Description
Technical Field
The present application relates to the field of internet information technology processing, and in particular, to a synchronization method and apparatus for domain name resolution.
Background
With the development of Internet technology, people can locate computers in the Internet through an Internet Protocol (IP) address, that is, when an IP address is obtained, a computer in the Internet corresponding to the IP address can be determined through the IP address.
However, since IP addresses are not easily remembered by people, it is proposed to replace IP addresses by domain names. However, the computer corresponding to the IP address replaced by the domain name cannot be directly accessed by the domain name. Therefore, when a domain name is acquired, the acquired domain name needs to be converted into an IP address through a domain name resolution process; and accessing the computer corresponding to the IP address by using the obtained IP address.
Domain Name resolution generally relies on a Domain Name Service (DNS) system to map Domain names to IP addresses. The domain name service system is a distributed database based on TCP/IP applications that provides translation between host names and IP addresses. Typically including public DNS and authoritative DNS.
When receiving a domain name query request, the public DNS queries a resolution result of a local cache; if the resolution result corresponding to the domain name contained in the domain name query request is queried, returning the queried resolution result to the user; if the resolution result corresponding to the domain name included in the domain name query request is not queried, the domain name to be queried is carried in the query request and is sent to a last-layer DNS (for example, a local DNS), and the last-layer DNS is requested to resolve the domain name included in the query request. When the DNS of the upper layer receives the query request, determining whether the domain name to be queried can be analyzed, and if the domain name can be directly analyzed, returning an analysis result; if the domain name can not be directly analyzed, whether the analysis result corresponding to the domain name can be determined or not is determined by inquiring the domain name analysis result of the local cache.
And when the resolution result corresponding to the domain name is not inquired, carrying the domain name to be inquired in the inquiry request and sending the inquiry request to the DNS of the next upper layer, and sequentially executing the operations until the resolution result corresponding to the domain name is inquired, and finishing the operation.
The authoritative DNS refers to a server which is authorized to analyze the domain name, and has the function of authorizing the analysis result to other DNS. For example: the top level server of the domain name com may authorize the authoritative server of the domain name abc.com to be ns.abc.com. The authoritative DNS sends the resolution results to the public DNS so that the public DNS stores the received resolution results locally.
However, in practical applications, since the time for each public DNS to acquire the resolution result of the authoritative DNS is different, the time for the authoritative DNS to acquire the resolution result is different on different public DNS, and there is a certain delay, which greatly reduces the resolution efficiency of the public DNS for domain name resolution.

Various embodiments of the present application are described in further detail below with reference to the figures of the specification. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart of a synchronization method for domain name resolution according to an embodiment of the present disclosure. The method may be as follows. The execution subject in the embodiment of the present application may be an application client, or may also be a third-party server, which is not limited herein.
Step 101: and the third party server receives the resolution result sent by the authoritative DNS device.
And sending the analysis result after the analysis result cached in the authoritative DNS equipment is updated.
In step 101, the third-party server may perform information interaction with an authoritative DNS device and may also perform information interaction with a public DNS device, respectively.
For example: the third party server utilizes a Hypertext Transfer Protocol (English; abbreviated as HTTP) to carry out information interaction with the authoritative DNS equipment; and performing information interaction with the public DNS device by using HTTP.
Once the analysis result is updated in the authoritative DNS equipment, the authoritative DNS equipment actively sends the updated analysis result to the third-party server.
In addition, when the third-party server acquires the domain name to be resolved, the domain name to be resolved is carried in the resolution production request and is sent to the authoritative DNS device.
And the resolution production request is used for requesting the authoritative DNS equipment to resolve the domain name to be resolved and returning a resolution result.
Specifically, when receiving the domain name to be resolved, the third-party server carries the domain name to be resolved in a resolution production request and sends the domain name to be resolved to an authoritative DNS device so as to request the authoritative DNS device to resolve the domain name to be resolved and return a resolution result.
Specifically, when receiving a domain name to be resolved, the third-party server sends an analysis result query request to an authoritative DNS device, where the analysis result query request includes the domain name to be resolved, and the analysis result query request is used to determine whether a corresponding analysis result exists in the received domain name to be resolved.
And when the authoritative DNS equipment determines that the domain name to be analyzed does not have a corresponding analysis result, sending the query result to a third-party server, and at the moment, carrying the domain name to be analyzed in an analysis production request by the third-party server and sending the domain name to be analyzed to the authoritative DNS equipment.
When the authoritative DNS equipment receives the analysis production request, the domain name to be analyzed is analyzed to obtain an analysis result corresponding to the domain name to be analyzed, and the analysis result in the cache is updated.
At this time, the authoritative DNS device sends the resolution result corresponding to the domain name to be resolved to the third-party server.
In addition, since the authoritative DNS device resolves the domain name to be resolved when receiving the resolution production request, obtains a resolution result corresponding to the domain name to be resolved, and updates the internally cached resolution result, the authoritative DNS device may only send the resolution result corresponding to the domain name to be resolved to the third-party server, or may send the updated resolution result to the third-party server.
That is, the resolution production request sent by the third-party server may be regarded as a trigger condition for the authoritative DNS device to send the resolution result to the third-party server.
It should be noted that the resolution result sent by the authoritative DNS device to the third-party server may be a currently valid resolution result, or may be a resolution result valid within a set time range.
In addition, the manner of receiving the resolution result sent by the authoritative DNS device by the third party server may also be:
and the third party server sends a query request to the authoritative DNS equipment in real time.
Wherein the query request is used for requesting the authoritative DNS device to send the updated resolution result.
And the third party server receives the query result sent by the authoritative DNS equipment.
Wherein, the query result comprises a resolution result updated by the authoritative DNS device.
It should be noted that "the latest updated resolution result" may be understood as a resolution result after an update operation that is closest to the time when the authoritative DNS device receives the query request.
Step 102: and the third party server sends the received resolution result to different public DNS equipment.
In step 102, when receiving a resolution result sent by an authoritative DNS device, the third-party server sends the received resolution result to a different public DNS device by using HTTP.
Therefore, for the analysis results in the internal cache of the public DNS equipment, the analysis results are updated in real time according to the updated analysis results of the authoritative DNS equipment obtained by the third-party server in real time without depending on the set update time, so that the effective analysis results in the cache of the public DNS equipment are ensured to be consistent with the effective analysis results in the authoritative DNS equipment, the problem that the effective time of the analysis results is delayed due to the fact that cache refreshing time in the public DNS equipment is inconsistent is solved, and the analysis efficiency of the public DNS in performing domain name analysis is effectively improved.
Optionally, when the received resolution result is sent to a different public DNS device, the method further includes:
and sending the received analysis result to the client equipment corresponding to each public DNS equipment, so that the client equipment stores the received analysis result locally.
Specifically, sending the received resolution result to the client device corresponding to each public DNS device includes:
and sending heartbeat data packets to the client device corresponding to each public DNS device.
Wherein the heartbeat data packet is used to determine whether the client device is online.
And when a response data packet sent by the client equipment is received within a first set time range, sending the received analysis result to the client equipment.
When the response data packet sent by the client device is not received within a first set time range, the method further comprises the following steps:
and sending a heartbeat data packet to the client equipment at regular time, and sending the analysis result received in a second set time range to the client equipment when receiving a response data packet sent by the client equipment.
It should be noted that the first set time range may be determined according to the effective time of the heartbeat data packet, or may be determined according to actual needs; the second set time range is greater than the first set time range.
That is, when it is determined that the client device is not online, the heartbeat data packet is sent to the client device at regular time, and when the response data packet sent by the client device is received again, the third-party server may receive the analysis result sent by the authoritative DNS device for multiple times, so that the third-party server may send the analysis result during the period from the time that the client device is not online to the time that the client device is online to the time that the third-party server is online to the client device, so as to ensure that the analysis result inside the client device is consistent with the analysis result inside the authoritative DNS device.
According to the scheme of the embodiment of the application, the analysis result sent by the authoritative domain name service DNS equipment is received, and the analysis result is sent after the analysis result cached in the authoritative DNS equipment is updated; and sending the received resolution result to different public DNS equipment. Therefore, when the authoritative DNS equipment resolves the domain name to generate a new resolving result, the resolving result which is newly validated in the authoritative DNS equipment is sent to the public DNS equipment through the third equipment between the authoritative DNS equipment and the public DNS equipment, the consistency of the validating resolving result in the public DNS equipment cache and the validating resolving result in the authoritative DNS equipment is ensured, the problem that the validating time of the resolving result is delayed due to the fact that cache refreshing time in the public DNS equipment is different is solved, and the resolving efficiency of the public DNS equipment for performing domain name resolution is effectively improved.
