Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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 invention.
Referring to fig. 1, an embodiment of the present application discloses a method for searching an internet protocol address, which is applied to a client, and specifically includes the following steps:
s101, obtaining a domain name corresponding to a target page.
The target page refers to a page that needs to be browsed currently. Specifically, when a user wants to browse a target page, the user inputs a website of the target page into the browser and initiates a request for browsing the target page. Because the website of the target page contains the domain name of the target page, the client can further acquire the domain name corresponding to the target page through the website of the target page. The domain name is the name of a certain computer or a group of computers on the internet, which is composed of a string of names separated by dots, and is used for positioning and identifying the computer during data transmission. The domain name has a mapping relationship with an Internet Protocol (IP) address. One domain name corresponds to a plurality of IP addresses. In practical application, browsing a target page needs to be realized through an IP address corresponding to the target page. The domain name of the target page and the IP address of the target page have a mapping relationship, so that the domain name corresponding to the target page needs to be acquired to obtain the IP address corresponding to the domain name.
There are many ways to obtain the domain name corresponding to the target page, including but not limited to the content provided in the embodiments of the present application.
S102, screening an IP address recommendation list corresponding to the domain name in the configuration file, wherein the IP address recommendation list corresponding to the domain name comprises a plurality of IP addresses corresponding to the domain name.
If the IP address recommendation list is screened from the configuration file, step S103 is executed. And if the IP address recommendation list is not screened from the configuration file, finishing the search. Specifically, in the process of executing step S102, the client searches in the configuration file by using the domain name corresponding to the target page, and if the client has accessed the target page in the past time period, the client initiates a domain name resolution request to obtain an IP address list corresponding to the domain name. And further, the IP address list corresponding to the domain name may be processed to obtain an IP address recommendation list, and the IP address recommendation list is stored in the configuration file, so that when the client needs to access the target page again, the IP address recommendation list corresponding to the domain name can be screened in the configuration file by using the domain name corresponding to the target page. However, if the IP address recommendation list corresponding to the domain name is not screened in the configuration file, it indicates that the client may not access the target page in the past, or the list is deleted from the configuration file by the client due to the storage time being too long, and the like, so the IP address recommendation list corresponding to the domain name is not stored in the configuration file, and the screening of the configuration file may be ended.
The configuration file is a file which stores a plurality of IP address recommendation lists corresponding to domain names. The IP address recommendation list corresponding to the domain name is obtained by processing the IP address list corresponding to the domain name. The IP address recommendation list is different from an IP address list obtained by a client through a domain name resolution request in the prior art, and the IP address recommendation list stored in the configuration file can reflect the IP link quality of a plurality of IP addresses corresponding to the domain name. Through the IP address recommendation list, it can be seen which IP address has higher IP link quality and which IP address has lower IP link quality among the multiple IP addresses corresponding to the domain name, and then step S103 can be executed to select an IP address with high IP link quality. Optionally, the IP address recommendation list corresponding to the domain name may be a list that is sorted according to the level of the specific IP link quality parameter, or may be a list that includes: a list of IP addresses in the list of IP addresses to which the domain name corresponds, and a corresponding specific IP link quality parameter. That is, the IP address recommendation list includes, in addition to the IP addresses in the IP address list, specific IP link quality parameters corresponding to each IP address. Optionally, the IP address recommendation list may also be a list that sorts a plurality of IP addresses corresponding to the domain name according to the level of the IP link quality comprehensively reflected by the plurality of IP link quality parameters.
It should be noted that there are many IP link quality parameters, such as the packet loss rate of the IP address, the time for establishing a communication connection with the IP address, and the like. In the IP address recommendation list in the embodiment of the present application, one or more IP link quality parameters (i.e., specific IP link quality parameters) are selected as parameters for judging the link quality of an IP address. The IP link quality parameters may include: the packet loss rate of the IP address, and/or the time to establish a communication connection with the IP address. It should be noted that the IP link quality parameter is mainly used to reflect the quality of the IP link, and different IP link quality parameters are used to judge the quality of the IP link from different aspects. For example, the packet loss rate of an IP address is used to judge the quality of an IP link according to the degree of data loss, and the time for establishing a communication connection with the IP address is used to judge the quality of the IP link according to the speed of a communication response. If the data loss condition of the IP link is emphasized more in practical application, the packet loss rate of the IP address can be selected as the link quality parameter for judging the IP address in the IP address recommendation list, and if the communication is emphasized more smoothly, the time for establishing the communication connection with the IP address can be selected as the link quality parameter for judging the IP address in the IP address recommendation list. If the data loss condition of the IP link and the problem of whether the communication is smooth are considered at the same time, the packet loss rate of the IP address and the time for establishing the communication connection with the IP address can be selected as the link quality parameters for judging the IP address in the IP address recommendation list.
Optionally, referring to fig. 2, in an embodiment of the present application, a method for constructing an IP address recommendation list corresponding to a domain name in a configuration file includes:
s201, according to a preset update cycle, obtaining an IP address list corresponding to a domain name from a local cache or a domain name server, where the IP address list corresponding to the domain name includes: and a plurality of IP addresses corresponding to the domain names.
An updating cycle is preset, and the IP address recommendation list corresponding to the domain name of the target page is updated regularly by executing steps S201 to S204. In the process of accessing the target page for the first time, the client acquires the IP address list corresponding to the domain name, and further triggers and executes the process of periodically constructing the IP address recommendation list corresponding to the domain name in the configuration file shown in fig. 2.
Specifically, in the process of executing step S201, the client uses the domain name corresponding to the target page to provide a domain name resolution request corresponding to the target page according to a preset update period, and then obtains the IP address list corresponding to the domain name from the local cache or the domain name server. A list of corresponding IP addresses for the domain name, comprising: and a plurality of IP addresses corresponding to the domain name, wherein the link quality of each IP address in the IP address list corresponding to the domain name is unknown. Optionally, the process of acquiring the IP address list corresponding to the domain name from the local cache or the domain name server may be: after a domain name resolution request is provided by using a domain name, a client firstly checks whether an IP address list corresponding to the domain name exists in a local cache of a browser, and if the IP address list corresponding to the domain name can be found in the cache of the browser, resolution of the domain name is completed. If the IP address list corresponding to the domain name is not found in the local cache of the browser, the resolution of the domain name is finished, if the IP address list corresponding to the domain name is not found in the cache of the operating system, a domain name resolution request is sent to a domain name resolution server, and then the IP address list corresponding to the domain name returned by the domain name server is received, and the resolution of the domain name is finished. There are many ways to obtain the IP address list corresponding to the domain name, including but not limited to what is proposed in the embodiments of the present application.
Optionally, in a specific embodiment of the present application, when the step S201 acquires an IP address list corresponding to a domain name from a local cache or a domain name server, the method includes:
and calling a domain name resolution function by using the domain name corresponding to the target page, and obtaining an IP address list of the domain name from a local cache or a domain name server.
And calling a domain name resolution function by using a domain name corresponding to the target page to generate a domain name resolution request, and finding an IP address list of the domain name from a local cache or a domain name server after responding to the domain name resolution request.
It should be noted that the domain name used when the domain name resolution request is made may be resolved from the website of the target page when the target page is accessed for the first time, or may be already obtained from the domain name already stored in the configuration file. That is, after the target page is accessed for the first time, the IP address recommendation list corresponding to the domain name is constructed and stored in the configuration file through steps S201 to S204, and after the next update period, the client extracts the domain name corresponding to the target page from the configuration file, uses the domain name to obtain the IP address list corresponding to the domain name from the local cache or the domain name server (i.e., step S201 is executed), and then re-executes steps S202 to S204 to reconstruct the IP address recommendation list corresponding to the domain name.
Since the IP address in the IP address list corresponding to the domain name may change, the latest IP address list corresponding to the domain name is updated and acquired at regular time, so that it can be ensured that all the IP address recommendation lists corresponding to the domain names stored in the configuration file in the final step S204 are currently available IP addresses.
S202, using an Internet Packet detection tool (Packet Internet Groper, PING) to traverse each IP address in the IP address list corresponding to the domain name, so as to obtain an IP link quality parameter of each IP address.
PING is used to determine whether the client can successfully exchange (send and receive) data packets with the host corresponding to the IP address, and then, according to the returned information, the corresponding IP link quality parameters can be obtained, and whether the operation is normal or not, whether the network is unobstructed or not, etc. can be inferred.
Specifically, the PING sends a data packet to the host corresponding to the IP address for each IP address in the IP address list, and then calculates IP link quality parameters such as the packet loss rate of the IP address and the time for establishing a communication connection with the IP address according to parameter values such as the number of data packets and the time received from the host corresponding to the IP address. The PING command may select to acquire only one IP link quality parameter or select to acquire a plurality of IP link quality parameters, but the IP link quality parameters acquired in step S202 must include a specific IP link quality parameter, and the specific IP link quality parameter may be selected according to actual application requirements.
S203, according to the IP link quality reflected by the IP link quality parameters, the IP addresses in the IP address list are sorted to obtain an IP address recommendation list corresponding to the domain name.
Since the specific IP link quality parameter of each IP address in the IP address list is obtained in step S202, the IP addresses in the IP address list may be ranked from high to low, or from low to high, according to the IP link quality reflected by the IP link quality parameter, to obtain the IP address recommendation list corresponding to the domain name. If the IP addresses are arranged according to the high-to-low quality, the first IP address in the IP address recommendation list is the address which has the highest IP link quality and is most recommended to be used by the client, and if the IP addresses are arranged according to the low-to-high quality, the last IP address in the IP address recommendation list is the address which has the highest IP link quality and is most recommended to be used by the client.
Optionally, the IP addresses in the IP address list may be ranked from high link quality to low link quality or from low link quality to high link quality according to the high or low IP address quality reflected by one IP link quality parameter, or the IP addresses in the IP address list may be ranked from high link quality to low link quality or from low link quality to high link quality according to the link quality of the IP addresses comprehensively reflected by a plurality of IP link quality parameters. Alternatively, the IP addresses in the IP address list may be ranked from high link quality to low link quality according to the link quality of the IP addresses reflected by a specific IP link quality parameter, and if the specific IP link quality parameters are the same, the IP addresses may be ranked from high link quality to low link quality according to the link quality reflected by the IP link quality parameters other than the specific IP link quality parameter.
And S204, storing the IP address recommendation list corresponding to the domain name in a configuration file.
And storing the IP address recommendation list corresponding to the domain name obtained in step S203 in a configuration file. If the configuration file itself stores the IP address recommendation list corresponding to the domain name obtained in the previous update period, the IP address recommendation list corresponding to the currently obtained domain name may be replaced with the IP address recommendation list corresponding to the domain name obtained in the previous update period, and stored in the configuration file. Or, without replacement, adding the identifier of the update time of the list to the IP address recommendation list corresponding to the currently updated domain name, and storing the identifier in the configuration file.
Since the link quality parameters of the IP addresses are not constant, the embodiment shown in fig. 2 continuously updates the IP address recommendation list corresponding to the domain name, so that it can be ensured that the IP address recommendation list corresponding to the domain name stored in the configuration file is obtained by arranging according to the specific IP link quality parameters at the current stage, and the link quality of the IP address corresponding to the current domain name can be reflected.
Optionally, with reference to fig. 3, in an embodiment of the present application, after screening the recommended list of internet protocol IP addresses corresponding to the domain name in the configuration file, the method further includes:
s301, if the IP address recommendation list corresponding to the domain name is not screened from the configuration file, acquiring the IP address list of the domain name from a local cache or a domain name server, wherein the IP address list of the domain name comprises: and a plurality of IP addresses corresponding to the domain names.
If the IP address recommendation list corresponding to the domain name is not screened from the configuration file, in order to browse the target page, a domain name resolution request may be made by using the domain name corresponding to the target page, and the IP address list of the domain name is acquired from a local cache or a domain name server, so as to complete resolution of the domain name.
It should be noted that, if the IP address recommendation list corresponding to the domain name is not screened from the configuration file, the IP address recommendation list corresponding to the domain name may be still in the process of building and therefore not stored in the configuration file, or the IP address recommendation list corresponding to the domain name may not be stored in the configuration file because the client is a request for building a browsing target page for the first time, at this time, in the process of executing step S301, the process of building the IP address recommendation list corresponding to the domain name may be automatically triggered, and when the next user accesses the target page again, the IP address recommendation list corresponding to the domain name may be screened from the configuration file.
S302, an IP address is selected from the IP address list of the domain name as a target IP address.
Since the link quality of each IP address in the IP address list of the domain name acquired in step S301 is unknown, one IP address can be arbitrarily selected as a target IP address, and browsing a target page is implemented using the target IP address.
S103, if the IP address recommendation list is screened from the configuration file, selecting a target IP address from the IP address recommendation list, wherein the determination of the target IP address is associated with the IP link quality corresponding to the target IP address.
Specifically, the determination of the target IP address is associated with the IP link quality corresponding to the target IP address, and it can be understood that the target IP address is found from the IP address recommendation list from the direction that the IP link quality is good. Of course, whether the IP link quality of the IP address is good or not is generally reflected by the IP link quality parameter, and therefore, determining the target IP address according to the IP link quality mainly means determining the target IP address with high IP link quality according to the IP link quality parameter for reflecting the IP link quality.
Optionally, referring to fig. 4, in a specific embodiment of the present application, an implementation manner of selecting a target IP address from the IP address recommendation list in step S103 is executed, where the implementation manner includes:
s401, a plurality of alternative IP addresses are selected from the IP address recommendation list, wherein the IP link quality reflected by the IP link quality parameters of the alternative IP addresses is the IP address with high priority in the plurality of IP addresses included in the IP address recommendation list.
That is, among the plurality of IP addresses included in the IP address recommendation list, there are a plurality of IP addresses whose IP link quality is high priority, which are reflected by the IP link quality parameter, and all the IP addresses whose IP link quality parameters belong to high priority in the IP address recommendation list may be used as the candidate IP addresses.
Alternatively, the alternative IP address may be an IP link quality reflected by a specific IP link quality parameter, and a high-priority IP address in the IP address recommendation list is recommended. Or the IP link quality parameter comprehensively reflected by a plurality of IP link quality parameters is an IP address with high priority in the IP address recommendation list.
Optionally, in a specific embodiment of the present application, an implementation manner of executing step S401 may be:
and selecting n alternative IP addresses from the IP address recommendation list according to the specific IP link quality parameters. The IP link quality reflected by the specific IP link quality parameter of the alternative IP address belongs to one of the optimal n IP addresses in the IP address recommendation list, wherein n is a positive integer greater than one.
Namely, the n IP addresses with the optimal specific IP link quality parameters in the IP address recommendation list are all used as alternative IP addresses. For example, if n is 2 and the specific IP link quality parameter is the packet loss rate, the alternative IP address is one of the 2 IP addresses with the lowest packet loss rate in the IP address recommendation list. If the specific IP link quality parameter is the time for establishing the communication connection with the IP address, the alternative IP address is one of the 2 IP addresses with the shortest time for establishing the communication connection in the IP address recommendation list. And if the specific IP link quality parameter is the packet loss rate and the IP address recommendation list is a list in which the IP addresses are arranged according to the packet loss rate from low to high, directly selecting the previous 2 IP addresses as the alternative IP addresses.
Optionally, if the alternative IP address is an IP link quality reflected by one specific IP link quality parameter and is an IP address with a high priority in the IP address recommendation list, the alternative IP address may also be an IP address whose specific IP link quality parameter meets the high priority condition among a plurality of IP addresses included in the IP address recommendation list. If the specific IP link quality parameter of the IP address meets the high-priority condition, the IP link quality of the IP address is considered to be high-priority and can be used as a standby IP address. And one or more IP addresses with specific IP link quality parameters meeting the high-priority condition in the IP address recommendation list are selected, if only one IP address meeting the high-priority condition exists, the IP address is directly used as the target IP address, and if a plurality of IP addresses meeting the high-priority condition exist, the IP addresses are all used as alternative IP addresses. For example, if the specific IP link quality parameter is the packet loss rate, the high priority condition is that the packet loss rate is lower than the packet loss threshold, and there are multiple IP addresses in the IP address recommendation list whose packet loss rate is lower than the packet loss threshold, then all the multiple IP addresses satisfying that the packet loss rate is lower than the packet loss threshold are taken as the alternative IP addresses. For another example, if the specific IP link quality parameter is the time for establishing the communication connection, the high priority condition is that the time for establishing the communication connection is less than the time threshold, and there are a plurality of IP addresses in the IP address recommendation list, where the time for establishing the communication connection is less than the time threshold, then all the IP addresses satisfying that the time for establishing the communication connection is less than the time threshold are taken as the candidate IP addresses. And if the specific IP link quality parameter is the packet loss rate and the IP address recommendation list is a list in which the IP addresses are arranged from low to high according to the packet loss rate, checking whether the packet loss rate meets a high-priority condition from the first IP address, and if the nth IP address does not meet the high-priority condition, taking the 1 st to the nth-1 st as alternative IP addresses.
Optionally, if the specific IP link quality parameters of all the IP addresses in the IP address recommendation list do not satisfy the high priority condition, the IP address with the optimal specific IP link quality parameters may be directly selected as the target IP address without selecting a standby IP address. Wherein, the specific IP link quality parameter being optimal means that the IP link quality reflected by the specific IP link quality parameter is optimal.
Optionally, if the alternative IP address is an IP link quality parameter comprehensively reflected by the multiple IP link quality parameters and is an IP address with a high priority in the IP address recommendation list, the alternative IP address may be an IP address whose multiple IP link quality parameters all satisfy a high priority condition among the multiple IP addresses included in the IP address recommendation list. For example, the high priority condition may be that the packet loss rate needs to be lower than a packet loss threshold, and the time for establishing the communication connection is less than a time threshold. And if there are a plurality of IP addresses meeting the high-priority condition in the IP address recommendation list, all the IP addresses meeting the high-priority condition are taken as alternative IP addresses.
S402, selecting a target IP address from the plurality of candidate IP addresses.
The IP link quality reflected by the IP link quality parameters of the alternative IP addresses is high-priority in the IP addresses included in the IP address recommendation list, so that the IP link quality of the alternative IP addresses can be considered to be high, network communication is not smooth, the situation of loss of acquired page data is small, and the internet surfing experience of a user can be guaranteed.
Therefore, one candidate IP address can be arbitrarily selected from the plurality of candidate IP addresses as the destination IP address. And the target IP address is an IP address finally used for realizing page browsing.
Alternatively, the candidate IP address with the best IP link quality may be selected from the multiple candidate IP addresses as the target IP address. The target IP address can be a candidate IP address with the best IP link quality reflected by one IP link quality parameter, or can be a candidate IP address with the best IP link quality reflected by a plurality of IP link quality parameters in a comprehensive manner.
Optionally, in an embodiment of the present application, if, when step S401 is executed, n candidate IP addresses are selected from the IP address recommendation list according to the specific IP link quality parameter, then when step S402 is executed, the method may include:
and selecting a target IP address from the n alternative IP addresses according to the IP link quality parameters except the specific IP link quality parameter.
The IP link quality reflected by the IP link quality parameters of the target IP address except the specific IP link quality parameters belongs to the optimal one of the n alternative IP addresses. For example, after n IP addresses with the lowest packet loss rate are selected from the IP address recommendation list and used as candidate IP addresses, the IP address with the shortest communication connection time may be selected from the n candidate IP addresses and used as the target IP address. The selected target IP address can be regarded as the IP link quality that is comprehensively reflected by the packet loss rate and the communication connection time to be optimal.
Alternatively, if n candidate IP addresses are selected from the IP address recommendation list according to the specific IP link quality parameter when step S401 is executed, then the target IP address with the optimal specific IP link quality parameter in the n candidate IP addresses may be directly used when step S401 is executed. The selected target IP address may be regarded as the IP address with the best IP link quality reflected by a specific IP link quality parameter.
Optionally, if an error occurs in the process of obtaining the target page through the target IP address after the step S402 is executed, the target IP address may be replaced, that is, another alternative IP address except the original target IP address is selected from the alternative IP addresses in the step S401 to serve as a new target IP address, and the new target IP address is reused to obtain the target page. Since a plurality of candidate IP addresses are selected in step S401, and all of the plurality of candidate IP addresses are IP addresses with high IP link quality, if the target IP address selected from the plurality of candidate IP addresses cannot implement target page browsing, other candidate IP addresses can also ensure that conditions such as network communication is not smooth and the acquired page data is lost during the target page browsing process.
