First below to this specification relates to technical term simply introduced.
Domain name system (DNS) is a kernel service of internet, and it, which is used as, mutually to map domain name and IP address A distributed data base, user can be made more easily to access internet, remember directly to be read by machine without spending The IP number strings taken.
Although the node on internet can use IP address unique identification, and can be accessed by IP address, Even the binary IP address of 32 to be write as to the tens form of 4 0~255, user's memory, therefore domain name are also not easy to (Domian Name) is arisen at the historic moment, and an IP address can be associated with one group of significant character up by domain name.User accesses one When individual website, the IP address of the website can be both inputted, its domain name, for data access, Liang Zheshi can also be inputted Of equal value.
Domain name analysis system in present specification by DNS authority server, DNS recursion servers and groups of clients into, By network connection between DNS authority server and DNS recursion servers, pass through net between DNS recursion servers and client Network connects.
In the course of the work, sending a DNS to DNS recursion servers from client first please for above-mentioned domain name analysis system Ask, it will be understood that the DNS request shows as message form, the heading for the DNS request that client is sent during transmission In source IP address be client IP address；, can be by the message of DNS request after DNS recursion servers receive the DNS request After source IP address in head is replaced, then DNS request is transmitted to DNS authority server.
Specifically, the source IP address in the heading of DNS request can be replaced with DNS recursion services by DNS recursion servers The IP address of device itself, or, if DNS recursion servers there are multiple outlets, and each export with being configured with different IP Location, then from which outlet forwarding, DNS recursion servers will replace the source IP address in the heading of DNS request DNS request It is changed to the IP address of the outlet.
Further, since the presence of NAT (Network Address Translation, network address translation) technology, DNS The source IP address included in the heading for the DNS request that authoritative server receives is probably the IP address after NAT is changed.
As seen from the above, the source IP address 1 included in the heading for the DNS request that DNS authority server receives is not It must be the real IP address of DNS recursion servers, less be the IP address of client, but DNS authority server receives DNS request heading in the source IP address 1 that includes have certain corresponding relation with DNS recursion servers.
DNS authority server can be inquired about on domain after the DNS request is received based on the domain name carried in DNS request The mapping library of name and IP address, IP address corresponding to the domain name is then obtained, and the IP address is returned through DNS recursion servers To client.
But it is above-mentioned on the mapping library of domain name and IP address in, when the domain name in the DNS request is corresponding with multiple IP Address, and when content server corresponding to these IP address or CDN server are in different geographical position, DNS authority clothes Business device can be based on source IP address 1, inquire about existing IP address geolocation mapping database, obtain to should source IP address 1 Geographical position 1, and obtain simultaneously multiple IP address corresponding to the domain name in the DNS request distinguish corresponding to multiple geographical positions Put, then in multiple geographical position from there, it is determined that with geographical position 1 at a distance of nearest geographical position 2, finally by geographical position Put result of the IP address corresponding to 2 as domain name mapping.
It should be noted that in the IP address geolocation mapping database of prior art, corresponding to each IP address Geographical position characterize be：The geographical position being configured with where the equipment of the IP address, for example, the IP address geolocation mapping In database, IP address 36.7.72.139 and geographical position Hefei City, Anhui Province corresponding relation are stored with, it will be understood that match somebody with somebody The main frame for being equipped with the IP address is located at Hefei City, Anhui Province；And IP address geolocation mapping database of the prior art, Update cycle is very long.
