Figure 1 shows that the structural representation of a kind of domain name analysis system in the embodiment of the present invention.This system comprises local parsing server 11 and detects server 12.
Local parsing server 11, for the domain name mapping request of receiving terminal, and obtain the address list corresponding with domain name, described address list is sent to and detects server 12, and receive the available address list that described detection server 12 returns, and available address list is sent to described terminal.
Detect server 12, for receiving the address list that described local parsing server 11 sends, confirming whether each address in described address list can be used, and returning available address list to described local parsing server 11.
In this embodiment, local parsing server changes domain name resolution process, and available address list is determined in inquiry, and returns available address list to terminal.Significantly improve the probability of the really available server address that domain name mapping returns.
The domain name mapping request of terminal is that A records analysis request, AAAA records analysis request or A6 records analysis request, the list of corresponding acquisition A recording address, the list of AAAA recording address or the list of A6 recording address, wherein, A records analysis request for representing that request returns the IPv4 address list of application server; The list of A recording address refers to the IPv4 address list of the application server that domain name mapping returns; AAAA records analysis request or A6 records analysis request for representing that request returns the IPv6 address list of application server; The list of AAAA recording address or the list of A6 recording address refer to the IPv6 address list of the application server that domain name mapping returns.AAAA record is different with A6 record format.
The corresponding relation of domain name and address preserved by name server, and name server is here authoritative domain name server, and the information of each authoritative domain name server all oneself is administered and maintained by each content service provider.The address of local parsing server 11 is exactly the domain name server address of end host configuration.Local parsing server 11 obtains the corresponding relation of domain name and address from name server, comprises IPv4 address and IPv6 address, and is kept in local cache.Local parsing server 11 is that the address list of domain name specifies ageing time thresholding To, if ageing time T is less than thresholding To, described local parsing server obtains address list from local cache, can promote the speed of response terminal like this.If ageing time T is greater than thresholding To or local cache does not preserve the address list corresponding with domain name, described local parsing server obtains the address list corresponding with domain name from name server.
Address list is sent to and detects server to confirm the availability of address by local parsing server, and namely whether these server address can provide application service.Local parsing server can inquire about the list of A recording address or the list of AAAA recording address respectively, also can complete the inquiry to A record and AAAA record in one query.From detecting the address list that returns of server as available server list, still represent with the list of A recording address and the list of AAAA recording address.A recording address list after inquiry and the list of AAAA recording address are local parsing server resolves the address list obtained subsets from authorization server.Both can be identical, also can be different.When both are different, deleted record detects the server address that server confirms to provide service.
The available address list that local parsing server 11 returns according to detection server 12 upgrades local cache.Such as, address list can be all sent to detection server by local parsing server 11, and receives the list of available addresses detecting server and return, and covers the address list in local cache, to upgrade local cache with this list of available addresses.Whether the A recording address list no matter returned and the list of AAAA recording address are empty, the list of original A recording address and the list of AAAA recording address are replaced in the A recording address list that local parsing server all uses inquiry to return and the list of AAAA recording address, and reset the A record of domain name and the ageing time T of AAAA record.A record and the AAAA record of domain name can use identical ageing time thresholding To, also can adopt different ageing time thresholding To for the list of A recording address and the list of AAAA recording address.Recording such as A recording address list and the list of AAAA recording address of domain name in local cache, can be the domain name of other any suffix, such as .org .com .com.cn etc.As long as associated dns name is resolved based on domain name resolution server (DNS).
Such as, A recording address list: IPv4_1, IPv4_2 ..., IPv4_m;
Such as, AAAA recording address list: IPv6, IPv6_2 ..., IPv6_n.
Here A recording address list, the list of AAAA recording address are all the domain name resolution process once completed, and detect server, confirm available application server address list through inquiry availability.
Local parsing server 11 returns A record or the list of AAAA recording address of available server domain name to terminal.When the list of terminal parses request A recording address, local parsing server returns available A recording address list; When the list of terminal parses request AAAA recording address, local parsing server returns available AAAA recording address list; When terminal asks A to record list and the list of AAAA recording address simultaneously, local parsing server returns available A record and the list of AAAA recording address.When the available A record of request type or the list of AAAA recording address be sky, local parsing server returns sky list.
Detect server can regularly detect, such as, interval T 0 detection time is set, arrive detection time, detect the address list that server reads each domain name in availability record storehouse, such as, A record and the list of AAAA recording address, detect the availability of all addresses in these address lists, and upgrade availability record storehouse.Detect the availability that server detects each server address, include but not limited to adopt Ping or initiate application request to server, such as set up TCP and connect, initiate the modes such as access request.Connecting when TCP can be set up, can think that server address can be used, when can not service be provided through detecting confirmation, thinking that this server address is unavailable.Address in the A record and the list of AAAA recording address of confirmation domain name can be used, and retains this address, and be labeled as available in address list; Through confirming disabled address, delete from A record and the list of AAAA recording address.After the availability of all addresses completing a domain name detects, with the A record after upgrading and the availability address list of AAAA recording address list update domain name.
Detect server and preserve available list of server addresses, and confirm whether each address the address list received from described local parsing server is kept in available list of server addresses, this address list can carry the list of A recording address and the list of AAAA recording address of domain name, regard the address of having preserved as available server address, that does not preserve regards disabled server address as, and available server address is left in available address list, return to described local parsing server.
Detect server and availability strategy can also be set, will preserve and belong to available address according to described availability strategy and leave in available address list, return to described local parsing server.Availability strategy can include but not limited to white list, blacklist etc.White list refers to through confirming available list of server addresses.Blacklist refers to through confirming disabled list of server addresses.When the address of the address list received from local parsing server is in white list, then the address list of the domain name returned comprises this address; When the address of the address list received from local parsing server is in blacklist, then the address list of the domain name returned must delete this address.
In prior art, owing to lacking the availability information of application server, disabled server address may be returned to terminal, cause terminal to experience the access time delay of tens seconds.The above embodiment of the present invention amendment domain name resolution process, inquires about the availability of each application server address list, and returns available list of server addresses to terminal before returns to field name analysis result.Avoid the IP address returning the application server lost efficacy to terminal, thus ensure that domain name resolution efficiency, improve response speed.
Figure 2 shows that the schematic flow sheet of a kind of domain name analytic method in the embodiment of the present invention.The method comprises:
In step 21, the domain name mapping request of local parsing server receiving terminal, and obtain the address list corresponding with domain name, described address list is sent to detection server.
