IP location technology determines the geographic location of a device by its IP address. The existing IPv4 geographical position positioning method is mainly researched and experimented from the aspects of network delay, AS path, registration information, commercial database, user data and the like, and has the national level accuracy rate of 99.99 percent and the provincial accuracy rate of more than 90 percent. At present, IPv4 positioning is mature, and the method is widely applied to the fields of network management, targeted advertisement delivery, social networks and the like.
IPv6 geolocation is the physical spatial location of IPv6 addresses by measurement or other technical means. With the wide use of the current IPv6 in the global scope and the high importance of China on the IPv6 deployment, the IPv6 geographical position positioning has very important application prospect and value in multiple aspects. For example: content localization, advertisement delivery, content distribution networks, network fault diagnosis, network attack tracing, and the like.
The existing IPv6 address positioning research is to apply the traditional IPv4 address positioning method to IPv6 addresses, the method is mainly classic network delay measurement, namely, a 'delay-geographic distance' mathematical model is constructed through the network delay measurement and multipoint positioning is carried out.
The network delay measurement is very dependent on the number of landmark points and the geographical position distribution, but at first, the domestic IPv6 address has low utilization rate and few active addresses, and does not have the condition of large-scale network detection; secondly, the number of the landmark points used in the existing research is only 29 in the global scope, and China only has one hong Kong node, the positioning granularity is thicker and is only in the national level; and thirdly, the data is single in type.
In order to solve the above problems, this specification provides an IPv6 geographic location method, an apparatus, a device, and a storage medium, where when locating an IPv6 geographic location, an IPv6 address to be located is first obtained, a flag bit code of the IPv6 address to be located is then determined, and an IPv6 geographic location corresponding to the IPv6 address to be located is further determined based on the flag bit code of the IPv6 address to be located and a table of correspondence between the flag bit code and the geographic location, that is, the IPv6 geographic location is performed. The method and the device can be applied to various electronic devices such as mobile phones and tablet computers, and are not limited specifically.
For the convenience of understanding, the IPv6 geographical location positioning method is described in detail below with reference to the accompanying drawings.
It should be noted that the IPv6 address mentioned below is a domestic IPv6 address, and the IPv6 address block is a domestic IPv6 address block.
Fig. 1 is a schematic flow chart of an IPv6 geographical location positioning method provided in this specification, where the method includes:
s01, acquiring the IPv6 address to be positioned.
In this embodiment, the IPv6 address to be located refers to an IPv6 address that needs to be located at a geographic location. In practical application, the IPv6 address to be located may be one or more IPv6 addresses, or one or more IPv6 address blocks, and is not limited specifically.
In order to perform IPv6 geographical location positioning based on an IPv6 address, an electronic device (hereinafter referred to as the electronic device) executing the method needs to first acquire an IPv6 address to be positioned.
S02, determining the zone bit code of the IPv6 address to be positioned based on the IPv6 address to be positioned.
In this embodiment, the flag bit refers to the number of bits of the code indicating the geographical location of the IPv6 address in the IPv6 address code, for example, the number of bits may be 10 to 15 bits in the IPv6 address code, or may be 12 to 17 bits in the IPv6 address code, and the like, which is not limited specifically.
The zone bit code refers to the code at the zone bit of the IPv6 address code indicating the geographical position of the IPv6 address. The flag bit codes of different IPv6 addresses can be the same or different, and when the flag bit codes of two IPv6 addresses are the same, the geographical positions of the two IPv6 addresses are the same.
In order to locate the geographical position of the to-be-located IPv6 address, after the to-be-located IPv6 address is acquired, the flag bit code of the to-be-located IPv6 address can be further determined.
The geographical position flag bits of the domestic IPv6 addresses are basically the same under the general condition, which is deduced through experiments on a large number of IPv6 addresses and the corresponding geographical positions thereof. Therefore, the geographical location flag of the IPv6 address can be firstly determined according to the IPv6 addresses of a large number of geographical locations covering provinces, cities and counties in China. After the IPv6 address to be positioned is obtained, the zone bit code of the IPv6 address to be positioned can be directly obtained according to the code of the IPv6 address to be positioned.
S03, determining the IPv6 geographical position corresponding to the IPv6 address to be positioned according to the pre-established flag bit code and geographical position corresponding relation table based on the flag bit code of the IPv6 address to be positioned.
In this embodiment, the correspondence between the flag bit code of the IPv6 address and the geographical position of the IPv6 address is recorded in the table of correspondence between the flag bit code and the geographical position; in practical application, a large number of IPv6 addresses of geographical positions covering provinces, cities and counties in China can be obtained in advance, then the zone bit codes of all IPv6 addresses are determined respectively, and further a corresponding relation table of the zone bit codes and the geographical positions is established.
The following detailed description will be made about the establishment process of the flag bit code and geographical location correspondence table, and will not be described herein again.
After the zone bit code of the IPv6 address to be positioned is obtained, the geographical position relation corresponding to the zone bit code can be determined based on the zone bit code and geographical position corresponding relation table, namely the geographical position of the IPv6 address to be positioned is determined.
It can be understood that the flag bit codes of the IPv6 addresses to be positioned are determined, and then the IPv6 geographical position positioning is carried out based on the flag bit codes and the geographical position corresponding relation table, and the domestic IPv6 geographical position positioning is realized independent of the number of landmark points and the geographical position distribution thereof.
In practical application, in order to locate the IPv6 address to be located, a corresponding relation table between the flag bit codes and the geographic locations may be pre-established; then, fig. 2 is a schematic flowchart of a method for establishing a corresponding relationship table between a flag bit code and a geographic location provided in this specification, as shown in fig. 2, in some possible embodiments, the method for establishing the corresponding relationship table between the flag bit code and the geographic location includes:
s21, respectively preprocessing each IPv6 address in a pre-established IPv6 address-geographical position table to obtain each preprocessed IPv6 address; the IPv6 address-geographical position table comprises geographical positions corresponding to all IPv6 addresses;
s22, entropy analysis is carried out on each preprocessed IPv6 address respectively to obtain alternative geographical position zone bits of each IPv6 address;
s23, clustering and dividing all IPv6 addresses in the IPv6 address-geographical position table according to geographical positions to obtain geographical position classifications of all IPv6 addresses in the IPv6 address-geographical position table;
s24, determining the geographical position zone bit of each IPv6 address in the IPv6 address-geographical position table based on the alternative geographical position zone bit of each IPv6 address and the geographical position classification of each IPv6 address;
s25, determining the zone bit codes of all IPv6 addresses in an IPv6 address-geographical position table based on the geographical position zone bits of all IPv6 addresses, and establishing a zone bit code and geographical position corresponding relation table based on the geographical positions corresponding to all IPv6 addresses in the IPv6 address-geographical position table.
In practical application, the IPv6 address-geographic location table can be established in advance according to website data of web pages with known geographic locations and real IPv6 data of clients, and the IPv6 address-geographic location table includes a large number of IPv6 addresses and geographic locations thereof.
The IPv6 address-geographic location table establishing method will be described in detail later, and will not be described in detail herein.
Firstly, preprocessing each IPv6 address in an IPv6 address-geographical position table respectively, uniformly converting the format of each IPv6 address into a 32-bit nibble format, and removing ":"; for example, the IPv6 address "2401: ec00:3002:1: 2ad3: aa1 a" will become "2401 ec0030020001000000002ad3aa1 a" after pretreatment.
Then, entropy analysis is applied to entropy of each preprocessed IPv6 address, and a formula is as follows:
wherein, H (X)i) Entropy value, X, representing the ith nibble positioni∈{x1,…,xk}；P(xj) Denotes the value of the ith nibble bit as xjThe probability of (c).
After entropy is carried out on each preprocessed IPv6 address, each preprocessed IPv6 address is divided from a nibble bit which simultaneously meets the following two conditions:
first, H (X)i) And H (X)i-1) By contrast, crossing any one of the set of thresholds T, where T ∈ T, 0<t<1, and are arranged from small to large;
secondly, calculating an absolute value d of the difference of the entropy values of two adjacent nibble positions, wherein d needs to satisfy the following formula:
|H(Xi)-H(Xi-1)|＞Th
wherein, ThThe minimum limit of the absolute value d of the difference value of the entropy values of two adjacent nibble positions is defined; e.g. ThThe value of (b) may be 0.05, and is not particularly limited.
In practical application, T and ThThe value of (a) can be adjusted correspondingly according to the actual data in the IPv6 address-geographic location table to obtain the correct zone bit.
After entropy analysis is carried out on each preprocessed IPv6 address, the alternative geographical position zone bits of each IPv6 address in the IPv6 address-geographical position table can be obtained.
Correspondingly, each preprocessed IPv6 address needs to be classified according to provinces and cities based on the geographical location corresponding to each address. Aiming at the alternative geographical position zone bits of all IPv6 addresses in the IPv6 address-geographical position table, further determining that the zone bits encode the same bit number under the same geographical position classification, namely the geographical position zone bits of all IPv6 addresses in the IPv6 address-geographical position table; it should be noted that, as deduced through experiments on a large number of IPv6 addresses and corresponding geographic locations thereof, the geographic location flag bits of the domestic IPv6 addresses are basically the same under normal conditions, and therefore, after the geographic location flag bits of the IPv6 addresses in the IPv6 address-geographic location table are determined, the geographic location flag bits are the same as the geographic location flag bits of the domestic IPv6 addresses.
After the geographical position zone bits of all IPv6 addresses in the IPv6 address-geographical position table are determined, zone bit codes of all IPv6 addresses in the IPv6 address-geographical position table can be determined according to the geographical position zone bits of all IPv6 addresses, and then the mapping relation between the zone bit codes and the geographical positions is established according to the geographical positions corresponding to all IPv6 addresses in the IPv6 address-geographical position table, namely the zone bit code and geographical position corresponding relation table is established.
It can be understood that starting from an IPv6 address hierarchical structure, entropy analysis and cluster division are carried out on IPv6 addresses without depending on the physical space of IPv6 addresses, geographical position zone bits of IPv6 addresses are determined, a zone bit coding and geographical position corresponding relation table is established, geographical position location of IPv6 addresses is carried out based on the zone bit coding and geographical position corresponding relation table, and the problem of coarse granularity of IPv6 address location methods in the prior art is solved.
In some possible embodiments, the method for establishing the IPv6 address-geographic location table includes:
acquiring website data of a plurality of webpages with known geographic positions; the data of each website respectively comprises the IPv6 address of a webpage with a known geographic position;
acquiring real IPv6 data of a plurality of clients; the real IPv6 data of each client respectively comprise a real IPv6 address and longitude and latitude corresponding to each client;
and establishing an IPv6 address-geographic position table based on the website data of the webpages with the known geographic positions and the real IPv6 data of the clients.
In practical application, on one hand, a large number of domain name lists which cover domestic provinces and cities and comprise domestic famous website domain names, college website domain names, government website domain names and the like can be obtained through the webpage crawler; then, searching whether each domain name in the domain name list has an AAAA record by using nslookup, if so, recording a record value of the AAAA record, wherein the record value of the AAAA record is the IPv6 address of the webpage corresponding to the domain name with the AAAA record; then crawling a website with an IPv6 address, and analyzing the webpage title, the webpage content and the like to obtain the geographical position information of the website; further establishing a domain name address table, and storing website data such as the IPv6 address of each website, the domain name of the website, the content of the website, the geographical location of the website, and the like, which are not limited specifically.
On the other hand, a large amount of real IPv6 data covering the clients of various provinces and cities in China can be collected, the real IPv6 data of each client respectively includes the client IPv6 address and longitude and latitude information associated with the data, and then the corresponding geographic location information is obtained through the longitude and latitude query application program interface, for example, the country, province, city, county, and the like, which is not limited specifically. In practical applications, the application program interface may be a Baidu map application program interface or a Gade map application program interface, and is not limited specifically.
The website data comprises the IPv6 address and the geographic position corresponding to the website, the real IPv6 data of the client comprises the IPv6 address and the longitude and latitude information of the client which are related to the real IPv6 data of the client, and an IPv6 address-geographic position table can be established according to the website data of a plurality of webpages with known geographic positions and the real IPv6 data of the plurality of clients.
It can be appreciated that errors generated by relying on a single kind of data are reduced by building an IPv6 address-geographic location table using website data and client real IPv6 data.
As a possible implementation, the method further includes:
and based on the IPv6 address to be positioned, determining the distribution geographical position and the routing geographical position corresponding to the IPv6 address to be positioned according to a pre-established IPv6 address block-geographical position table.
In practical application, the IPv6 address block-geographical location table may be established in advance according to IPv6 allocation data and IPv6 routing data, and the IPv6 address block-geographical location table includes the distribution mechanism name, the distribution mechanism geographical location, and the routing geographical location of a large number of IPv6 address blocks.
It can be understood that after the IPv6 address to be positioned is obtained, the assigned geographic position and the routing geographic position of the IPv6 address to be positioned can be further obtained according to the IPv6 address block-geographic position table, which is beneficial to obtaining more positioning information about the IPv6 address to be positioned.
In one possible implementation, the method for establishing the IPV6 address block-geographic location table includes:
acquiring IPv6 distribution data based on an APNIC Whois database; wherein the IPv6 allocation data comprises the allocation mechanism name and the allocation mechanism geographical position of a plurality of IPv6 address blocks;
acquiring a plurality of IPv6 routing data; each IPv6 routing data respectively comprises IPv6 routing information, IPv6 address blocks related to the IPv6 routing information and geographical positions of the IPv6 address blocks;
and establishing an IPv6 address block-geographical position table based on the IPv6 distribution data and a plurality of IPv6 routing data.
The APNIC Whois database is a publicly searchable database that specifies the APNIC's digital Internet resource records, i.e., IP address assignments and AS numbers, within the administrative domain of the Asia-Pacific region. Each record contains many different objects, for example: AS number, IPv6 address field, person, etc. Objects may reference other objects. The inet6num object mainly describes the allocation and assignment information of the IPv6 address block, and the object comprises a plurality of attributes such as count, descr, admin-c, tech-c, mnt-by and the like.
In practical application, on one hand, the IPv6 distribution data may be first obtained through the APNIC Whois database, and the obtaining process is as follows:
an IPv6 address block allocation information table and an IPv6 address block allocation address table are established. Analyzing each inet6num object in the APNIC Whois database, wherein each inet6num object corresponds to an IPv6 address block and related distribution information thereof. Analyzing the country attribute, and searching a country code to obtain the English name of the country; analyzing the descr attribute to obtain mechanism information, and extracting mechanism geographical position related information in the descr attribute. The admin-contact attribute in the inet6num object represents a management contact, the attribute refers to a person or role object, when the attribute is analyzed, the address attribute in the person or role object is analyzed, and the possibly existing organization name and organization geographical position information are extracted; analyzing the e-mail attribute, and extracting the possibly existing organization name and organization geographical position information; and analyzing the attribute of the phone, wherein the attribute is mostly fixed phone, and searching the number rule to obtain the geographical position information of the organization. The mnt-by attribute of the inet6num object refers to the mntner object, analyzes the descr attribute in the mntner object, and extracts the organization name and the organization geographical location information that may exist therein. The mnt-irt attribute of the inet6num object refers to the irt object, analyzes the address, phone and other attributes of the irt object, and extracts the name and geographical location information of the organization which may exist in the attribute. The org attribute of the inet6num object refers to the organization object, and analyzes the attributes of address, phone, etc. of the organization object. The name of the organization and the geographical location information of the organization possibly existing in the name of the organization are extracted.
After the inet6num objects of all IPv6 address blocks in the APNIC Whois database are analyzed, all attribute information obtained in the analysis process is stored under the corresponding IPv6 address blocks in a pre-established IPv6 address block distribution information table; meanwhile, various organization names and organization geographical position information obtained by analyzing the attributes are stored under the corresponding IPv6 address blocks in the IPv6 address block distribution address table.
Analyzing an IPv6 address block distribution address table, recording a plurality of corresponding mechanism names and mechanism geographical position information for the same IPv6 address block, judging whether the mechanism names are the same family or not through text analysis, and judging whether the mechanism geographical positions are the same or not; and if the authority names and the authority geographical position information are the same, saving the authority names and the authority geographical position information as the final distribution mechanism names and the final distribution mechanism geographical position information. And if the names of the mechanisms are judged not to be the same or the geographical positions of the mechanisms are judged to be different, selecting the mechanism name and the mechanism geographical position with the largest occurrence frequency as the distribution mechanism name and the distribution mechanism geographical position according to the proportion of the mechanism name information and the mechanism geographical position information. If the analyzed result shows that the address block in the IPv6 address block allocation address table does not record organization name information and geographical location information, the inet6num _ descr in the IPv6 address block allocation information table is used as the name information of the allocation organization and the inet6num _ count is used as the geographical location information.
