In step S120, to determine in the buffer memory storehouse of dns server or DNS database without the domain name mapping result matched with the domain name of request analysis, also may exist in the buffer memory storehouse of dns server or DNS database simultaneously and have the domain name mapping result matched with the domain name of request analysis.Dns server is that keyword is to buffer memory storehouse or DNS data base querying domain name mapping result according to the domain name of request analysis.
That is, to have in the buffer memory storehouse determining dns server or DNS database or in process without domain name mapping result, in fact comprise following two steps, first dns server inquires about the domain name mapping result whether having and match with the domain name of request analysis in buffer memory storehouse, if the result do not matched with the domain name of request analysis in the buffer memory storehouse of dns server, then inquire about the domain name mapping result whether having and match from the DNS database of itself.If have the domain name mapping result matched with the domain name of request analysis in the buffer memory storehouse of dns server or DNS database, then directly enter step S150, in domain name mapping result, choose domain name mapping result return to browser of mobile terminal.
Wherein, whether have in the process of the domain name mapping result matched with the domain name of request analysis in the buffer memory storehouse or DNS data stock of inquiry dns server, the data format of domain name mapping result in buffer memory storehouse or DNS database is: domain name _ result+IP_ result+life span ttl_ result+location _ result+place operator.
Such as, the domain name of the browser of mobile terminal request analysis in a Unicom Guangdong Branch net is had to be: www.sina.com.cn, the data format of the domain name mapping result so matched with this domain name in buffer memory storehouse is: www.sina.com.cn_218.30.21.65_600_ Guangdong _ UNICOM.Domain name mapping result is returned to browser of mobile terminal by the data format preset by dns server, and the form preset i.e. the data format of domain name mapping result in buffer memory storehouse, therefore, the domain name www.sina.com.cn of the browser of mobile terminal request analysis in Unicom Guangdong Branch net returns results as www.sina.com.cn_218.30.21.65_600_ Guangdong _ UNICOM.
In a particular embodiment of the present invention, if dns server does not inquire the domain name mapping result matched with the domain name of request analysis in buffer memory storehouse or DNS database, then form Bind caching server group by multiple Bind caching server, and each Bind caching server obtains domain name mapping result by the circuit of an operator of this region to public network dns server.
That is, if do not inquire the domain name mapping result matched in the buffer memory storehouse or DNS database of dns server itself, then by multiple buffer memory DNS example, namely on a dns server, run multiple identical program, initiate inquiry to public network DNS.Wherein, dns server initiates standard DNS queries by the self-built Bind caching server of many groups in the middle of multiple region simultaneously, and the self-built Bind caching server of in the middle of multiple region many groups is to the circuit of the different operators by this region to public network nslookup analysis result.
In embodiments of the invention, browser of mobile terminal may send multiple domain name mapping request simultaneously, browser of mobile terminal also may send the analysis request of some domain names from multiple dimension simultaneously, such as: browser of mobile terminal sends 10 domain name mapping requests by the network of movement simultaneously, send request from 3 dimensions simultaneously, here 3 dimensions refer to that user habit, navigation page are placed, historical record three aspects, and therefore dns server receives 30 domain name mapping requests simultaneously.Simultaneously due to dns server should be self-built by many groups in the middle of multiple region Bind caching server initiation standard DNS queries, inquired about to public network to the circuit of the different operators by this region by the Bind caching server that many groups in the middle of multiple region are self-built again, the domain name mapping result that so dns server likely obtains is made up of multiple analysis results of multiple domain name.
That is dns server can receive the multiple analysis results under a domain name simultaneously, and the domain name mapping result obtained when there is requested twice of same domain name, or the identical analysis result that same domain name obtains on different circuit.Therefore, before domain name mapping result is returned to browser of mobile terminal by dns server, also comprise that to carry out domain name to domain name mapping result be the process of uniquely identified duplicate removal, namely ensure the analysis result not have repetition in the analysis result of a domain name.In a specific embodiment of the present invention, by web interface, the analysis result repeated is removed.Wherein, this web interface is write by nginxscrIPt technology, and interface specification is:
Request:domain1_ evades IP1; Domain1_IP2.Wherein evade IP when referring to that requirement returns IP, do not return identical IP, only return other result.
After duplicate removal, by analysis result merge, namely same domain name from different route or by the analysis result that different approaches obtains carry out mergings classification.Wherein, choosing domain name mapping result at dns server returns in the process of browser of mobile terminal, the operator that the availability (namely whether domain name mapping often makes mistakes) of the region that browser of mobile terminal is originated according to domain name mapping result, domain name mapping result and domain name mapping result are originated, determine domain name mapping result, and this result is returned to browser of mobile terminal.

The multiple domain name mapping results inquired are sent to dns server by Bind caching server group, in the buffer memory storehouse that the domain name mapping result received is stored in dns server by dns server or DNS database.Wherein, according to inquiry with operator's classification, dns server by region matching process by the domain name mapping result classified and stored that receives in the buffer memory storehouse or DNS database of dns server.
In specific embodiment of the invention, region matching process comprises, the IP of browser of mobile terminal is mated with the region table of comparisons and the IMEI of browser of mobile terminal is mated with the operator table of comparisons, with region and operator belonging to the domain name obtaining browser of mobile terminal request analysis.
Because the website of target domain name is in order to realize load balancing, usually multiple IP can be adopted to do DNS poll, therefore by route inquiry in a region to IP corresponding to the domain name of this request analysis also may have multiple, namely the corresponding multiple domain name mapping result of domain name is after receiving and returning results, first dns server gathers the result that returned by self-built Bind server group and the domain name mapping result by recording in own cache storehouse and DNS storehouse, then duplicate removal process can be carried out to result, namely the result removing the identical IP in analysis result under same domain name is merged into a result, the region that further dns server is originated by domain name mapping result, the operator that the availability (namely whether domain name mapping often makes mistakes) of domain name mapping result and domain name mapping result are originated, determine domain name mapping result, and this result is returned to browser of mobile terminal, i.e. step S280.
By the inquiry of Bind caching server group, just can realize the inquiry of the many records of single domain name, under namely can inquiring about a domain name simultaneously, the analysis result on different circuit, even if like this one of them circuit query less than, also can by All other routes inquiry obtain analysis result.
