Fig. 1 schematically illustrates a block diagram of a domain name resolution system according to an exemplary embodiment of the present disclosure.
As shown in fig. 1, the domain name resolution system provided by the embodiment of the present disclosure may include an authoritative DNS server, a local DNS server, a target client, a CDN/ADN application server, and a source site network server.
In the embodiment of the disclosure, the target client may be any network terminal or network client such as a tablet computer, a notebook computer, an intelligent networked robot, and the like.
As shown in fig. 1, the local DNS server and the actual target client (which may also be referred to as a web client) are not located together and their geographic locations are not the same. Meanwhile, the local DNS servers configured for the target client are controlled by operators in various regions, and the change of the local DNS server cannot be timely updated to the authoritative DNS server of the CDN/ADN system, so that the target client may not be located by using the scheme in the prior art.
In the prior art, querying the geographical location of a network client by using the IP address of a local DNS server is a technical solution born in the traditional internet era based on a wired network. Under the conditions of prosperous development of mobile internet and internet of things and more mobile terminals and internet of things terminals, more and more accurate information can be transmitted to a DNS analysis system to judge the environment of a network client, so that an application server closest to the network client can be found more accurately.
With continued reference to FIG. 1, the workflow of the system may include the steps of:
s101: the target client sends a domain name resolution request to the local DNS server.
S102: and the local DNS server sends the domain name resolution request to an authoritative DNS server.
S103: and the authoritative DNS server responds to the domain name resolution request and returns a DNS resolution response to the local DNS server.
In practical cases, CDN/ADN application servers (or CDN/ADN service nodes) may be distributed around the world or nationwide, and an authoritative DNS server is needed to schedule and allocate a network client to the CDN/ADN application server closest to the network client.
In the embodiment of the present disclosure, the DNS resolution reply includes an IP address of a CDN/ADN application server closest to the target client, for example, it is assumed to be 2.2.2.2.
S104: and the local DNS server returns the DNS resolution response to the target client.
S105: and the target client sends a network request to a CDN/ADN application server with an IP address of 2.2.2.2 according to the DNS analysis response.
S106: and the CDN/ADN application server with the IP address of 2.2.2.2 sends the network request to a source station network server.
In the embodiment of the present disclosure, the source station network server is similar to an official network server of a certain company or a certain unit, if the XX network is provided with the source station network server in beijing, the original information source of the XX network is stored on the source station network server, but the network clients may come from all over the world, if the XX network acquires information from the source station network server, one aspect is that the access request is too large, another aspect is that the distance between the network client and the source station network server may be too far, and another aspect is that there may be a cross-network between the network client and the source station network server, for example, the source station network server is provided in a fixed network of link, but the network client is a mobile network, and then a CDN/ADN application server is also required to be provided in the mobile network in beijing.
S107: and the source station network server responds to the network request and returns a network response.
It should be noted that, if the network client sends a request for obtaining certain information to the CDN application server for the first time, the CDN application server needs to obtain the information from the source station network server, and then the information may be cached in the CDN application server, and when another network client requests the information again next time, the information may be directly read from the CDN application server, so that the user access speed may be increased.
S108: and the CDN/ADN application server with the IP address of 2.2.2.2 returns the network response to the target client.

As shown in fig. 3, a domain name resolution method provided by the embodiment of the present disclosure may include the following steps.
In step S310, a domain name resolution request sent by a target client is received, where the domain name resolution request includes geographic location information of the target client, operator information, and a target domain name to be resolved.
In the embodiment of the disclosure, the time of domain name resolution is very early, so that the environmental information of the target client can be collected earlier. For example, assuming that the target client is an intelligent networking robot, geographical location information and network operator information of the intelligent networking robot, etc. may be collected. The selection of an application server that is in the same carrier network as the network client may be facilitated by communicating the carrier information of the target client.
It should be noted that, in the domain name resolution request, in addition to the geographical location information and the operator information of the target client illustrated in the above embodiment, other information may be included, and the disclosure does not limit this.
In step S320, the domain name resolution request is resolved, and the geographic location information, the operator information, and the target domain name of the target client are obtained.
In step S330, geographic location information and operator information of a plurality of application servers are obtained according to the target domain name.

Fig. 4 schematically shows a flowchart of steps of a domain name resolution method in yet another exemplary embodiment of the present disclosure. The domain name resolution method provided by the embodiment of the present disclosure may be applied to a target client, but the present disclosure is not limited thereto.
As shown in fig. 4, a domain name resolution method provided by the embodiments of the present disclosure may include the following steps.
In step S410, a domain name resolution request is generated, where the domain name resolution request includes the geographic location information of the target client and a target domain name to be resolved.
In an exemplary embodiment, the geographical location information may include latitude information and longitude information.

In an exemplary embodiment, the domain name resolution request may further include operator information of the target client, so that the authoritative domain name server determines, according to the operator information of the target client and the operator information of the plurality of application servers, a target application server which is the same operator as the target client and closest to the target client.
In step S430, the IP address of the target application server returned by the authoritative domain name server is received.
The specific implementation of the domain name resolution method provided by the embodiment of the present disclosure may refer to the other embodiments described above.
Fig. 5 schematically illustrates a schematic diagram of a domain name resolution method in an exemplary embodiment of the present disclosure.
As shown in fig. 5, a domain name resolution method provided by the embodiments of the present disclosure may include the following steps.
In step S501, the target client sends a domain name resolution request to the local DNS server.
Specifically, as shown in fig. 5, deployed in a CDN or ADN network, a client ping local domain name server detects a domain name, which is assumed to be example.
In the embodiment of the present disclosure, before domain name resolution is performed on a target client (network terminal) having a navigation System such as a GPS (Global Positioning System) and a beidou navigation System, address position codes of the target client, including longitude and latitude information, may be converted into a format conforming to a DNS protocol and added to the front of a domain name to be resolved. In other embodiments, information encoding such as the operator encoding of the target client may also be appended to the domain name. This target client then initiates resolution of the combined domain name.
For example, get target client location: the latitude is 39.4361929993 and the longitude is 116.4111328125.
Then, since the latitude of the earth is-90 degrees to 90 degrees, in order to avoid the occurrence of negative numbers, 90 is added to the above latitude, which becomes 129.4361929993.
Next, the latitude to which 90 is added is multiplied by a first accuracy coefficient, which is assumed to be 10000, and 1294361.929993 is obtained.
Next, the latitude 1294361.929993 is reduced by a number after the decimal point to 1294361.
It should be noted that this first accuracy factor can be varied to see whether the accuracy requirement meets the requirement, and if so, all the decimal parts can be even removed, for example, the latitude is taken as 129 directly.
Similarly, (longitude +180) is multiplied by a second precision factor of 10000, and then the number following the latter decimal point is removed, and longitude becomes 2964111. The initial longitude is added by 180 because the longitude of the earth is-180 degrees to avoid negative numbers.
In addition, assume that the target client uses a connected network, and its network code is: 46001.
and finally, encoding the three information into a domain name to obtain: 1294361.2964111.46001.example.com, generates a domain name resolution request.
In the embodiment of the disclosure, the accuracy of the geographical position code is variable, so that the DNS cache is fully utilized to improve the domain name resolution efficiency.
In step S502, the local DNS server sends the domain name resolution request to the GSLB DNS server.
In the embodiment of the present disclosure, assuming that GSLB is an authoritative DNS server for example, the example domain name, all resolution requests for its sub-domain name are sent to GSLB.
It should be noted that, although only one local DNS server is shown in fig. 5, since the GSLB of fig. 5 is an authoritative DNS server for example, no matter which intermediate network devices are passed through, the pair 1294361.2964111.46001.
In step S503, the GSLB DNS server returns a DNS resolution response in response to the domain name resolution request.
In the embodiment of the present disclosure, the GSLB may extract and decode a target domain name to be resolved, geographical location information, and operator information of the target client from the resolved domain name, for example, the target domain name is example.
GSLB may query the IP address of the application server closest to the target client and in the same operator from the database storing the IP of the application server according to the parsed geographic location of the target client, which is assumed to be IP: 1.1.1.1. This IP address may then be returned to the target client as a DNS resolution reply.
In step S504, the local DNS server returns the DNS resolution response to the target client.
In step S505, the GSLB DNS server sends a record request to a requesting record server.
It should be noted that, in the embodiment of the present disclosure, the GSLB DNS server sends a record request to the request record server, and the request record server records the geographic location information and other information of each target client, for example, operator information. In other embodiments, however, the geographical location information and other information, such as operator information, of each target client may be directly recorded by the GSLB DNS server. In this case, the geographical location information and other information of each target client, for example, the operator information, may be recorded in the log database, but the present disclosure is not limited thereto.
In step S506, the request recording server sends a display request to the display terminal.
In the embodiment of the present disclosure, the display terminal may display the geographical location information of the target client extracted from the domain name to be resolved recorded in the log database and other information, such as operator information, through a map. In this way, each target client can be quickly located.
For example, if the target client is an intelligent networked robot, each robot can be quickly positioned, and if the robot has a problem, the robot can know where the robot has the problem. Wherein, to intelligent networking robot, the time delay of network is a great influence factor to the performance of robot, and this disclosed embodiment can make networking robot avoid traditional based on local DNS server carry out the inaccurate problem of domain name resolution through using the domain name resolution based on geographical position code. And faster connection to application servers, such as intelligent cloud servers, that are closer to the intelligent networked robot.
The domain name resolution method provided by the embodiment of the disclosure introduces a system for dynamic domain name resolution and network client information collection based on information such as geocoding, and the system relates to the modification of a network client and an authoritative DNS server, is completely compatible with a local domain name server and other intermediate network devices, conforms to the regulation of a DNS protocol, is simple in domain name generation, completes the search of a specific application server by the authoritative DNS server, does not influence the network client on the upgrade of an algorithm, and is more suitable for networking devices in the Internet of things.
Fig. 6 schematically illustrates a block diagram of a domain name resolution device according to an exemplary embodiment of the present disclosure. The domain name resolution device provided by the embodiment of the present disclosure may be applied to an authoritative domain name server, but the present disclosure is not limited thereto.
