Embodiment
Exemplary embodiment of the present disclosure is described below with reference to accompanying drawings in more detail.Although shown exemplary embodiment of the present disclosure in accompanying drawing, yet should be appreciated that and can realize the disclosure and the embodiment that should do not set forth limits here with various forms.On the contrary, it is in order more thoroughly to understand the disclosure that these embodiment are provided, and can by the scope of the present disclosure complete convey to those skilled in the art.
Main thought of the present invention is, by described IP address translation being become to the numeric string of specific system; The numeric string of described specific system of take is basis, and the question blank that inquiry is set up is in advance interval to determine the numeric string under described numeric string; And the numeric string based under described numeric string is interval, determine the region information of home location of described IP address.
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and corresponding accompanying drawing, technical solution of the present invention is clearly and completely described.Obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
In an implementation, for example, can determine by the following method the detailed information of home location of IP address.First, collect the IP mapping dictionary of better address, object lesson is as follows: IP:123.0.0.1 economizes: Beijing: Beijing district: address, Chaoyang: No. 6, winebibber's bridge road institute's Electronic Science And Technology Building.Then each IP is thought to the combination of series of sign, for example: 123.0.0.1 can be understood as 1,2,3., 0., 0., the combination of 1 these nine symbols.Again, can utilize several different methods to set up queries dictionary, for example: utilize a specific algorithm (for example md5 algorithm, hash algorithm etc.) to be converted into the character string of certain length-specific " 123.0.0.1 " these nine symbols; Key using this character string as dictionary, corresponding detailed content (is economized: Beijing: Beijing district: address, Chaoyang: No. 6, winebibber's bridge road institute's Electronic Science And Technology Building) as the value of dictionary, set up a queries dictionary.Finally, when certain actual user's IP access, first system utilizes the algorithm of setting up dictionary key IP to be converted into the character string of certain length-specific, then by the inquiry in dictionary, obtains the actual address of this actual user IP, then returns to access side.
But there is following shortcoming in this implementation:
(1) prior art is converted into character string by existing certain methods by IP, but the method often transforming is not simple mathematical operation, in conversion process, can have certain efficiency losses.
(2) in practice, often certain particular address has a plurality of IP, so just need to carry out to each IP the foundation of dictionary key, increased the quantity of dictionary key, causing actual queries speed, slack-off (speed of any querying method is to be all directly proportional to the quantity of the key of dictionary, the quantity of the key of dictionary is more, and inquiry velocity is slower).
(3) by IP address spaces, be that character string need to guarantee uniqueness, the method for transformation using in prior art likely can not guarantee uniqueness when IP data are huge, thereby cause different IP to be converted to same character string, this will cause system identification mistake, cannot guarantee the correct identification of system.
Below with reference to the accompanying drawings, describe the improved technical scheme of the present invention in detail.
As shown in Figure 1, Fig. 1 is the process flow diagram of method of identifying according to an embodiment of the invention the region information of home location of IP address.
At step S110 place, obtain user's IP address.
Particularly, in service application, obtain user's IP address.For instance, for example a user opens a website and browses, and by server operation, obtains user's IP address.
At step S120 place, described IP address translation is become to the numeric string of specific system.
Particularly, get behind user's IP address, IP address need to be changed to obtain the numeric string of specific system.Alternatively, in one embodiment of the invention, IP address translation can be become to metric ten binary digit strings.
For example, the user's who gets IP address is IP:123.0.0.2, by the decimal system, IP is converted into the integer of 12, for example: 123.0.0.2 is converted to 123000000002.
Should be appreciated that, the invention is not restricted to this, but can also adopt other any suitable systems that each IP is transformed into a numeral.
Next, at step S130 place, numeric string based on this specific system, the question blank that inquiry is set up is in advance interval to determine the numeric string under this numeric string, wherein, it is interval that question blank comprises one or more numeric strings, and each numeric string interval is corresponding with the region information of home location of the IP address of a specific region.
Particularly, for example as shown in Figure 3, it is interval that question blank comprises a plurality of numeric strings:
[123000000004，123000000001]
[124000000003，124000000001]
[125000000006，125000000002]
[126000000010,126000000001] etc.
Wherein, for example, the interval IP address with Beijing of the first two numeric string region information of home location---Beijing is corresponding; The interval IP address with Shanghai City of third digit string region information of home location---Shanghai City is corresponding; The interval IP address with Guangzhou of fourth digit string region information of home location---Guangzhou is corresponding.
Alternatively, each numeric string interval can define by maximum number word string and the minimum number word string at the interval two ends of numeric string.For example third digit string interval is included in the numeric string between [125000000006,125000000002], and its maximum number word string 125000000006 and minimum number word string 125000000002 by the interval two ends of this numeric string defines.
After having understood the implication in numeric string interval, next specifically describe numeric string based on described specific system and inquire about the question blank set up in advance to determine the process in the numeric string interval under this numeric string.
First, numeric string that can be based on described specific system, searches described question blank to determine the maximum number word string nearest with the numeric string of described specific system.Particularly, the maximum number word string in each numeric string interval in the numeric string of described specific system and described question blank can be compared determine the maximum number word string nearest with the numeric string of described specific system.
Accept example, the numeric string that user's IP address converts to is 123000000002, searches question blank and determines that the maximum number word string nearest with this numeric string is 123000000004.
Then, the maximum number word string 123000000004 based on definite, determines that the numeric string interval under this maximum number word string is [123000000004,123000000001].
Should be appreciated that, the invention is not restricted to this, but can also adopt any other suitable method to determine the maximum number word string nearest with this numeric string.
Next, judge whether the numeric string of described specific system is greater than the minimum number word string in this numeric string interval.Alternatively, for example the corresponding numeric string 123000000002 in the IP address with user can be compared to determine with the minimum number word string 123000000001 in this numeric string interval whether it is less than the minimum number word string in this numeric string interval.
Should be appreciated that, the invention is not restricted to this, but can also adopt any other suitable method to determine whether this numeric string is greater than the minimum number word string in this numeric string interval.
If be greater than the minimum number word string in this numeric string interval, determine that this numeric string belongs to described numeric string interval.
Continue example above, can see, the numeric string 123000000002 corresponding with user's IP address is greater than the minimum number word string 123000000001 in this numeric string interval.Therefore determine that this numeric string 123000000002 belongs to numeric string interval [123000000004,123000000001].
Can be referring to the detailed description of Fig. 2 after a while about the process of establishing of question blank.
Next, at step S140 place, the numeric string based under this numeric string is interval, determines the region information of home location of this IP address.
Particularly, alternatively, the numeric string based under this numeric string is interval, obtains corresponding with it region information of home location, then, described region information of home location is defined as to the region information of home location of described IP address.
For example, by the corresponding relation between numeric string interval and region information of home location in question blank, can know that interval [123000000004,123000000001] the corresponding region information of home location of numeric string is Beijing.Then, by this region information of home location---Beijing is defined as the region information of home location of user's IP address 123.0.0.2.
The method of the region information of home location of identifying according to an embodiment of the invention IP address has so far been described.About the process of establishing of question blank wherein, below in conjunction with Fig. 2, be described in detail.
With reference to Fig. 2, wherein show the process flow diagram of the method for setting up according to an embodiment of the invention question blank.
As shown in Figure 2, at step S210 place, by the IP address in database each convert the numeric string of corresponding described specific system to, in wherein said database, comprise the information of home location of IP address, IP address and the corresponding relation of the two.
In order more clearly to describe the process set up question blank, the schematic diagram of the corresponding relation of and region information of home location interval below with reference to the numeric string of Fig. 3 is described.
As shown in Figure 3, for example by the IP address in database each convert the numeric string of corresponding described specific system to.For example, in one embodiment of the invention, convert thereof into metric ten binary digit strings.For example, an IP address 123.0.0.1 in database, the information of home location of this IP address is: economize: Beijing; Beijing district: Chaoyang; Address: No. 6, winebibber's bridge road institute's Electronic Science And Technology Building, and this IP address is corresponding with its information of home location.
According to method of the present invention, convert IP address 123.0.0.1 to metric ten binary digit strings 123000000001.In the same way, all convert IP addresses all in database to numeric string.
At step S220 place, based on presumptive area division rule defined region information of home location and IP address-based information of home location, the numeric string of the corresponding specific system in IP address is mapped to region information of home location.
Particularly, presumptive area division rule can Shi Yi city be for example the rank of region division rule, defined range information of home location.That is to say, Beijing is a region information of home location, Shanghai City is another region information of home location, other cities are also similarly divided, then based on this region information of home location and IP address-based information of home location, the numeric string of the corresponding specific system in IP address is mapped to region information of home location.
With reference to figure 3, accept example above, for example there is the corresponding following character string in IP address: 123000000004,123000000002,123000000001,124000000003,124000000001,125000000006,125000000005,125000000002,126000000010,126000000009,126000000008,126000000001.Equal corresponding Shanghai City of information of home location of the equal corresponding Beijing of the information of home location of 1-5 numeric string, a 6-8 numeric string wherein, the equal corresponding Guangzhou of information of home location of 9-12 numeric string.
Should be appreciated that, in actual applications, IP address, information of home location and region information of home location can comprise greater number.
Thereby the region information of home location based on each city-level, and the information of home location based on above-mentioned numeric string, is mapped to region information of home location by 1-5 numeric string---Beijing, 6-8 numeric string is mapped to region information of home location---Shanghai City is also mapped to region information of home location by 9-12 numeric string---Guangzhou.
Should be appreciated that, above-mentioned example is only that schematically the present invention is not limited to this, but can have any number of numeric strings and certain region information of home location to shine upon mutually.
Be also to be understood that region of the present invention information of home location is not limited to this, but can also adopt any other other region of level to define other other region information of home location of level as region division rule.For example, can using North China, south China, northeast, northwest, southwest, East China etc. region rank carries out the division of region information of home location as the rank of region division rule.
Next, at step S230 place, by being mapped to the numeric string of each region information of home location, form the one or more numeric strings interval corresponding with this region information of home location, wherein each numeric string interval utilizes maximum number word string and the minimum number word string at the interval two ends of numeric string to define.
With reference to figure 3,1-5 the numeric string that is mapped to region, Beijing information of home location formed two numeric string intervals [123000000004,123000000001] and [124000000003,
124000000001] 6-8 the numeric string that, is mapped to region, Shanghai City information of home location formed a numeric string interval [125000000006,125000000002] 9-12 the numeric string that, is mapped to region, Guangzhou information of home location formed a numeric string interval [126000000010,126000000001].
Should be appreciated that, above-mentioned example is only that schematically the present invention is not limited to this, but each region information of home location may be corresponding with one or more numeric strings interval.
The number that be also to be understood that the numeric string interval that the numeric string corresponding with same region information of home location forms is not only between above-mentioned digital block, and the present invention is not limited to this.According to the present invention, it is in the light of actual conditions or according to the mode of optimizing to carry out suitably adjusting that the numeric string corresponding with same region information of home location forms how many numeric strings interval.
Finally, at step S240 place, the corresponding relation based on numeric string interval with region information of home location,
Set up described question blank.
Particularly, as shown in Figure 3, all numeric strings interval obtaining is mapped with region information of home location, the corresponding relation based on them, sets up question blank.
