IP地址地理位置定位技术是确定Internet中IP设备的地理位置的方法，IP地址地理位置被广泛用于广告投放、网站分析、智能路由、网络犯罪研究。随着IPv6大规模的部署，IPv6地址地理定位数据库的需求也越来越大，传统IPv4地址地理定位方法在IPv6稀疏的地址空间已经不适用。IP address geographic location technology is a method to determine the geographic location of IP devices on the Internet. IP address geographic location is widely used in advertising, website analysis, intelligent routing, and cybercrime research. With the large-scale deployment of IPv6, the demand for IPv6 address geolocation database is also increasing. The traditional IPv4 address geolocation method is no longer suitable for the sparse IPv6 address space.

传统的IPv6地址的地理位置定位方法主要分为以下三种：The traditional geographical positioning methods of IPv6 addresses are mainly divided into the following three types:

1)通过对权威数据库和商用数据库中地理位置相关信息的自动化分析获取IPv6地址地理位置信息；1) Obtain the geographic location information of IPv6 addresses through automatic analysis of geographic location-related information in authoritative databases and commercial databases;

2)通过收集开启定位服务功能的客户端的GPS等信息获取IPv6地址的地理位置；2) Obtain the geographic location of the IPv6 address by collecting information such as the GPS of the client with the location service function enabled;

3)通过主动探测的方法，根据时延和地理距离的关系，结合网络拓扑信息推测IP地址的地理位置。3) Through the method of active detection, according to the relationship between time delay and geographical distance, combined with network topology information to infer the geographical location of the IP address.

但是，由于权威公开数据库的主要目的是提供互联网资源注册管理，而非IPv6定位，因此仅记录了IPv6相关机构的地理位置属性；另外在商用数据库中，IPv6地理位置定位精度仅在国家级别，并未到达省市。可用的IPv6地址定位的数据库少、信息少。However, since the main purpose of the authoritative public database is to provide Internet resource registration management rather than IPv6 positioning, only the geographic location attributes of IPv6-related institutions are recorded; in addition, in commercial databases, the accuracy of IPv6 geographic location positioning is only at the national level, and Provinces and cities have not been reached. There are few databases and little information on available IPv6 address location.

IPv6地址空间大，近年来在飞速发展，全球都在加快其部署，但是IPv6网络稀疏，活跃度低，通过客户端的GPS等信息获得的活跃地址太少。The IPv6 address space is large, and it has been developing rapidly in recent years, and its deployment is being accelerated all over the world. However, the IPv6 network is sparse and active, and there are too few active addresses obtained through the client's GPS and other information.

基于网络探测的定位方法需要有大量且地理位置分布均匀的已知地理位置的节点用于探测，但目前没有公开的IPv6探测节点。The positioning method based on network detection requires a large number of nodes with known geographic locations and evenly distributed geographic locations for detection, but there is currently no public IPv6 detection node.

因此，亟需能够对IPv6地址进行高效的地理定位的方法。Therefore, there is an urgent need for a method capable of efficiently geolocating IPv6 addresses.

为了解决上述问题，本公开提供了一种基于IPv4地址地理位置信息的IPv6地址定位方法及电子设备，该方法包括通过分析IP路由前缀归属自治系统的城市覆盖度建立IPv6路由前缀-地理位置信息映射，分析IPv6地址的接口标识中嵌入IPv4地址的特征建立第一IPv6地址-地理位置信息映射，基于位置语义分析获得IPv6地址反向解析字符串涵盖的地理位置信息建立第二IPv6地址-地理位置信息映射，基于智能推断获得IPv4地址和IPv6地址同源的关联关系建立第三IPv6地址-地理位置信息映射，然后基于IPv6路由前缀-地理位置信息映射、第一IPv6地址-地理位置信息映射、第二IPv6地址-地理位置信息映射和第三IPv6地址-地理位置信息映射，创建IPv6地址地理位置库，最后将待定位IPv6地址输入IPv6地址地理位置库，即可得到所述待定位IPv6地址对应的地理位置；该方法可以应用于桌面计算机、移动电脑、手机、平板电脑、计算机、智能可穿戴设备、个人数字助理等，具体不做限定。In order to solve the above problems, the present disclosure provides an IPv6 address location method and electronic equipment based on IPv4 address geographic location information, the method includes establishing IPv6 routing prefix-geographic location information mapping by analyzing the city coverage of the autonomous system that the IP routing prefix belongs to , analyze the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address to establish the first IPv6 address-geographic location information mapping, and obtain the geographic location information covered by the reverse parsing string of the IPv6 address based on the location semantic analysis to establish the second IPv6 address-geographic location information Mapping, based on intelligent inference to obtain the same-source association relationship between IPv4 address and IPv6 address, establish a third IPv6 address-geographic location information mapping, then based on IPv6 routing prefix-geographic location information mapping, first IPv6 address-geographic location information mapping, second IPv6 address-geographic location information mapping and the third IPv6 address-geographic location information mapping, create an IPv6 address geographic location database, and finally input the IPv6 address to be located into the IPv6 address geographic location database to obtain the geographic location corresponding to the IPv6 address to be located location; the method can be applied to desktop computers, mobile computers, mobile phones, tablet computers, computers, smart wearable devices, personal digital assistants, etc., without limitation.

为了便于理解，下面结合附图对该基于IPv4地址地理位置信息的IPv6地址定位方法进行详细说明。For ease of understanding, the IPv6 address positioning method based on the geographic location information of the IPv4 address will be described in detail below in conjunction with the accompanying drawings.

图1为本公开实施例提供的基于IPv4地址地理位置信息的IPv6地址定位方法的流程示意图；如图1所示，该方法可以包括以下步骤：Fig. 1 is a schematic flow diagram of an IPv6 address location method based on IPv4 address geographic location information provided by an embodiment of the present disclosure; as shown in Fig. 1 , the method may include the following steps:

S11、分析IP路由前缀归属自治系统的城市覆盖度，建立IPv6路由前缀-地理位置信息映射。S11. Analyze the city coverage of the autonomous system to which the IP routing prefix belongs, and establish an IPv6 routing prefix-geographic location information mapping.

自治系统(Autonomous System，简称AS)是在内部采用同一种内部网关协议和统一的度量值转发数据包，在不同自治系统之间采用外部网关协议转发数据包的一组路由器。自治系统是网络的集合，更确切的说是连接这些网络的路由器的集合，这些路由器由同一管理机构进行管理并采用相同的路由策略，简单地说，自治系统可以被认为是由单个管理实体(如大学、政府、商业组织或其他类型的互联网服务提供商(ISP))管理的一组相互连接的IP网络。每个自治系统可以宣告一个或多个IPv4/IPv6路由前缀。An autonomous system (AS for short) is a group of routers that use the same interior gateway protocol and unified metric value to forward data packets internally, and use exterior gateway protocols to forward data packets between different autonomous systems. An autonomous system is a collection of networks, more precisely, a collection of routers connecting these networks. These routers are managed by the same management organization and adopt the same routing strategy. Simply put, an autonomous system can be considered as a single management entity ( A group of interconnected IP networks managed by a university, government, commercial organization, or other type of Internet Service Provider (ISP). Each autonomous system can announce one or more IPv4/IPv6 routing prefixes.

在一些可能的实施方式中，分析IP路由前缀归属自治系统的城市覆盖度，建立IPv6路由前缀-地理位置信息映射，可以包括：通过各自治系统宣告的IPv4路由前缀分别确定各自治系统的覆盖范围，并筛选IPv4路由前缀位于单一城市的自治系统，查询IPv4路由前缀位于单一城市的自治系统对应的IPv6路由前缀，得到IPv6路由前缀-地理位置信息映射。In some possible implementations, analyzing the city coverage of the autonomous system that the IP routing prefix belongs to, and establishing an IPv6 routing prefix-geographic location information mapping may include: respectively determining the coverage of each autonomous system through the IPv4 routing prefix announced by each autonomous system , and filter the autonomous systems with IPv4 routing prefixes located in a single city, query the IPv6 routing prefixes corresponding to the autonomous systems with IPv4 routing prefixes located in a single city, and obtain the IPv6 routing prefix-geographic location information mapping.

作为一种实施方式，分析IP路由前缀归属自治系统的城市覆盖度，建立IPv6路由前缀-地理位置信息映射，可以具体包括：As an implementation manner, analyzing the city coverage of the autonomous system where the IP routing prefix belongs, and establishing IPv6 routing prefix-geographic location information mapping may specifically include:

筛选同时宣告IPv4路由前缀与IPv6路由前缀的自治系统；Filter autonomous systems that announce both IPv4 routing prefixes and IPv6 routing prefixes;

根据IPv4地址地理位置库查询筛选得到的各自治系统中每个IPv4路由前缀的地理位置信息，得到IPv4路由前缀-AS-地理位置信息映射；According to the geographic location information of each IPv4 routing prefix in each autonomous system obtained by querying and filtering the IPv4 address geographic location library, the IPv4 routing prefix-AS-geographic location information mapping is obtained;

对IPv4路由前缀-AS-地理位置信息映射进行自治系统分类，得到AS-地理位置信息映射；Carry out autonomous system classification to IPv4 route prefix-AS-geographic location information mapping, obtain AS-geographic location information mapping;

基于AS-地理位置信息映射，筛选地理位置信息中仅包括单个城市的自治系统；Based on the mapping of AS-geographic location information, filter the geographic location information to include only the autonomous system of a single city;

查询地理位置信息中仅包括单个城市的各自治系统对应的IPv6路由前缀，并根据AS-地理位置信息映射，建立IPv6路由前缀-地理位置信息映射。Only the IPv6 routing prefix corresponding to each autonomous system of a single city is included in the query geographic location information, and an IPv6 routing prefix-geographic location information mapping is established according to the AS-geographic location information mapping.

本公开中，IPv4路由前缀-AS-地理位置信息映射包括IPv4路由前缀、自治系统和基于IPv4地址确定的地理位置信息之间的对应关系。AS-地理位置信息映射包括自治系统和基于IPv4地址确定的地理位置信息之间的对应关系，且在该映射中，每个自治系统的地理位置信息中可能对应1个或多个城市。通过筛选获得仅覆盖单个城市的自治系统，且该自治系统中宣告了IPv6路由前缀，则该自治系统中的IPv6路由前缀与该自治系统覆盖的单个城市对应，即可建立IPv6路由前缀-地理位置信息映射。IPv6路由前缀-地理位置信息映射包括IPv6路由前缀与地理位置信息之间的对应关系。In the present disclosure, the mapping of IPv4 routing prefix-AS-geographical location information includes the correspondence between IPv4 routing prefixes, autonomous systems, and geographic location information determined based on IPv4 addresses. The AS-geographic location information mapping includes the correspondence between autonomous systems and geographic location information determined based on IPv4 addresses, and in the mapping, the geographic location information of each autonomous system may correspond to one or more cities. An autonomous system that only covers a single city is obtained by screening, and an IPv6 routing prefix is declared in the autonomous system, then the IPv6 routing prefix in the autonomous system corresponds to a single city covered by the autonomous system, and the IPv6 routing prefix-geographical location can be established information mapping. The IPv6 routing prefix-geographic location information mapping includes the correspondence between the IPv6 routing prefix and the geographic location information.

图2为本公开实施例提供的IPv6路由前缀-地理位置信息映射的建立流程示例图；如图2所示，首先筛选同时宣告IPv4和IPv6路由前缀的AS，查询筛选得到的AS中各IPv4路由前缀的地理位置信息得到IPv4路由前缀-AS-地理位置信息映射，然后按照自治系统进行分类得到AS-地理位置信息映射，保留地理位置信息中仅包含单个城市的自治系统，舍弃地理位置信息中包括多个城市的自治系统，最后查询地理位置信息中仅包含单个城市的自治系统对应的IPv6路由前缀，并根据AS-地理位置信息映射，获得IPv6路由前缀-地理位置信息映射。Figure 2 is an example diagram of the establishment process of the IPv6 routing prefix-geographic location information mapping provided by the embodiment of the present disclosure; The geographic location information of the prefix is obtained from the IPv4 routing prefix-AS-geographic location information mapping, and then classified according to the autonomous system to obtain the AS-geographic location information mapping. The reserved geographic location information only includes the autonomous system of a single city, and the discarded geographic location information includes For the autonomous systems of multiple cities, the geographical location information of the last query contains only the IPv6 routing prefix corresponding to the autonomous system of a single city, and according to the AS-geographic location information mapping, the IPv6 routing prefix-geographic location information mapping is obtained.

可以理解的是，通过建立IPv6路由前缀-地理位置信息映射，在获取IPv6地址的路由前缀后，能够快速得到该路由前缀对应的地理位置信息。It can be understood that by establishing the IPv6 routing prefix-geographic location information mapping, after obtaining the routing prefix of the IPv6 address, the geographic location information corresponding to the routing prefix can be quickly obtained.

S12、分析IPv6地址的接口标识中嵌入IPv4地址的特征，建立第一IPv6地址-地理位置信息映射。S12. Analyze the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address, and establish a first IPv6 address-geographic location information mapping.

IPv6地址可以清晰地分成两个部分，即用于网络路由的子网前缀(subnetprefix)和用于子网内寻址的接口标识(interface ID，简称IID)。The IPv6 address can be clearly divided into two parts, namely, a subnet prefix (subnet prefix) used for network routing and an interface identifier (interface ID, IID for short) used for addressing within the subnet.

子网前缀是在进行IPv6组网时，终端用户通过互联网服务提供商(InternetService Provider，ISP)、地区互联网注册管理机构(Regional Internet Registry，RIR)、互联网数字分配机构IANA(The Internet Assigned Numbers Authority)等一层一层分配得来。The subnet prefix is used by end users through the Internet Service Provider (Internet Service Provider, ISP), the Regional Internet Registry (Regional Internet Registry, RIR), and the Internet Number Assignment Agency IANA (The Internet Assigned Numbers Authority). Wait for layer by layer to be distributed.

接口标识为64位，用于标识链路上的接口，在每条链路上接口标识必须唯一。接口标识可以通过自动生成或手工生成的方式获得，通过手工生成的接口标识大致可以分为四类：The interface identifier is 64 bits, used to identify the interface on the link, and the interface identifier must be unique on each link. Interface IDs can be obtained automatically or manually. Manually generated interface IDs can be roughly divided into four categories:

1)基于低字节的接口标识生成方案。将接口标识的大部分位都设置为0，只有最后的几字节非零。1) A scheme for generating interface identifiers based on low bytes. Set most of the bits of the interface ID to 0, only the last few bytes are non-zero.

2)基于IPv4地址的接口标识生成方案。例如，将四字节的IPv4地址作为IID最后四个字节。2) A scheme for generating interface identifiers based on IPv4 addresses. For example, take a four-byte IPv4 address as the last four bytes of the IID.

3)基于服务、端口号的接口标识生成方案。例如，将该服务器端口号和编号本身或者十六进制形式直接嵌入到接口标识中。3) Interface identification generation scheme based on service and port number. For example, embed the server port number and the number itself or in hex directly into the interface ID.

4)基于单词的接口标识生成方案。为了便于记忆，也可以使用基于单词的生成方式。4) A word-based interface identification generation scheme. For ease of memory, word-based generation can also be used.

在实际应用中，可以基于对IPv6地址的接口标识的分析，获得IPv6地址的地理位置信息。In practical applications, the geographic location information of the IPv6 address can be obtained based on the analysis of the interface identifier of the IPv6 address.

本公开中，第一IPv6地址-地理位置信息映射是指通过分析IPv6地址的接口标识中嵌入的IPv4地址的特征建立的IPv6地址-地理位置信息映射。第一IPv6地址-地理位置信息映射包括IPv6地址与地理位置信息之间的对应关系。In the present disclosure, the first IPv6 address-geographic location information mapping refers to the IPv6 address-geographic location information mapping established by analyzing the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address. The first IPv6 address-geographic location information mapping includes correspondence between IPv6 addresses and geographic location information.

在一些可能的实施方式中，分析IPv6地址的接口标识中嵌入IPv4地址的特征，建立第一IPv6地址-地理位置信息映射，可以包括：筛选IPv6地址集中基于IPv4地址生成接口标识的IPv6地址，提取筛选得到的各IPv6地址中嵌入的IPv4地址，并确定提取得到的各IPv4地址的地理位置信息，建立第一IPv6地址-地理位置信息映射。In some possible implementation manners, analyzing the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address, and establishing the first IPv6 address-geographic location information mapping may include: screening the IPv6 address set based on the IPv4 address to generate the IPv6 address of the interface identifier, extracting The IPv4 addresses embedded in the obtained IPv6 addresses are screened, and the geographic location information of the extracted IPv4 addresses is determined, and a first IPv6 address-geographic location information mapping is established.

作为一种实施方式，分析IPv6地址的接口标识中嵌入IPv4地址的特征，建立第一IPv6地址-地理位置信息映射，可以具体包括：As an implementation manner, analyzing the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address, and establishing the first IPv6 address-geographic location information mapping may specifically include:

获取IPv6地址集；Get IPv6 address set;

分析IPv6地址集中各IPv6地址的接口标识的生成方式；Analyze the generation method of the interface identification of each IPv6 address in the IPv6 address set;

筛选IPv6地址集中接口标识为基于IPv4地址编码的IPv6地址；Filter the interface in the IPv6 address set and identify it as an IPv6 address based on IPv4 address encoding;

提取筛选得到的各IPv6地址的接口标识中嵌入的IPv4地址；Extracting the IPv4 address embedded in the interface identifier of each IPv6 address obtained after screening;

基于IPv4地址地理位置库确定提取得到的各IPv4地址的地理位置信息，建立第一IPv6地址-地理位置信息映射。The extracted geographic location information of each IPv4 address is determined based on the IPv4 address geographic location database, and a first IPv6 address-geographic location information mapping is established.

本公开中，可以从包含IPv6地址的公开数据源中抽取IPv6地址形成IPv6地址集。获取IPv6地址集后，可以根据其中各IPv6地址的接口标识的特点分析出接口标识的构成模式，判断各IPv6的接口标识是否是基于IPv4地址编码生成。In the present disclosure, IPv6 addresses may be extracted from public data sources containing IPv6 addresses to form an IPv6 address set. After the IPv6 address set is obtained, the composition mode of the interface identifier can be analyzed according to the characteristics of the interface identifier of each IPv6 address, and it can be judged whether each IPv6 interface identifier is generated based on the IPv4 address code.

图3为本公开实施例提供的第一IPv6地址-地理位置信息映射的建立过程示例图；如图3所示，首先收集现有公开的IPv6地址形成IPv6地址集，然后分析各IPv6地址的IID的生成方法，提取基于IPv4地址编码生成IID的IPv6地址，然后提取IID中嵌入的IPv4地址，查询IPv4地址地理位置库确定提取到的各IPv4地址的地理位置信息，形成第一IPv6地址-地理位置信息映射。Fig. 3 is an example diagram of the establishment process of the first IPv6 address-geographic location information mapping provided by the embodiment of the present disclosure; as shown in Fig. 3 , first collect the existing public IPv6 addresses to form an IPv6 address set, and then analyze the IID of each IPv6 address The generating method is to extract the IPv6 address based on the IPv4 address encoding to generate the IID, then extract the IPv4 address embedded in the IID, query the IPv4 address geographic location database to determine the geographic location information of each IPv4 address extracted, and form the first IPv6 address-geographic location information mapping.

可以理解的是，通过分析IPv6地址的接口标识中嵌入的IPv4地址的特征建立IPv6地址-地理位置信息映射，丰富了IPv6地址地理位置库。It can be understood that the IPv6 address-geographic location information mapping is established by analyzing the characteristics of the IPv4 address embedded in the interface identifier of the IPv6 address, which enriches the IPv6 address geographic location library.

S13、基于位置语义分析获得IPv6地址反向域名解析字符串涵盖的地理位置信息，建立第二IPv6地址-地理位置信息映射。S13. Obtain geographic location information covered by the reverse domain name resolution string of the IPv6 address based on location semantic analysis, and establish a second IPv6 address-geographic location information mapping.

域名系统(DNS)是互联网不可分割的一部分。DNS域名解析服务是用于解析域名与IP地址对应关系的服务，功能上可以实现正向解析与反向解析。The Domain Name System (DNS) is an integral part of the Internet. DNS domain name resolution service is a service for resolving the corresponding relationship between domain names and IP addresses, which can realize forward and reverse resolution in function.

正向域名解析就是把域名指向网站所在服务器的IP，让人们通过注册的域名可以访问到网站。IP地址是网络上标识服务器的数字地址，为了方便记忆，使用域名来代替IP地址。域名解析就是域名到IP地址的转换过程，域名的解析工作由DNS服务器完成。DNS服务器会把域名解析到一个IP地址，然后在此IP地址的主机上将一个子目录与域名绑定。域名解析时会添加解析记录，这些记录有：A记录、AAAA记录、CNAME记录、MX记录、NS记录、TXT记录、SRV记录、URL转发。其中A记录将域名指向一个IPv4地址，AAAA记录将域名指向一个IPv6地址。Forward domain name resolution is to point the domain name to the IP of the server where the website is located, so that people can access the website through the registered domain name. An IP address is a numerical address that identifies a server on the network. For the convenience of memory, a domain name is used instead of an IP address. Domain name resolution is the conversion process of domain name to IP address, and the resolution of domain name is completed by DNS server. The DNS server will resolve the domain name to an IP address, and then bind a subdirectory to the domain name on the host at this IP address. Resolution records will be added during domain name resolution. These records include: A record, AAAA record, CNAME record, MX record, NS record, TXT record, SRV record, and URL forwarding. The A record points the domain name to an IPv4 address, and the AAAA record points the domain name to an IPv6 address.

反向域名解析(Reverse DNS，简称rDNS)，负责解析IPv4或IPv6地址对应的主机名。rDNS通过查询IP地址的PTR记录来得到该IP地址指向的域名。DNS PTR记录，也称为指针记录或反向DNS记录，是用于存储与IP地址关联的域名或主机名，DNS PTR记录将主机名或域名与IP地址连接起来。Reverse domain name resolution (Reverse DNS, referred to as rDNS), is responsible for resolving the host name corresponding to the IPv4 or IPv6 address. rDNS obtains the domain name pointed to by the IP address by querying the PTR record of the IP address. DNS PTR records, also known as pointer records or reverse DNS records, are used to store domain names or host names associated with IP addresses, and DNS PTR records connect host names or domain names with IP addresses.

反向域名解析的主机名通常用于命名和描述组成互联网的底层物理基础设施，可以从rDNS主机名中提取主机所在的城市、州、国家等地理位置信息以及物理连接特性信息等等。例如：主机名adsl-42.wallingford.ct.bigisp.us中Wallingford对应沃林福德镇，ct对应Connecticut康涅狄格州，us对应美国。The hostname of reverse domain name resolution is usually used to name and describe the underlying physical infrastructure that makes up the Internet. From the rDNS hostname, the geographical location information such as the city, state, and country where the host is located, as well as physical connection characteristics information, etc. can be extracted. For example: in the host name adsl-42.wallingford.ct.bigisp.us, Wallingford corresponds to Wallingford, ct corresponds to Connecticut, and us corresponds to the United States.

在实际应用中，可以基于对IP地址的反向域名解析得到该IP地址对应的地理位置信息；则，在一些可能的实施方式中，基于位置语义分析获得IPv6地址反向域名解析字符串涵盖的地理位置信息，建立第二IPv6地址-地理位置信息映射，可以包括：探测IPv6地址集中各IPv6地址的路由路径，并将探测到的各路由路径中的每跳IPv6地址汇总去重后进行反向域名解析得到其对应的主机名字符串，确定解析得到的各主机名字符串的位置信息，建立第二IPv6地址-地理位置信息映射。In practical applications, the geographical location information corresponding to the IP address can be obtained based on the reverse domain name resolution of the IP address; then, in some possible implementations, the IPv6 address reverse domain name resolution string covered by the Geographic location information, establishing a second IPv6 address-geographic location information mapping, may include: detecting the routing path of each IPv6 address in the IPv6 address set, and summarizing and deduplicating each hop IPv6 address in each detected routing path before reverse The domain name analysis obtains its corresponding host name string, determines the location information of each host name string obtained through analysis, and establishes a second IPv6 address-geographic location information mapping.

本公开中，首先获得包含多个IPv6地址的IPv6地址集，然后通过对各IPv6地址进行路由路径探测得到多条路由路径；在实际应中，由于每条路由路径中可能包括除IPv6地址集中含有的IPv6地址之外的其他多跳IPv6地址，则通过对各路由路径进行探测分别可以得到多跳IPv6地址。并且，通过探测每条路由路径所得到的IPv6地址中可能有重复，则需要将获得的所有跳IPv6地址汇总去重。In this disclosure, first obtain the IPv6 address set containing multiple IPv6 addresses, and then obtain multiple routing paths by performing routing path detection on each IPv6 address; If there are other multi-hop IPv6 addresses other than the specified IPv6 address, the multi-hop IPv6 addresses can be obtained respectively by detecting each routing path.
