (DNS) so that the current DNS obtains a resolution address according to the current virtual address and a domain name resolution request through the virtual address control list. The virtual address control list includes a plurality of virtual addresses and a plurality of virtual addresses corresponding to the view. Each view corresponding to the virtual address control list is configured on the current DNS, so that each virtual address can only enter the corresponding view for domain name resolution when accessed in subsequent detection.

[0057] In step 203, a test client sends a domain name resolution request to a current domain name resolution device (DNS) in a domain name resolution cluster according to a plurality of virtual addresses in sequence, so that the current DNS obtains a resolution address according to the current virtual address and the domain name resolution request.

[0058] In the embodiment of the application, the domain name resolution cluster includes a plurality of domain name resolution devices (DNS), and only one DNS is hung down each time for full-quantity configuration detection by using the current DNS.

[0059] In the embodiment of the application, a plurality of virtual addresses (vs) are set as DNS servers (server) during testing, and the test client sends a domain name resolution request to the DNS under the condition that the virtual address is used as the DNS server, the domain name resolution request including a domain name to be resolved; and the DNS obtains a resolution address according to the current virtual address and the domain name to be resolved.

[0060] Specifically, the current DNS matches a corresponding target view (view) according to the current virtual address through a set virtual address control list, and resolves the domain name to be resolved through the target view to obtain a resolution address.

[0061] It should be noted that the process of resolving the domain name is a relatively mature technology, and will not be described here.

[0062] In step 204, consistency detection is performed on the stored configuration address and the resolution address to obtain a resolution detection result.

[0063] In the embodiment of the application, the current DNS includes a plurality of views (view) for resolving domain names, and each view (view) is pre-configured with a corresponding domain name resolution record, and the domain name resolution record includes a configuration address.

[0064] In the embodiment of the application, step 204 specifically includes:

[0065] In step 2041, it is judged whether the configuration address and the resolution address are consistent, if yes, step 2042 is executed, and if no, step 2043 is executed.

[0066] In the embodiment of the present application, if the configuration address is consistent with the resolution address, it indicates that the configuration address configured under the view is consistent with the resolution address resolved by the current DNS, the configuration under the view is accurate, and step 2042 is continuously executed.

[0067] Step 2042, the resolution detection of the target view corresponding to the current virtual address in the current domain name resolution device is determined to be passed, and the step ends.

[0068] In the embodiment of the present application, if the configuration under the view is accurate, the domain name resolution in the current user perspective is accurate, and the resolution detection is passed.

[0069] Step 2043, if the configuration address is inconsistent with the resolution address, the resolution detection of the target view corresponding to the current virtual address in the current domain name resolution device is determined to fail.

[0070] In the embodiment of the present application, if the configuration under the view is incorrect, the domain name resolution in the current user perspective is incorrect, and the resolution detection fails, and the step ends.

[0071] Step 205, if the current domain name resolution device completes the domain name resolution detection, it is judged whether there is a next domain name resolution device of the current domain name resolution device in the domain name resolution cluster, if yes, step 206 is continuously executed, and if no, the flow ends.

[0072] In the embodiment of the present application, the domain name resolution cluster includes multiple domain name resolution devices (DNS), only one DNS is hung down each time, and the domain name resolution detection needs to be performed on each DNS in the domain name resolution cluster respectively. Assuming that there are M DNS devices in the domain name resolution cluster, the DNS nodes under each vs are sequentially set as DNS 1 to DNS M, only one DNS j is hung down each time, then the single DNS device full configuration detection flow is entered, the full view configuration of the DNS j is verified, and finally the full M DNS node configuration is completely verified.

[0073] Specifically, if all virtual addresses complete the domain name resolution, it indicates that the current DNS completes the domain name resolution detection. It is judged whether there is a next domain name resolution device of the current DNS in the domain name resolution cluster, if yes, it indicates that the current DNS is not the last DNS, and step 206 is continuously executed, and if no, it indicates that the current DNS is the last DNS, and the full user domain name resolution detection of the domain name resolution cluster is completed, and the flow ends.

[0074] Step 206, the next domain name resolution device in the domain name resolution cluster is determined as the current domain name resolution device, and step 203 is continuously executed.

[0075] Specifically, if the current domain name resolution device completes the domain name resolution test, the next domain name resolution device in the domain name resolution cluster will be identified as the current domain name resolution device, and the full configuration test process for a single DNS device will be entered, and step 203 will continue to be executed.

[0076] In this embodiment of the invention, when the test client accesses different virtual addresses, the DNS resolution will access the corresponding view, so that the test client can reach the corresponding view for resolution by accessing different virtual addresses, thereby simulating the resolution of different real users accessing the domain name, and thus verifying whether the configuration is consistent with the user's needs.

[0077] In this embodiment of the invention, by configuring virtual addresses for access control of different views, it is possible to simulate real users in different regions to initiate domain name resolution requests through a single test client, compare and verify resolution records, and verify the accuracy of domain name resolution from the perspective of all users; it can automatically verify the accuracy of domain name configuration of all DNS nodes in the domain name resolution cluster without the need for manual verification on each machine, reducing human error and improving verification efficiency and accuracy.

[0078] In the technical solution of the domain name resolution detection method provided in this embodiment of the invention, a test client sends domain name resolution requests to the current domain name resolution device in the domain name resolution cluster in sequence according to multiple pre-generated virtual addresses, so that the current domain name resolution device can obtain the resolution address based on the current virtual address and the domain name resolution request; the consistency of the stored configuration address and the resolution address is checked to obtain the resolution detection result. By simulating the domain name resolution accuracy detection from different user perspectives, the comprehensiveness and accuracy of domain name resolution verification can be improved, the verification difficulty can be reduced, and thus the configuration accuracy can be guaranteed.

[0087] The adding unit 16 is configured to add the virtual address control list to the current domain name resolution device, so that the current domain name resolution device obtains a resolution address according to the current virtual address and the domain name resolution request through the virtual address control list.

[0088] In the embodiment of the present application, the detecting unit 12 is specifically configured to determine that the resolution detection of the target view corresponding to the current virtual address in the current domain name resolution device is passed if the configuration address is consistent with the resolution address; and determine that the resolution detection of the target view corresponding to the current virtual address in the current domain name resolution device fails if the configuration address is inconsistent with the resolution address.

[0089] In the embodiment of the present application, the device further comprises a determining unit 17.

[0090] The determining unit 17 is configured to determine the next domain name resolution device in the domain name resolution cluster as the current domain name resolution device if the domain name resolution detection of the current domain name resolution device is completed, and trigger the control unit 11 to continue to execute the step of sequentially sending the domain name resolution request to the current domain name resolution device in the domain name resolution cluster according to the pre-generated multiple virtual addresses through the test client.
