Method in above-described embodiment can be executed by the terminal of operation application program, and the terminal for example can be hand
The various electronic equipments such as machine, tablet computer, game machine, PDA.
Below by taking network address is IP address as an example, the technical solution of the embodiment of the present invention is described in detail：
In an embodiment of the present invention, the mapping of domain name and IP address really simulates the parsing behavior of DNS request, leads to
It crosses and the mapping of domain name and IP address is carried out just across the resolving of dns server, to improve internetworking by terminal
Can, and hijacker is allowed to have no way of doing it.When obtaining the mapping relations of domain name and IP address, if terminal is by the location information of itself
(such as IP address, national code etc.) is added in the required parameter of mapped file, and server can be according to residing for client
Position issues the IP address nearest apart from its physical location, to reduce the delay of overall network request, realizes a degree of
Server Dynamical Deployment.Meanwhile terminal can safeguard the weight of the corresponding multiple IP address of domain name, when network switching to all
IP address carries out ping operations, to safeguard weight according to the corresponding first packet time, when the network request based on any IP address
When failure, the access weight of the IP address is reduced.
Wherein, the mapping relations of domain name and IP address can be stored by mapping table, specifically be illustrated in figure 4 domain name
402 with IP address 404 be one-to-many mapping relations, i.e. 1 domain name has corresponded to 5 IP address.
Specifically, mapping table includes domain name and corresponding IP address, and the program publication packet of APP carries initial mapping
Table.As shown in figure 5, when App starts, mapping table can be loaded onto in the memory of terminal.Furthermore, it is possible to be connect by cloud control
Mouthful, it checks whether there is new mapping table update and then downloads if there is update and verify decompression, while updating local mapping table.
As shown in figure 5, DNS pre-parsed can be carried out when APP startups or network switching, i.e., domain name is sent to DNS clothes
Business device, is parsed to obtain IP address by dns server.For example, can use C function CFHostSetClient and
CFHostStartInfoResolution realizes dns resolution function.If pre-parsed success, the IP obtained to pre-parsed
Location carries out IP assessments；If pre-parsed fails, do not handle, and wait for next startup opportunity or network switching.
Wherein, IP address is assessed and health examination mainly is carried out to IP address.It specifically, can be according to IP address
The corresponding first packet time calculates weight, and the first packet time is shorter, and weight is higher.For the IP of no network response or network error
Location can be labeled as unavailable.Wherein, when domain name and IP address are one-to-many relationships, health examination is preferably carried out；Work as domain name
When with IP address being one-to-one relationship, health examination can be carried out, health examination can not also be carried out.The result note of IP assessments
Record can select the maximum IP address of weight to initiate network request in IP weight tables in IP weight tables.
When initiating network request error based on the highest IP address of weight, by IP address addition blacklist, and according to
The next IP address of the sequential selection of weight from high to low initiates network request, when all IP address it is all unavailable (such as all by
Blacklist is added) when, directly by domain name access, i.e., domain name is sent to dns server, and returned according to dns server
IP address initiates network request.
It should be noted that：If the IP address that DNS pre-parsed obtains does not complete it in IP mapping tables, in IP assessments
Before, the IP address weight is optimal.At this point it is possible to initiate network request using the IP address, IP is avoided to assess time longer shadow
Ring the usage experience of user.
If the IP address that DNS pre-parsed obtains in IP mapping tables, which is not increased in mapping table, together
Carry out health examination.
Several situations of the optimal IP of return of the embodiment of the present invention are listed below, but the embodiment of the present invention is not limited to
This：
1, DNS pre-parsed does not complete, and when the IP address in IP mapping tables does not complete assessment, returns to domain name；
2, DNS pre-parsed does not complete, and when assessment is completed in the IP address in IP mapping tables, returns to IP address at random；
3, DNS pre-parsed is completed, and when the IP address in IP mapping tables does not complete assessment, returns to DNS pre-parsed results IP；
4, DNS pre-parsed is completed, and when assessment is completed in the IP address in IP mapping tables, optimal IP is returned according to weight；
5, DNS pre-parsed is completed, and the IP address in IP mapping tables is completed assessment, but the assessment knot of all IP address
When fruit is unavailable, domain name is returned.
If domain name in the mapping table, does not return to domain name first, dns resolution request then is initiated to dns server, and will solution
Analysis result is added in weight table.
