location-1、ip-2,location-1、ip-3,location-1、ip-4,location-2、ip-5,location-2、
ip-6,location-2。
Usually, the IP address in the same area, different user is continuous.It therefore, can be to IP address and geography
The format of the mapping relations of location information is improved, and need not record the geographical location information of each IP one by one, but to each
One geographical location information carries out IP segment descriptions, i.e. an IP initial address and an IP termination address.
The format of improved IP address and the mapping relations of geographical location information can be：location,ip-begin,
Ip-end, such as
location-1,ip-begin-1,ip-end-1、location-2,ip-begin-2,ip-end-2、
location-3,ip-begin-3,ip-end-3。
Using such recording mode, when executing domain name mapping, secondary IP address is mapped to geographical location information
Process will be different.
Do not allow two record IP sections exist overlapping etc., include etc. relationships.The IP sections of i.e. different records should be mutual
It is independent.If from the point of view of gathering, each location corresponds to an IP set.It is recorded using the mode of segmentation, is because existing
In reality, the IP in this IP set is generally continuous, it is possible to which two IP address indicate a section.
One geographical location may include multiple sections.Because the target of IP information banks is that an IP is allowed to have unique geographical position
It sets, a geographical location includes multiple sections, can't destroy this target.This mode more meets reality scene.General one
The IP of cell is continuous section, but with the IP of another cell sections, then can be relatively far apart.
Meanwhile IP address can be applied to a variety of usage scenarios, such as public network with geographical location information mapping relations library, provide
General domain name resolution service；Or, corporate intranet；Or, the network structure between public network and Intranet.
It should be noted that the web results between public network and Intranet are determined by the characteristics of Broadcast and TV system.Broadcasting and TV row

It introduces, refers to Fig. 4, may include：
Step A41, the described intelligent name server is inquired in policy information base whether there is and the domain name to be resolved
And the domain name that matches of the corresponding geographical location information of IP address of the client and geographical location information.
If in the presence of A42 is thened follow the steps.
In the present embodiment, policy information base includes a plurality of different mapping relations, every mapping relations record be domain name,
The mapping relations of the IP address corresponding geographical location information and application server of client.
Step A42, by geographical location information phase corresponding with the domain name to be resolved and the IP address of the client
The corresponding application server of domain name and geographical location information matched, as the destination application server.
In the case of the IP address of known domain name and client corresponding geographical location information, it may be determined that answer accordingly
Use server.
It should be noted that the same domain name may have the case where multiple application servers provide service, in this way may be used
To prevent some application server from overloading, and cause service abnormal.
Wherein, it when the same domain name provides service by multiple application servers, can be determined in policy information base
The domain name and geography that multiple geographical location information corresponding with the domain name to be resolved and the IP address of the client match
The corresponding application server of location information, that is, multiple destination application servers.When there are multiple destination application servers, by institute
