Description

Domain name resolution methods, devices and computer equipment

[0001] This application claims priority to Chinese Patent Application No. 202410565238.2, filed on May 6, 2024, entitled "Domain Name Resolution Method, Apparatus, Computer Equipment and Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, specifically to a domain name resolution method, apparatus, and computer equipment. Background Technology

[0003] Connecting to the internet via Wi-Fi is becoming increasingly common, and modern life is inseparable from Wi-Fi technology. Currently, various internet-connected applications on terminal devices need to resolve the internet protocol address (IP address) corresponding to the domain name during use, and then access the network based on the IP address. Technical issues

[0004] The existing domain name resolution process typically includes the following steps: An application constructs a network access request using a domain name. Upon receiving the request, the operating system first checks its local cache or DNS cache for the corresponding IP address. If neither cache contains the IP address, it sends a domain name resolution request to a pre-defined domain name server to retrieve the IP address. Because the IP address returned by the domain name server is valid for a very short time, network applications on the terminal device need to go through the domain name resolution process again the next time they access the network, resulting in slow network speeds. Technical solutions

[0005] This application provides a domain name resolution method, apparatus, and computer equipment, which can improve the domain name resolution speed and the network speed of applications.

[0006] Firstly, this application provides a domain name resolution method, including:

[0007] Retrieve the cache time corresponding to the cached domain name in the target cache. The target cache includes the cached domain name and the IP address corresponding to the cached domain name.

[0008] Candidate domains are determined from cached domains based on cache time. Candidate domains are those whose cache time has reached the first preset time.

[0009] Obtain the access frequency corresponding to the candidate domain name. If the access frequency reaches the preset frequency threshold, send the first domain name resolution request for the candidate domain name to the preset domain name server.

[0010] Obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the updated IP address.

[0016] In some implementation schemes of this application, the domain name types include a first type, a second type, and a third type. The first type of domain name is a pre-set known domain name, the second type of domain name is a non-aging application domain name that the user pre-sets according to their needs, and the third type of domain name is other domain names besides the first type and the second type of domain names.

[0036] Save the target domain name and its corresponding IP address to the target cache.

[0037] In some embodiments of this application, after sending a second domain name resolution request for the target domain name to a preset public domain name server, the process includes:

[0038] If the public domain name server fails to resolve the domain name, a second domain name resolution request is sent to the domain name server assigned by the router, and the IP address corresponding to the target domain name returned by the domain name server assigned by the router based on the second domain name resolution request is obtained.

[0039] Returns the IP address corresponding to the target domain name to the target application.

[0088] This application provides a domain name resolution method, apparatus, computer device, and storage medium, which will be described in detail below.

[0089] Please refer to Figure 1. Figure 1 is a schematic diagram of a domain name resolution system provided in an embodiment of this application. The domain name resolution system may include a computer device 100 and a domain name server 200 that is communicatively connected to the computer device 100. The computer device 100 integrates a domain name resolution device.

[0090] In this embodiment, the computer device 100 is mainly used to obtain the cache time corresponding to the cached domain name in the target cache, the target cache including the cached domain name and the IP address corresponding to the cached domain name; determine the candidate domain name from the cached domain name based on the cache time, the candidate domain name is the domain name whose cache time has reached a preset first time; obtain the access frequency corresponding to the candidate domain name, if the access frequency reaches a preset frequency threshold, send a first domain name resolution request for the candidate domain name to a preset domain name server; obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the updated IP address, which can improve the domain name resolution speed and the network speed of the application.

[0092] In this embodiment of the application, the domain name server 200 can be an independent server, or a server network or server cluster composed of servers. For example, the domain name server 200 includes, but is not limited to, a public domain name server (public DNS server), an HTTP DNS server based on the HTTP protocol, etc.

Other application environments may include more or fewer computer devices than those shown in Figure 1. For example, only one computer device is shown in Figure 1. It is understood that the domain name resolution system may also include one or more other services, which are not specifically limited here.

[0094] In addition, as shown in Figure 1, the domain name resolution system may also include a storage device for storing data, such as domain name information, such as the cache time corresponding to the cached domain name, the IP address corresponding to the cached domain name, and frequency information, such as access frequency and frequency threshold.

[0095] It should be noted that the schematic diagram of the domain name resolution system shown in Figure 1 is merely an example. The domain name resolution system and scenario described in this application are intended to more clearly illustrate the technical solutions of this application and do not constitute a limitation on the technical solutions provided in this application. As those skilled in the art will know, with the evolution of the domain name resolution system and the emergence of new business scenarios, the technical solutions provided in this application are also applicable to similar technical problems.

[0096] First, this application provides a domain name resolution method. The execution subject of this domain name resolution method is a domain name resolution device, which is applied to a computer device. The domain name resolution method includes: obtaining the cache time corresponding to the cached domain name in the target cache, the target cache including the cached domain name and the IP address corresponding to the cached domain name; determining the candidate domain name from the cached domain name based on the cache time, the candidate domain name being the domain name whose cache time has reached a preset first time; obtaining the access frequency corresponding to the candidate domain name, and if the access frequency reaches a preset frequency threshold, sending a first domain name resolution request for the candidate domain name to a preset domain name server; obtaining the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and updating the IP address corresponding to the candidate domain name based on the updated IP address.

[0097] Figure 2 shows a flowchart of an embodiment of the domain name resolution method in this application. The domain name resolution method may include the following steps S201 to S204, as detailed below:

[0098] Step S201: Obtain the cache time corresponding to the cached domain name in the target cache. The target cache includes the cached domain name and the IP address corresponding to the cached domain name.

[0099] The target cache is a pre-defined local cache on the computer device. After the computer device boots up, it can load a pre-defined mapping file from a fixed path in the operating system and save the mapping file in the target cache. This mapping file contains a pre-defined mapping relationship between domain names and IP addresses, which users can modify according to their actual needs.

[0100] The target cache includes the cached domain name and its corresponding IP address. The cached domain name is the domain name cached in the target cache. For example, after saving the mapping file in the target cache, the cached domain name includes the domain name preset in the mapping file. It should be noted that when the target application sends a network access request carrying the target domain name to the computer device, if a cached domain name matching the target domain name exists in the target cache, the computer device can directly return the IP address corresponding to the cached domain name matching the target domain name to the target application without going through the existing domain name resolution process. This not only improves the network speed of the target application but also avoids the waste of system resources caused by repeated domain name resolution processes.

[0101] Cache time refers to the duration for which the IP address corresponding to the cached domain name has been retained in the target cache. It is the time difference between the time when the IP address corresponding to the cached domain name was saved to the target cache and the current time, or the time difference between the time when the IP address corresponding to the cached domain name was updated and the current time. For example, if the IP address A corresponding to the cached domain name A was saved to the target cache at 18:10 and the current time is 18:15, then the cache time corresponding to the cached domain name A is 5 minutes.

[0102] Step S202: Determine candidate domains from the cached domains based on the cache time. The candidate domains are the domains whose cache time has reached the preset first time.

[0103] While storing cached domain names and IP addresses in the target cache can improve application network speed, it consumes memory and impacts cache performance. In severe cases, it may cause memory overflow, leading to cache system crashes. To improve the performance of the target cache, this embodiment sets an aging time for cached domain names and their IP addresses. The aging time refers to the maximum time that the cached domain names and their IP addresses can live. When the aging time is reached, the cached domain names and their IP addresses will be deleted from the target cache.

[0104] The first time is a pre-set threshold used to measure whether the cache time is about to reach the aging time. The first time can be set according to user needs. For example, when the aging time is T1, the first time can be set to... wait.

[0105] It should be noted that the target cache can include multiple cache domains. The initial time for each cache domain can be set to the same or different. For example, the initial time for each cache domain can be set to... For example, the first time corresponding to the cached domain A is set to The first time corresponding to cache domain B is set The first time corresponding to cache domain B is set

[0106] Candidate domains are those cached domains whose cache time has reached a preset first time. When determining candidate domains from cached domains based on cache time, the cache time can be compared with the first time, and the candidate domains can be determined based on the comparison result. For example, candidate domains are those cached domains whose cache time has reached five minutes.

[0107] Step S203: Obtain the access frequency corresponding to the candidate domain name. If the access frequency reaches the preset frequency threshold, send the first domain name resolution request for the candidate domain name to the preset domain name server.

[0108] Access frequency refers to the number of times a candidate domain is accessed within a unit of time. Access frequency can be determined based on the number of times a candidate domain is accessed in a recent period. The frequency threshold is a pre-set threshold used to measure whether a candidate domain is frequently accessed. The frequency threshold can be set according to actual needs. For example, if the frequency threshold is set to 3, and the access frequency of the candidate domain is greater than or equal to 3, it indicates that the candidate domain is accessed frequently. If the access frequency of the candidate domain is less than 3, it indicates that the candidate domain is accessed frequently.

[0109] To improve the access speed of frequently accessed domains, this embodiment selects candidate domains from the cached domains whose caching time has reached a preset first time, obtains the access frequency of the candidate domains, and compares the access frequency with a preset frequency threshold. If the access frequency reaches the preset frequency threshold, it indicates that the candidate domain is accessed more frequently, and then sends a first domain name resolution request for the candidate domain to the preset domain name server.

[0110] A Domain Name Server (DNS) is a server used to translate domain names into their corresponding IP addresses. The DNS maintains a table for resolving domain names and their corresponding IP addresses. In the first domain name resolution request mentioned above, candidate domain names are carried. After receiving the first domain name resolution request, the DNS can obtain the IP address corresponding to the candidate domain name carried in the first domain name resolution request by querying the mapping relationship between domain names and IP addresses recorded in the table.

[0111] The domain name servers used in current domain name resolution processes are typically assigned by the routers to which computer devices are connected. Router-assigned domain name servers are unreliable; when faced with domain name hijacking, they can easily obtain unpredictable IP addresses, leading to the computer device accessing unpredictable resources. To address these issues, the domain name server used in step S203 can be a public domain name server (public DNS server) or an HTTP-based domain name server (HTTPDNS server). Compared to the current use of router-assigned domain name servers for domain name resolution, this avoids domain name hijacking and ensures the accuracy of the obtained IP address.

[0112] Step S204: Obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the updated IP address.

[0113] After receiving the first domain name resolution request, the domain name server resolves the candidate domain name carried in the request to obtain the updated IP address corresponding to the candidate domain name, and returns the updated IP address to the computer device. Upon receiving the updated IP address returned by the domain name server, the computer device updates the IP address corresponding to the candidate domain name in the target cache based on the updated IP address, thus enabling the application to quickly obtain the IP address corresponding to the candidate domain name the next time it connects to the internet.

[0114] It should be noted that after the computer device updates the IP address corresponding to the candidate domain name based on the updated IP address, the cache time corresponding to the cached domain name will be recalculated from the time when the IP address corresponding to the cached domain name is updated, and the above steps S201 to S204 will be repeated until the candidate domain name and the IP address corresponding to the candidate domain name are deleted from the target cache.

[0115] In one specific implementation, referring to Figure 3, after obtaining the access frequency corresponding to the candidate domain name in step S203 above, the following steps S301 to S304 may be included, as follows:

[0116] Step S301: If the access frequency does not reach the frequency threshold, obtain the domain name type corresponding to the candidate domain name.

[0117] The domain name type refers to the type corresponding to the candidate domain name. The domain name type includes, but is not limited to, the first type, the second type, and the third type. Among them, the first type domain name is a known domain name that is preset in the computer device, such as some fixed URL applications of the company's self-developed applications. The second type domain name is a non-aging application domain name that is preset by the user according to the needs, such as video applications such as iQiyi and Aurora TV. The third type domain name is other domain names other than the first type and the second type domain names.

[0118] It should be noted that the first and second types of domain names are those that will not be aged out and deleted. Once the preset cache time is reached, the computer will automatically send a domain name resolution request to the domain name server and automatically update the IP address corresponding to that type of domain name in the target cache. The third type of domain name is those that will be aged out and deleted. After the preset cache time is reached, the computer will determine whether to delete that type of domain name from the target cache based on the frequency of access to that type of domain name.

[0119] Step S302: Determine whether the domain name type is the preset type.

[0120] The default type is a pre-set domain name type that will not be aged out or deleted. Determining whether the domain name type is the default type determines whether the domain name type is a domain name type that will not be aged out or deleted.

[0121] In one specific implementation, the preset type includes a first type and a second type, and the steps for determining whether the domain name type is a preset type specifically include:

[0122] (1) Determine whether the domain name type is the first type;

[0123] (2) If the domain name type is not the first type, obtain the domain name field corresponding to the candidate domain name and match the domain name field with the preset field;

[0124] (3) If the domain name field matches the preset field, determine the domain name type as the second type.

[0125] Specifically, the first type of domain name is a pre-defined known domain name in the computer device. Determining whether the domain name type is the first type means determining whether the candidate domain name is a pre-defined known domain name in the computer device. If the domain name type is determined to be the first type, then the domain name type is determined to be the pre-defined type. If the domain name type is determined not to be the first type, then the domain name field corresponding to the candidate domain name is further obtained, and the domain name field is matched with the pre-defined field. If the domain name field matches the pre-defined field, then the domain name type is determined to be the second type, that is, the domain name type is determined to be the pre-defined type. Otherwise, the domain name type is determined not to be the pre-defined type.

[0126] It should be noted that matching the domain name field with the preset field can mean that the domain name field is the same as the preset field, or that the domain name field is similar to the preset field. For example, if the domain name field is "tv.qq.com" and the preset field is "tv.qq", then the domain name field matches the preset field.

[0127] Step S303: If the domain name type is a preset type, send a first domain name resolution request for the candidate domain name to the domain name server.

[0128] Step S304: Obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the updated IP address.

[0129] If the domain name type is a preset type, it indicates that the candidate domain name is a domain name that will not be aged out and deleted. At this time, although the access frequency of the candidate domain name has not reached the preset frequency threshold, the computer device will still send a first domain name resolution request for the candidate domain name to the domain name server, and obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request. The IP address corresponding to the candidate domain name is then updated based on the updated IP address. Steps S303 and S304 are the same as those described in steps S203 and S204 above. For details, please refer to the discussion of steps S203 and S204 above. To avoid repetition, this application will not repeat them here.

[0130] In one specific implementation, referring to Figure 4, after determining whether the domain name type is a preset type in step S302 above, the following steps S401 to S402 can be included, as follows:

[0131] Step S401: If the domain name type is not the preset type, obtain the aging time corresponding to the candidate domain name and compare the cache time with the aging time.

[0132] Step S402: If the cache time reaches the aging time, delete the cached domain name and the corresponding IP address from the target cache.

[0133] To improve the caching performance of the target cache, if the access frequency of the candidate domain does not reach the preset frequency threshold, and the domain type of the candidate domain is not the preset type, that is, the candidate domain is a domain with low access frequency that can be aged out and deleted, then the aging time corresponding to the candidate domain is obtained, and the cache time is compared with the aging time. If the cache time reaches the aging time, the cache domain and the IP address corresponding to the cache domain are deleted from the target cache.

[0134] In this context, the aging time of multiple cached domains in the target cache can be set to the same or different. For example, the aging time of all cached domains in the target cache can be set to T1; or the aging time of cached domain A in the target cache can be set to T1, the aging time of cached domain B in the target cache can be set to T2, and the aging time of cached domain C in the target cache can be set to T3, where T1, T2, and T3 are not the same.

[0135] In one specific implementation, referring to Figure 5, the above domain name resolution method may further include the following steps S501 to S503, as detailed below:

[0136] Step S501: Obtain the network access request of the target application, which includes the target domain name;

[0137] Step S502: Based on the network access request, query whether there is a cached domain name in the target cache that matches the target domain name;

[0138] Step S503: If a cached domain name that matches the target domain name exists in the target cache, return the IP address corresponding to the cached domain name that matches the target domain name to the target application so that the target application can access the network based on the IP address corresponding to the cached domain name.

[0139] Computer devices typically include multiple applications, such as video applications, game applications, and communication applications. The target application is the application on the computer device that needs to access the network. The target domain name is the domain name address used by the target application to access the network. Different target applications correspond to different domain name addresses. For example, when the target application is iQiyi video, the target domain name is "tv.qq.com", and when the target application is Aurora TV, the target domain name is "tv.qq.com".

[0140] A network access request is a request constructed by a target application using a target domain name. When the target application needs to access the network, it can send a network access request carrying the target domain name to the operating system of the computer device. After receiving the network access request, the operating system of the computer device first checks whether there is a cached domain name matching the target domain name in the target cache. If there is a cached domain name matching the target domain name in the target cache, the computer device directly returns the IP address corresponding to the cached domain name matching the target domain name to the target application, so that the target application can access the network based on the IP address corresponding to the cached domain name. Since the IP address corresponding to the target application is directly resolved from the target cache, compared with the existing domain name resolution process, the target application can obtain the IP address for network access faster, thereby improving the application's network speed and avoiding the waste of system resources caused by repeated domain name resolution processes.

[0141] Furthermore, if no cached domain name matching the target domain name exists in the target cache, the computer device needs to send a domain name resolution request for the target domain name to the domain name server. Accordingly, referring to Figure 6, after querying whether a cached domain name matching the target domain name exists in the target cache based on the network access request in step S502 above, the following steps S601 to S602 may also be included, as follows:

[0142] Step S601: If there is no cached domain name matching the target domain name in the target cache, send a second domain name resolution request for the target domain name to the preset public domain name server;

[0143] Step S602: Obtain the IP address corresponding to the target domain name returned by the public domain name server based on the second domain name resolution request, and return the IP address corresponding to the target domain name to the target application so that the target application can access the network based on the IP address corresponding to the target domain name.

[0144] If no cached domain name matching the target domain name exists in the target cache, the computer device sends a second domain name resolution request for the target domain name to a preset public domain name server. After the public domain name server successfully resolves the IP address corresponding to the target domain name, it returns the IP address corresponding to the target domain name to the computer device, which then returns the IP address corresponding to the target domain name to the target application so that the target application can access the network based on the IP address corresponding to the target domain name. Compared with the servers allocated by the router currently used, the public domain name server can effectively avoid the problem of domain name hijacking and improve the accuracy of obtaining the IP address corresponding to the target domain name.

[0145] In cases where public domain name servers fail to resolve a target domain name, in one specific embodiment, if the public domain name server fails to resolve the target domain name, the computer device sends a second domain name resolution request for the target domain name to the domain name server assigned by the router, obtains the IP address corresponding to the target domain name returned by the domain name server assigned by the router based on the second domain name resolution request, and returns the IP address corresponding to the target domain name to the target application, so that the target application can access the network based on the IP address corresponding to the target domain name.

[0146] In one specific implementation, after obtaining the IP address corresponding to the target domain name returned by the public domain name server based on the second domain name resolution request in step S602 above, the method further includes:

[0147] Store the target domain name and its corresponding IP address in the target cache.

[0148] After storing the target domain name and its corresponding IP address in the target cache, the computer device can directly retrieve the IP address of the target domain name from the target cache the next time the target domain name needs to be resolved, thereby improving the resolution speed of the target domain name and thus improving the network speed of the application.

[0149] To better implement the domain name resolution method in this application embodiment, based on the domain name resolution method, this application embodiment also provides a domain name resolution device, as shown in Figure 7. The domain name resolution device 700 includes:

[0150] The information acquisition module 710 is used to acquire the cache time corresponding to the cached domain name in the target cache. The target cache includes the cached domain name and the IP address corresponding to the cached domain name.

[0151] The domain name determination module 720 is used to determine candidate domain names from cached domain names based on cache time. The candidate domain names are the domain names in the cached domain names whose cache time has reached the preset first time.

[0152] The domain name resolution module 730 is used to obtain the access frequency corresponding to the candidate domain name. If the access frequency reaches the preset frequency threshold, it sends the first domain name resolution request for the candidate domain name to the preset domain name server.

[0153] The first update module 740 is used to obtain the update IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the update IP address.

[0154] In this embodiment, candidate domains whose caching time reaches a preset first time are selected from the target cache. For candidate domains whose access frequency reaches a preset frequency threshold, a first domain name resolution request is sent to the domain name server. The IP address corresponding to the candidate domain is updated based on the updated IP address returned by the domain name server based on the first domain name resolution request. This allows for automatic updating of the IP addresses of frequently used domains in the target cache. Since the IP addresses of frequently used domains are always stored in the target cache, applications can directly obtain the IP address corresponding to the domain from the target cache when accessing the network, thereby improving the network speed of the application.

[0155] In some embodiments of this application, the domain name resolution device 700 further includes a second update module, which is specifically used for:

[0156] If the access frequency does not reach the frequency threshold, obtain the domain type corresponding to the candidate domain;

[0157] Determine if the domain name type is the default type;

[0158] If the domain name type is the preset type, send a first domain name resolution request for the candidate domain name to the domain name server;

[0159] Obtain the updated IP address corresponding to the candidate domain name returned by the domain name server based on the first domain name resolution request, and update the IP address corresponding to the candidate domain name based on the updated IP address.

[0160] In some embodiments of this application, the preset type includes a first type and a second type, and the second update module is further used for:

[0161] Determine if the domain name type is type 1;

[0162] If the domain name type is not the first type, obtain the domain name field corresponding to the candidate domain name and match the domain name field with the preset field;

[0163] If the domain name field matches the preset field, the domain name type is determined to be the second type.

[0164] In some embodiments of this application, the domain name update device 700 further includes a domain name aging module, which is specifically used for:

[0165] If the domain name type is not the preset type, obtain the aging time corresponding to the candidate domain name and compare the cache time with the aging time;

[0166] If the cache expires, the cached domain name and its corresponding IP address will be removed from the target cache.

[0167] In some embodiments of this application, the domain name resolution device 700 further includes a request processing module, which is specifically used for:

[0168] Obtain the network access requests of the target application, including the target domain name;

[0169] Based on the network access request, query whether there is a cached domain name in the target cache that matches the target domain name;

[0170] If a cached domain name matching the target domain name exists in the target cache, return the IP address corresponding to the cached domain name matching the target domain name to the target application so that the target application can access the network based on the IP address corresponding to the cached domain name.

[0171] In some embodiments of this application, the request processing module is further configured to:

[0172] If the target cache does not contain a cached domain name that matches the target domain name, a second domain name resolution request for the target domain name is sent to the preset public domain name server;

[0173] Obtain the IP address corresponding to the target domain name returned by the public domain name server based on the second domain name resolution request, and return the IP address corresponding to the target domain name to the target application so that the target application can access the network based on the IP address corresponding to the target domain name.

[0174] In some embodiments of this application, the domain name resolution device 700 further includes a domain name caching module, which is specifically used for:

[0175] Save the target domain name and its corresponding IP address to the target cache.
