Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
When the domain name resolution content is changed, the updating of the domain name resolution needs to be completed, and the updating of the domain name resolution can also be called as the effect of the domain name resolution, that is, the client end finally obtains the IP address in the mapping relation corresponding to the changed domain name.
In the related art, for the IP address corresponding to the domain name that is changed, the IP address needs to be issued to each layer of the DNS domain name system layer by layer, and finally issued to the client, which results in a longer update time of domain name resolution, generally more than 10 minutes. When the IP address corresponding to the domain name is just changed, the layer-by-layer delivery to each layer of the DNS domain name system is required, so that the change of the IP address corresponding to the domain name is likely to occur, but the result of the client query is the IP address corresponding to the domain name that was changed last time. In this case, the update efficiency of domain name resolution is more remarkable.
Based on the above, the invention provides a domain name resolution updating method, a device, electronic equipment and a storage medium, so that the updating efficiency in domain name resolution updating is improved.
The following first describes a domain name resolution updating method provided by the embodiment of the present invention from the perspective of a management server.
The method for updating domain name resolution provided by the embodiment of the invention can be applied to a management server, wherein the management server is a server for managing each DNS server, and the client is functional software running on electronic equipment. In a specific application, the electronic device may be a terminal device such as a smart phone, a tablet computer, etc. And, the client may be any client having a requirement for querying domain name resolution content, for example: the client may be an entertainment client, a news client, an instant messaging client, and so on.
The method for updating domain name resolution provided by the embodiment of the invention can comprise the following steps:
When detecting the change of the IP address in the mapping relation corresponding to any domain name, determining the changed IP address to obtain the IP address to be updated; wherein, the mapping relation corresponding to the domain name records the domain name and at least one corresponding IP address, each IP address corresponds to a designated geographic area, and when clients in the designated geographic area corresponding to each IP address resolve the domain name, the resolution content obtained is the IP address;
issuing update notification for any domain name to each DNS server; the update notification is used for indicating that the target geographic area corresponds to the IP address to be updated; the target geographic area is a designated geographic area corresponding to the changed IP address;
And sending a resolution content update notification for any domain name to each client in the target geographic area, so that each client requests the IP address to be updated from any server in each DNS server after receiving the resolution content update notification.
According to the updating scheme of domain name resolution provided by the embodiment of the invention, when domain name resolution is updated, a client side does not need to inquire IP addresses corresponding to domain names layer by layer from a server side; after the IP address in the mapping relation corresponding to any domain name is changed, the management server determines the changed IP address to obtain the IP address to be updated; and then issuing an update notification for any domain name to each DNS server, and directly notifying each client in the target geographic area, so that each client requests target resolution content from any server of each DNS server. Therefore, the problem of low efficiency in domain name resolution updating in the related technology can be solved by the scheme, so that the updating efficiency of domain name resolution is improved.
The method for updating domain name resolution provided by the embodiment of the invention from the management server side is specifically described below with reference to the accompanying drawings.
As shown in fig. 1, the method for updating domain name resolution provided by the embodiment of the present invention is applied to a management server, and the method may include the following steps S101 to S103:
s101: when detecting the change of the IP address in the mapping relation corresponding to any domain name, determining the changed IP address to obtain the IP address to be updated;
Wherein, the mapping relation corresponding to the domain name records the domain name and at least one corresponding IP address, each IP address corresponds to a designated geographic area, and when clients in the designated geographic area corresponding to each IP address resolve the domain name, the resolution content obtained is the IP address;
When the change of the IP address in the mapping relation corresponding to any domain name is detected, the update of domain name resolution is required, and the changed IP address can be determined first to obtain the IP address to be updated. In one implementation, if a change instruction of an IP address in a mapping relationship corresponding to any domain name sent by a configuration platform is detected, the changed IP address is resolved from the change instruction, and an IP address to be updated is obtained. That is, if the management server detects a change instruction of the IP address in the mapping relationship corresponding to any domain name, which is sent by the configuration personnel through the configuration platform, and indicates that the IP address needs to be updated, the management server can determine the changed IP address, and obtain the IP address to be updated.
The IP address change in the mapping relationship corresponding to any domain name may be: the IP address in the mapping relation corresponding to any domain name is modified or increased.
It may be appreciated that, by way of example, in one implementation, the instruction for changing the IP address in the mapping relationship corresponding to any domain name may include:
The instruction for modifying the IP address of one or more geographic areas corresponding to a domain name, where, correspondingly, the changing the IP address in the mapping relationship corresponding to any domain name includes: any domain name is modified for the IP address of at least one geographic area. For this implementation, if an instruction for modifying the IP address of one or more geographic areas corresponding to a domain name is detected, the modified IP address of at least one geographic area corresponding to the domain name may be determined, so as to obtain the IP address to be updated. For example, if the geographic area corresponding to the domain name a includes: region 1, region 2, and region 3, and each geographic region contains a different IP address: 1.1.1.1, 2.2.2.2 and 3.3.3.3; if the geographical area corresponding to the domain name A is: if the IP addresses of the area 1 and the area 2 are modified to be 2.2.2.2 and 1.1.1.1, the IP addresses 2.2.2.2 and the IP addresses 1.1.1.1 can be determined as modified IP addresses, and the IP addresses to be updated for the area 1 and the area 2 are obtained. For example, in another implementation, the instruction for changing the IP address in the mapping relationship corresponding to any domain name may include:
For a domain name, adding an instruction of a corresponding relation between the domain name and an IP address in a certain geographical area, wherein the changing of the IP address in the mapping relation corresponding to any domain name includes: the IP address for at least one geographic area is increased. For this implementation, if a domain name is currently accessible only through clients in a specific geographic area, that is, the domain name only has an IP address for the specific geographic area, the IP addresses for other geographic areas may be increased, so that clients in other areas may access the domain name; at this time, the added IP address of at least one geographical area may be determined as the changed IP address, to obtain the IP address to be updated. Exemplary: the domain name B can only be accessed in China, and for a foreign authorized geographic area 4, the IP address aiming at the geographic area 4 can be increased so that a user can access the domain name B abroad; and the IP address of the geographical area 4 with the domain name B added can be directly determined as the changed IP address, so as to obtain the IP address to be updated.
The above-described manner of determining the target domain name in which the domain name resolution content is changed is merely an example, and should not be construed as limiting the present invention.
S102: issuing update notification for any domain name to each DNS server;
the update notification is used for indicating that the target geographic area corresponds to the IP address to be updated; the target geographic area is a designated geographic area corresponding to the changed IP address;
After obtaining the IP address to be updated, since the IP address to be updated corresponds to the target geographic area, and the IP address to be updated may correspond to the IP address to be updated for each geographic area, an update notification for any domain name and indicating that the target geographic area corresponds to the IP address to be updated may be issued to each DNS server. Thus, for the target geographic area, the subsequent steps are performed to implement the updating of domain name resolution of the target geographic area.
In order to realize the instant update of domain name resolution, each level of the DNS domain name system multi-layer structure needs to be skipped, so that the management server can firstly issue the IP address to be updated for any domain name to each DNS server, and the client can directly inquire the IP address to be updated from each DNS server.
It may be appreciated that in one implementation, the change of the IP address in the mapping relationship corresponding to any domain name includes: modifying the IP address in the mapping relation corresponding to any domain name; accordingly, the target geographic area includes: the designated geographic area to which the modified IP address corresponds occurs. For example, the above-described designated geographical area in which the correspondence between the domain name a and the IP address is modified, the area 1 and the area 2 may be regarded as target geographical areas.
In another implementation, the changing the IP address in the mapping relationship corresponding to any domain name includes: increasing the IP address in the mapping relation corresponding to any domain name; accordingly, the target geographic area includes: the designated geographic area to which the added IP address corresponds occurs. For example, the above-described designated geographical area in which the correspondence between the domain name B and the IP address is increased, the area 4 may be a target geographical area.
In addition, the specified geographic area corresponding to the changed IP address in each geographic area is determined as the target geographic area, so that the changed IP address to be updated can be accurately issued to the target geographic area, the resource waste is reduced, and the updating efficiency of domain name resolution updating is improved.
S103: sending a resolution content update notification for any domain name to each client in the target geographic area, so that each client requests the IP address to be updated from any server in each DNS server after receiving the resolution content update notification;
In order to complete the instant update of the domain name resolution, after the change of the IP address in the mapping relationship corresponding to any domain name is completed, the client needs to directly query and save the changed IP address to be updated. At this time, the management server may send a notification of updating the resolution content for any domain name to each client in the target geographic area, where the client knows that the IP address in the mapping relationship corresponding to any domain name is updated, and may request any server in each DNS server for the IP address to be updated, so that the instant update of domain name resolution is completed.
For example, in one implementation, the target success rate may be detected first, if it is greater than a preset threshold; wherein, the target success rate is: the success rate of updating notification aiming at any domain name is issued to each DNS server; and if the judgment result is yes, the current change is considered to be successful, and the step of sending the analysis content update notification aiming at any domain name to each client in the target geographic area is executed. Thereby completing the instant update of domain name resolution.
According to the updating scheme of domain name resolution provided by the embodiment of the invention, when domain name resolution is updated, a client side does not need to inquire IP addresses corresponding to domain names layer by layer from a server side; after the IP address in the mapping relation corresponding to any domain name is changed, the management server determines the changed IP address to obtain the IP address to be updated; and then issuing an update notification for any domain name to each DNS server, and directly notifying each client in the target geographic area, so that each client requests target resolution content from any server of each DNS server. Therefore, the problem of low efficiency in domain name resolution updating in the related technology can be solved by the scheme, so that the updating efficiency of domain name resolution is improved.
An update method for domain name resolution provided from the client side according to an embodiment of the present invention is described below with reference to fig. 2.
As shown in fig. 2, the method for updating domain name resolution provided in the present embodiment is applied to a client, and the method may include the following steps S201 to S202:
S201: receiving an analysis content update notification for any domain name sent by a management server;
wherein, the domain name resolution content update notification is: the management server side sends update notification for any domain name to each DNS server and then sends the update notification to each client side in a target geographic area; the domain name of any domain is the domain name with changed IP address in the corresponding mapping relation, and the IP address to be updated is the changed IP address; the update notification is used for indicating that the target geographic area corresponds to an IP address to be updated; the target geographic area is a designated geographic area corresponding to the changed IP address; the mapping relation corresponding to the domain name is recorded with the domain name and at least one corresponding IP address, each IP address corresponds to a specified geographic area, and when a client in the specified geographic area corresponding to each IP address resolves the domain name, the resolution content obtained is the IP address;
when the management server sends a notification of updating the resolution content for any domain name to the client, the client knows that the corresponding relationship between the domain name and the IP address of the corresponding geographical area is changed, and in order to complete updating of domain name resolution, a subsequent step needs to be executed.
For example, in one implementation, the client receiving the resolution content update notification for any domain name sent by the management server may be a DNS program on the client.
S202: requesting the IP address to be updated from any one of the DNS servers;
after receiving the notification that the management server sends the update of the resolution content for any domain name, the client can send a request to any server in all DNS servers to acquire and store the IP address to be updated.
For example, in one implementation, the DNS program of the client may issue a request to any of the various DNS servers to query for an IP address to be updated and update to the local cache.
According to the updating scheme of domain name resolution provided by the embodiment of the invention, when domain name resolution is updated, a client side does not need to inquire IP addresses corresponding to domain names layer by layer from a server side; after the IP address in the mapping relation corresponding to any domain name is changed, the management server determines the changed IP address to obtain the IP address to be updated; and then issuing an update notification for any domain name to each DNS server, and directly notifying each client in the target geographic area, so that each client requests target resolution content from any server of each DNS server. Therefore, the problem of low efficiency in domain name resolution updating in the related technology can be solved by the scheme, so that the updating efficiency of domain name resolution is improved.
In addition, any domain name corresponds to an IP address for each geographic region, i.e., domain name resolution is divided by geographic region. By dividing the domain name into geographical areas, the IP serving the client of each geographical area can be flexibly set for the domain name. And each geographical area corresponds to an IP range, i.e. if the IP of a client belongs to this IP range, the client will automatically divide into this geographical area.
The domain name configuration is maintained in conjunction with a tree structure, dividing the geographic area. For ease of understanding, the following description is provided in connection with fig. 3.
The root area in fig. 3 must set IP, and other areas automatically acquire IP from the upper layer if IP is not set.
Illustratively, if the IP of the root area is 6.6.6.6 and the asian area is not set, the IP of the upper layer, that is, IP6.6.6.6 of the root area is automatically acquired, and the IP of the asian area is 6.6.6.6.
By dividing the geographic areas, the geographic areas affected by the change of the IP address in the mapping relation corresponding to any domain name can be clearly determined, and the affected geographic areas (corresponding to the target geographic areas) can be notified in detail. And, when update notifications are sent to each client in the affected geographic area, all affected clients are notified. For example: if the IP address in the mapping relationship corresponding to any domain name is changed in the geographic area of china, each area of china is notified, for example: east China, north China, and cities in North China and east China, such as Beijing, shanghai, etc. The client corresponding to each affected region may request the target resolution content from any one of the DNS servers, thereby completing the updating of domain name resolution.
To facilitate understanding of the solution, a specific embodiment is described below in connection with fig. 4.
The embodiment can realize the updating method of domain name resolution provided by the embodiment of the invention through interaction of a domain name resolution management platform, domain name resolution service, center service, a message system and a client DNS program.
The domain name resolution management platform (corresponding to the configuration platform) is distinguished according to geographic positions, a tree structure (such as Asia-China-UNICOM-North China-Beijing, as shown in figure 3) can be constructed by combining operators and the geographic positions, one domain name can be provided with an IP (Internet protocol) at each layer of the tree structure, and a child node can automatically use the IP of a father node if not provided with the IP; the platform maintains the correspondence between the domain name and the IP (e.g., www.xxx.com domain name, service provided in beijing using 1.1.1.1, service provided in the open sea using 2.2.2.2); the platform also provides query and modification pages for administrator operations (e.g., change www.xxx.com to 1.2.3.4 in Beijing's IP, i.e., modify domain name); the platform supports output of full configuration policies (IP of all domain names in all areas) and incremental change policies (e.g. www.xxx.com IP in beijing is changed from 1.1.1.1 to 1.2.3.4).
The center service (corresponding to the management service end) connects the platform and the domain name resolution service, synchronously updates the strategy of the incremental change of the platform to the domain name resolution service cluster (for example, the IP of www.xxx.com in Beijing is changed to 1.2.3.4 on the platform, the platform informs the center service, and the center service distributes the updated data to each DNS domain name resolution server and gathers the updated result); after the updated data (corresponding to the IP address to be updated) is notified to the DNS domain name resolution server, if the success rate (corresponding to the target success rate) is higher than the set threshold, the analysis change details are notified to the clients corresponding to the geographic location (for example, the clients in beijing area are notified if beijing is modified, and the clients in the north of the china and all areas without independent resolution below the north of the china are notified if north of the china is modified).
Domain name resolution service (corresponding to each DNS server) can update its own local policy (i.e. update IP address to be updated, support incremental modification) according to the full or incremental policy; the domain name resolution service also provides a domain name resolution query service (e.g., resolution of user query www.xxx.com in Beijing yields 1.1.1.1, and user query in Shanghai yields 2.2.2.2).
The message system notifies the affected clients according to the change details, i.e. notifies the clients (such as APP on the mobile phone) of the updated information of the domain name.
The client DNS program, upon receipt of the notification, proactively queries the domain name resolution service for the latest IP and updates to the local cache (i.e., query resolution).
