Any IP data source comprises a plurality of IP sections, that is, each IP data source comprises a plurality of IP sections, and each IP section comprises one section of IP address.IP data source can crawl by network, also can be by buying acquisition to operator.IP data source can be 2 IP data sources, can be also 2 above a plurality of IP data sources.
Step S202, generates IP number axis, and IP number axis comprises all IP address.Because IP address is a denumerable set, its scope is 0.0.0.0 to 255.255.255.255, as shown in Figure 3, generate an IP number axis by 0.0.0.0 to 255.255.255.255, the direction of the order of the IP of direction indication shown in arrow address arrangement in figure, is arranged on all IP address in denumerable sets on this IP number axis in order accordingly.Because IP address is a denumerable set, the form of the tables of data that therefore this IP number axis can be by database presents, for example, by each IP address spaces, be shaping data, these shaping data are not repeatedly inserted in tables of data in order, and this tables of data just can be called IP number axis so.It should be noted that, the IP number axis here, also can be called IP question blank, IP tables of data, or other for representing, the IP address set of arranging is integrated in all IP address, " IP number axis " here do not have improper restriction to the present invention.
Step S203, is mapped to the starting point of each the IP section in a plurality of IP data sources and end point respectively on IP number axis.Owing to comprising all IP addresses on above-mentioned IP number axis, each IP section all has one section of corresponding IP section of an IP section on this IP number axis.Each IP section includes a starting point and an end point, and the starting point of obtaining and end point are starting point and the end point of each the IP section in each IP data source.The one IP section comprises a plurality of IP address, therefore, and all corresponding IP address of the starting point of each IP section or end point.The starting point of each the IP section in each IP data source and end point are mapped to respectively on the corresponding IP of IP number axis address, when IP number axis is while comprising the IP tables of data of all IP address, be the starting point of each the IP section in each IP data source and end point are mapped to respectively on the corresponding IP of IP tables of data address.Owing to comprising all IP addresses on IP number axis, so the starting point of any the IP section in any one IP data source or end point all have a corresponding IP address on IP number axis.
Step S204, using starting point corresponding on IP number axis and end point as boundary point.This boundary point is used for dividing IP data source, due to all starting points and IP address corresponding to end point are mapped to respectively on the IP address that IP number axis is corresponding, therefore, on IP number axis, have corresponding starting point and end point, using the starting point on this IP number axis and end point as boundary point, wherein, if duplicated between starting point or end point, or between starting point and end point, duplicate, so using all repetitions o'clock as a boundary point.
Step S205, the IP address field between two boundary points adjacent on IP number axis take as the 2nd IP section that to divide IP data source be a plurality of the 2nd IP sections.Between each boundary point, include one section of IP address field, that is to say IP section, using this IP address field as the 2nd IP section, that is to say new IP section, to realize repartitioning each IP data source.
Preferably, step S205 can comprise the following steps:
Step S2051, contrasts IP address field and an IP section.Due to and whether the IP section in each IP data source comprised all IP address, therefore can exist the IP address field after dividing according to boundary point not to be present in any one IP data source, each IP address field between every two adjacent boundary points after dividing and each the IP section in original a plurality of IP data source are contrasted, so that judge whether this IP address field is present in original IP data source.
Step S2052, judges on IP number axis, whether IP address field is present in any IP section.According to the comparing result after IP address field and an IP section are contrasted, judge whether this IP address field is present in any the IP section in any one IP data source.This deterministic process is the process that the IP address field after splitting is recalled, and confirms whether the IP address field after splitting is present in former IP data source.For example, certain two adjacent boundary point is the end point of the IP section in original IP data source and the starting point of another IP section, IP address field between this end point and starting point does not belong to any one IP data source, this IP address field can not be as the 2nd IP section, that is, can not be as the new IP section after new fractionation.
Step S2053, if IP address field is present in any IP section, using IP address field on IP number axis as the 2nd IP section.Only have this IP address field of working as to be present in an IP section, using this IP address field as the 2nd IP address field, that is, and new IP section.If this IP address field is not present in any IP section, show not have this section of IP address in original a plurality of IP data sources., not using this IP address field as the 2nd IP section, continue to judge whether next IP address field is present in any IP section.
According to the embodiment of the present invention, IP address field after dividing and the IP section in IP data source are contrasted, reject and be not present in the IP address field in original IP data source, make the IP data source after repartitioning and divide the total IP address comprising in previous IP data source to be consistent.
Preferably, after execution of step S205, the processing method of IP data source also comprises that step is as follows:
Step S6, obtains the attaching information of the IP data source of an IP section correspondence, and attaching information comprises geography information and operator's information.The one IP section is each the IP section in each IP data source, obtain the attaching information of each IP section, this attaching information can be geography information or operator's informaiton, operator also can claim ISP(Internet Service Provider, ISP, be called for short ISP), for example, geography information corresponding to an IP section B in some IP data sources is Beijing.
Step S7, determines the attaching information of the 2nd IP section according to attaching information.Because the 2nd IP section is that a plurality of IP sections in a plurality of IP data sources are repartitioned and obtained, therefore according to the attaching information of an IP section, can determine the attaching information of the 2nd IP section.In addition, the 2nd IP section may be present in a plurality of IP data sources, and therefore the 2nd IP section after dividing can include a plurality of different geography information or operator's informaiton.For example, geography information corresponding to the one IP section C is Tianjin, the corresponding geography information of the one IP section D is Tangshan City, wherein, the one IP section C and an IP section D are respectively the IP section in different IP data source, and there is crossing situation between an IP section C and an IP section D, after disposal methods through the IP data source in the embodiment of the present invention, the one IP section C is split as to the 2nd IP section X and the 2nd IP section Y, the one IP section D is split as the 2nd IP section X and the 2nd IP section Z, so, can find out, the 2nd IP section X had both been present in an IP section C, also be present in an IP section D simultaneously, the geography information that the 2nd IP section X is corresponding so may be Tianjin, also may be Tangshan City, here all geography information that may be corresponding that can its correspondence of mark, so that further determine its ownership.Geography information corresponding to the 2nd IP section Y is Tianjin, and geography information corresponding to the 2nd IP section Z is Tangshan City.
