In another schematic execution mode of the domain name inquiry method of DNS, the character string of inquiry of the domain name request comprises a reserved word, by reserved word interval between the domain name character of inquiry of the domain name request and Client location information.
In the schematic execution mode of the another kind of the domain name inquiry method of DNS, reserved word is in-addr.arpa.。
In another schematic execution mode of the domain name inquiry method of DNS, Client location information is the postcode of the IP address of DNS query client, the geographic name of the location of DNS query client or the location of DNS query client.
In another schematic execution mode of the domain name inquiry method of DNS, the inquiry request that DNS query client sends comprises the Client location information of DNS query client.
In another schematic execution mode of the domain name inquiry method of DNS, in the inquiry request that DNS recursion server is sent by DNS query client, read out the Client location information of DNS query client.
Embodiment
In this article, " schematically " expression " serves as example, example or explanation ", not should by being described to any diagram of " schematically " in this article, execution mode is interpreted as a kind of preferred or have more the technical scheme of advantage.
In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
Fig. 1 shows the structural representation of DNS query system.As shown in the figure, DNS query system comprises a DNS query client 10, DNS recursion server 20, DNS authority server 30 and a CDN server 40.When DNS query client 10 initiates an inquiry of the domain name, an inquiry of the domain name request is sent to DNS recursion server 20 by it.After DNS recursion server 20 receives the inquiry of the domain name request that DNS client sends, first this inquiry of the domain name request is compared with the caching record of DNS recursion server, if match hit caching record, then the IP address in content server corresponding to this inquiry of the domain name request or CDN server is directly returned to DNS query client 10 by DNS recursion server 20.If inquiry of the domain name request not with the caching record match hit of DNS recursion server, then inquiry of the domain name request is sent to DNS authority server 30 by DNS recursion server.DNS authority server 30, by the response of inquiry of the domain name request, returns to DNS query client 10 by DNS recursion server 20.In addition, the CDN server 40 in figure also can be replaced by content server or coexist with content server.
Below in conjunction with Fig. 1, the domain name inquiry method of DNS is described.
In step a, first obtained the positional information of DNS query client 10 by DNS recursion server 20.In a kind of exemplary embodiment of the domain name inquiry method of DNS, the positional information of DNS query client can be the postcode of the IP address of DNS query client, the geographic name of the location of DNS query client or the location of DNS query client, but be not limited to this, other guide can also be adopted to identify the positional information of DNS query client.
DNS recursion server 20 is obtained to the positional information of DNS query client 10, can be initiatively provided to DNS recursion server 20 by DNS query client 10, also can be win after reading the data message of the inquiry of the domain name request that DNS query client 10 sends by DNS recursion server 20.In a kind of exemplary embodiment of the domain name inquiry method of DNS, the inquiry of the domain name character string that DNS query client 10 generates comprises a reserved word, this reserved word can be used for identifying the positional information comprising DNS client in domain name inquiry request character string, and this reserved word is in-addr.arpa.IP address such as DNS query client 10 is 192.168.0.1, and the domain name needing inquiry is a.com, and inquiry of the domain name character string is 1.0.168.192.in-addr.arpa. a.com.But be not limited to this, other reserved word can be used as required to identify the positional information comprising DNS client in domain name inquiry request character string.In a kind of exemplary embodiment of the domain name inquiry method of DNS, the positional information of DNS query client is not comprised in the inquiry of the domain name request that DNS query client 10 sends, DNS recursion server 20 is after receiving inquiry of the domain name request, by the IP address reading DNS query client 10 in the data message of inquiry of the domain name request, and the inquiry of the domain name request that comprises the IP address of DNS query client 10 can be constructed.The inquiry of the domain name request of the IP address comprising DNS query client 10 is sent to DNS authority server 30 by DNS recursion server 20.
In stepb, the positional information comprised in inquiry of the domain name request extracts by DNS authority server 30.In a kind of exemplary embodiment of the domain name inquiry method of DNS, DNS authority server 30 can identify according to reserved word the address information comprised in inquiry of the domain name request.Be previously stored with the IP address of each CDN server 40 in the resource record of DNS authority server 30, and the domain name resources pointed by inquiry of the domain name request is stored in some CDN server 40.DNS authority server 30 can find all CDN server 40 storing domain name resources pointed by inquiry of the domain name request, and the IP address of DNS authority server 30 comparison DNS query client 10 and the IP address of these CDN server 40, thus find the CDN server 40 nearest with DNS query client 10 position, and the IP address of CDN server 40 is returned DNS recursion server 20 as the inquiry response of inquiry of the domain name request.
