Request.
In the device of domain name mapping, there are preset parsing strategy sets, each in the preset parsing strategy set
Item parsing strategy all includes the corresponding relationship of IP address and server set, characterizes the resolution server in server set,
It is capable of handling the domain name mapping that purpose IP address is the IP address to request, can handle and be sent to DNS belonging to the IP address
The domain name mapping of server is requested.Wherein, the server set of each parsing strategy includes multiple resolution servers.It names
Example explanation.
The preset parsing strategy set of table 1.
Table 1 shows preset parsing strategy set, and parsing strategy policy-1 includes 101.56.2.88 and analysis service
The corresponding relationship of device server-1, server-2 and server-3 indicate, including purpose IP address 101.56.2.88's
Domain name mapping request can carry out domain name mapping processing by resolution server server-1, server-2 and server-3,
It is also shown that it is sent to the domain name mapping request for the dns server that IP address is 101.56.2.88, it can be by resolution server
Server-1, server-2 and server-3 carry out domain name mapping processing.
Parsing strategy policy-2 includes 170.5.215.6 and resolution server server-2, server-3, and
The corresponding relationship of server-4 indicates that the domain name mapping request including purpose IP address 170.5.215.6 can be by parsing
Server -2, server-3 and server-4 carry out domain name mapping processing, it is also shown that being sent to IP address and being
170.5.215.6 the domain name mapping of dns server is requested, can by resolution server server-2, server-3, and
Server-4 carries out domain name mapping processing.

It is understood that above-mentioned table 1 is only used in order to which preset parsing strategy set is illustrated, and not only
It is limited to preset parsing strategy set shown in table 1, can be specifically arranged according to actual needs.
When receiving domain name mapping request, the purpose IP address in domain name mapping request is obtained, from preset parsing plan
Slightly in set, the corresponding parsing strategy of purpose IP address is searched, parses strategy as target.
Wherein, if in preset parsing strategy set, the corresponding relationship including purpose IP address and parsing strategy then can
According to domain name mapping request in purpose IP address, its corresponding parsing strategy is directly searched from preset parsing strategy set
Strategy is parsed as target.
Wherein, if in preset parsing strategy set, the cryptographic Hash including purpose IP address is closed with the corresponding of parsing strategy
System, then calculate the cryptographic Hash of the purpose IP address in domain name analysis request, search the Hash from preset parsing strategy set
It is worth corresponding parsing strategy as target parsing strategy.
It is, of course, also possible to search target parsing strategy corresponding with purpose IP address, here using other implementations
No longer repeat one by one.
103: selecting a resolution server as destination server from the server set of target parsing strategy, by domain
Name analysis request is sent to the destination server and carries out domain name mapping.
After finding the corresponding target parsing strategy of purpose IP address, then it can use the server of target parsing strategy
Resolution server in set requests the domain name mapping to carry out domain name mapping.The server set packet of target parsing strategy
Include multiple resolution servers, need from multiple resolution server select a resolution server to the domain name mapping request into
Row domain name mapping.
As shown in the above, technical solution provided by the present application can will be sent to the multiple of the same dns server
Domain name mapping request is assigned to multiple and different resolution servers and carries out domain name mapping, effectively reduces the negative of the dns server
Lotus, avoid dns server receive in a short time a large amount of domain name mapping request when, can not normal response, guarantee user just
Website is asked in frequentation.
In one example, described one resolution server of selection from the server set of target parsing strategy is made
Include: for destination server
From the target parsing strategy server set in, selected by the way of poll a resolution server as
Destination server.
After being determined that the corresponding target parsing of target ip address is tactful in domain name mapping request, need to parse plan from the target
Select a resolution server as destination server in server set slightly.Wherein it is possible to from the clothes of target parsing strategy
It arbitrarily selects a resolution server as destination server in business device set, which is requested to carry out domain name mapping.
In one example, the sequencing that domain name mapping request is handled in server set can be preset, according to
The preset sequencing carries out domain name mapping to the domain name mapping request received one by one by the way of poll.
For example: in preset parsing strategy set shown in table 1, if parsing strategy policy-2 is that target parses plan
Slightly, it presets according to server-2, server-3, the sequence of server-4 carries out domain name mapping.Then receive first mesh
When marking domain name mapping request of the IP address corresponding to parsing strategy policy-2, it is assigned to server-2 and carries out domain name mapping；Then
Receive second target IP address correspond to parsing strategy policy-2 domain name mapping request when, be assigned to server-3 into
Row domain name mapping；When then receiving domain name mapping request of the third target ip address corresponding to parsing strategy policy-2, point
It sends to server-4 and carries out domain name mapping；Then receive the domain name that the 4th target ip address corresponds to parsing strategy policy-2
When analysis request, return is assigned to server-2 and carries out domain name mapping, and so on, it is ensured that each parsing in server set
It is balanced as far as possible that server carries out domain name mapping.
In another example, described to select a resolution server from the server set of target parsing strategy
Include: as destination server
From the server set of target parsing strategy, select the smallest resolution server of bandwidth availability ratio as mesh
Mark server.
The bandwidth availability ratio of one resolution server refers to bandwidth used in the current resolution server, with the solution
The ratio for the maximum bandwidth that analysis server is capable of providing.The bandwidth availability ratio of resolution server is higher, the load of the resolution server
It is bigger.
Therefore, in the server set for searching target parsing strategy, the smallest resolution server of bandwidth availability ratio, i.e., by mesh
In the server set of mark parsing strategy, the smallest resolution server of load can be reduced more effectively as destination server
The load of the big resolution server of load, the load of each resolution server in equalization server set.
In another example, in the server set of each parsing strategy, including the corresponding IP of the parsing strategy
Dns server belonging to address.
It is understood that in presetting parsing strategy set, server set in every parsing strategy can be with
It can not also include purpose IP address in the parsing strategy including dns server belonging to purpose IP address in the parsing strategy
Affiliated dns server.Regardless of whether including dns server belonging to purpose IP address in parsing strategy, can use upper
State the mode of any one selection target server.
Wherein, in the server set in every parsing strategy, including belonging to purpose IP address in the parsing strategy
It is described to select a resolution server to take as target from the server set of the target parsing strategy when dns server
Business device include:
Whether the bandwidth availability ratio for detecting dns server belonging to the destination IP address is more than preset threshold；
When the bandwidth availability ratio of the dns server belonging to the destination IP address is more than preset threshold, from the target
In the server set for parsing strategy, select a resolution server in addition to the dns server as destination server,
Polling mode selection target server is used, or selects the smallest resolution server of bandwidth availability ratio as destination service
Device.
Can first detect dns server belonging to the target ip address of domain name analysis request bandwidth availability ratio whether be more than
The Target IP can be used if not, indicating the load of dns server belonging to the target ip address and little in preset threshold
Dns server belonging to address requests the domain name mapping to carry out domain name mapping；If so, indicating belonging to the target ip address
Dns server load is very big, at this point, from target parsing strategy server set in, select one in addition to the dns server with
Outer resolution server is as destination server.
It is understood that when selecting a resolution server other than the dns server as destination server,
Can also in the way of any one above-mentioned selection target server, using polling mode selection target server, or
Select the smallest resolution server of bandwidth availability ratio as destination server.
In another example, the method also includes:
Receive the domain name mapping result to domain name analysis request that the destination server returns；
Domain name resolution response is sent to the terminal device, domain name resolution response includes the destination IP address and institute
State domain name mapping result.
After having selected destination server, the received domain name mapping request of institute is sent to destination service by the device of domain name mapping
Device requests the domain name mapping by destination server to carry out domain name mapping, obtains domain name mapping as a result, being the website to be accessed
IP address.
Destination server translates domain names into the device that result is back to the domain name mapping, and the device of the domain name mapping is to terminal
Equipment sends domain name resolution response, and source IP address is the purpose IP address in domain name mapping request in domain name mapping response, i.e.,
The IP address of dns server.After terminal device receives domain name mapping response, the domain name in domain name mapping response can be obtained
Parsing result.Wherein, due to the domain name mapping response in source IP address be dns server IP address, which sets
It is that domain name mapping is carried out by non-dns server for domain name mapping request can not be perceived.
After terminal device obtains domain name mapping result, net is accessed according to the IP address of the website in the domain name mapping result
It stands.
In domain name mapping scheme provided by the present application, translate domain names into request be assigned to multiple and different resolution servers into
Row domain name mapping reduces the load of dns server, guarantees that user normally accesses website.
