Embodiment shall fall in the protection scope of this application.
Fig. 1 is a kind of system for the corresponding relationship for obtaining IP address and dns address (following letter disclosed in the embodiment of the present application
Referred to as system), comprising: service server, interface server and dns resolution server.Wherein, service server, interface service
Device and dns resolution server can be the entity device being separately provided, and also can integrate in an entity device.
Wherein, domain name, referred to as the first domain name are set for interface server in advance.Specifically, the first domain name can be work
The subdomain name of domain name.General domain name is set for dns resolution server in advance, general domain name is also the subdomain name of work domain name.Exist in advance
Name server (Name Serve, the NS) record of general domain name is set dns resolution server, i.e. DNS by domain name registration organ
Resolution server is the resolution server of general domain name.Optionally, IP address can also be set for dns resolution server in advance.
Fig. 2 is the process for the corresponding relationship that system shown in FIG. 1 obtains IP address and dns address, comprising the following steps:
S201: service server is in the case where detecting user's access, system trigger user's access interface server.
Specific trigger theory are as follows: if javascript script can be loaded in the page by page request.In wash with watercolours
After having contaminated the page, the order request that domain name is returned to interface server and interface server is initiated.It, can if requested by app
To realize to the above interface and return the order request of domain name in activitythread.
The specific implementation process of triggering mode, may refer to the prior art, which is not described herein again.
S202: interface server sends the IP for having user to user in the case where receiving the access request of user
The general domain name addresses of address.
The message used is communicated in the present embodiment, between user and system, is the same as those in the prior art, therefore, in user
When access interface server, interface server can obtain the IP address of user.
After getting the IP address of user, interface server is by the IP address of user and preset general domain name as previously described
Spliced, obtains the general domain name addresses (hereinafter referred to as splicing address) of the IP address with user.
S203: user splices address after receiving splicing address, to the dns server request analysis of user.
In the present embodiment, it is assumed that the parsing result information of general domain name addresses is not cached in the dns server of user, that
, the dns server of user can not locally obtain parsing result, because in domain name registration organ by the name server of general domain name
(Name Serve, NS) record is set as dns resolution server, so the dns server of user is by way of recursion resolution,
Parsing result, step such as S204 are finally obtained from the dns resolution server in system.
S204: the dns server of user splices address to dns resolution server request analysis, i.e. dns resolution server connects
Receive the analysis request of request analysis splicing address.
S205:DNS resolution server sends the IP address of general domain name to the dns server of user.
S206: the dns server of user sends the IP address of general domain name to user.
It should be noted that S205 and S206 is optional step, the purpose of execution is, it then follows existing user and network
The request of side and the entire flow of response, if do not occurred to one IP address of user feedback according to existing communication protocol
It reports an error, although the collection for corresponding relationship does not influence, the experience of possible user is bad, and it is noninductive also to cannot achieve user
In the case of collect corresponding relationship purpose.
S207:DNS resolution server obtains the IP address of the dns server of user and the corresponding of the IP address of user is closed
System.
It should be noted that be the same as those in the prior art as previously mentioned, communicate the message used between user and system,
Therefore, the general domain name addresses of the IP address of user is included the case where in the dns server request dns resolution server parsing of user
Under, dns resolution server can not only obtain the IP address of user, additionally it is possible to obtain the IP address of the dns server of user.
Because in the analysis request that the dns server of user issues dns resolution server, the IP address including user,
Also, in the case that the dns server request dns resolution server of user parses general domain name, dns resolution server can be obtained
The IP address of the dns server of user, so, system can establish the IP address and general domain name addresses of the dns server of user
In user IP address corresponding relationship.
Specifically, system dns resolution server can be obtained from the access log of dns resolution server including user
The IP address of the dns server of the user of the general domain name addresses and request analysis of the IP address domain name.Certainly, dns resolution service
Device can also be in the case where receiving analysis request, pair of the IP address of the IP address and dns server of real-time storage user
It should be related to.
It can be seen that access of the system trigger user for interface server from process shown in Fig. 2, to send out to user
The general domain name addresses of the IP address including user is sent, inquires splicing ground to dns resolution server to trigger the dns server of user
Location, and establish the dns address (i.e. the IP address of the dns server of user) of user and splice the IP address of the user in address
Corresponding relationship.It obtains the dns address and IP address of user together in a process, therefore, can be improved acquisition corresponding relationship
Efficiency.Also, the foundation of corresponding relationship is noninductive to user, will not influence the usage experience of user.
It is below exp001.com with the domain name of preset interface server, the general domain name of preset dns resolution server
Process shown in Fig. 2 is illustrated for IP address is A 12.12.12.12 for * .getdns.exp001.com.
(service server is not drawn into Fig. 3) as shown in Figure 3, the IP address (i.e. user's public network exit address) of user is
1.2.3.4, the IP address (i.e. the address of the dns server of user) of the DNS of user is 4.5.6.7.
In the case where user accesses mango TV APP (such as user terminal starts mango TV APP), the business service of APP
Device triggers user and sends request to interface server, and the IP address of user and general domain name addresses are spliced into 1-2- by interface server
3-4.getdns.exp001.com, and it is sent to user.User requests domain name mapping, the public affairs of user to the dns server of user
Iterative resolution request is issued dns resolution server by net dns server, and dns resolution server issues the IP address of general domain name
The IP address of general domain name is issued user by the public network dns server of the public network dns server of user, user.Module is obtained from DNS
The IP address of corresponding user and the IP address of public network DNS are obtained in the log of resolution server.
Based on upper example, system shown in FIG. 1 be can be set in APP (such as above-mentioned mango TV APP), be used for obtaining
The IP address at family and the corresponding relationship of DNS IP address.The corresponding relationship of acquisition is used in user's request content (such as in video
Hold) in the case where, content is provided a user using the content server nearest apart from user.
It should be noted that in the above description, it is assumed that do not cache the solution of general domain name in the public network dns server of user
Result information is analysed, so the public network dns server of user needs to request domain name mapping to DSN resolution server.In practice, such as
Fruit user accesses for the first time, then meets above-mentioned it is assumed that not caching the parsing result of general domain name in the public network dns server of i.e. user
Information.In the case, the opportunity for obtaining corresponding relationship is also complied with.If user is not to access for the first time, the public network DNS of user
Server has probably cached the parsing result information of general domain name, and in the case, the public network dns server of user will not ask
DSN resolution server is asked to carry out domain name mapping.But because the IP address and dns address for having had collected user are accessed for the first time
Corresponding relationship, so, the purpose for collecting corresponding relationship still can be used.
It is also possible that the public network dns server of user reaches preset duration (such as 24 hours) in caching parsing result information
Afterwards, cache contents are removed automatically, and in the case, the public network dns server of user needs to request domain name to DSN resolution server
Parsing, system can also be collected into the IP address of user and the corresponding relationship of dns address again.Therefore, even if the IP of user
Location or dns address have change, and system can also update corresponding relationship.
It should be noted that optional, in process described in Fig. 2, S201 and S202 be in the case where user's access, to
The user sends a kind of specific implementation of splicing address, and other way also can be used and realize that will splice address issues use
The function at family.Also, interface server is substantially the IP for having the function of sending splicing address and be able to access that with user
The module of address, resolution server, which is substantially, has the function of collecting corresponding relationship and the dns server with user can visit
The module for the IP address asked.
