It should be noted that the recursive server home location positioning method and apparatus disclosed in the present disclosure may be used in the field of big data technology, may also be used in the financial field, and may also be used in any field other than the field of big data technology and the financial field.

A Local DNS server (recursive server) carries a first service for a user to access a domain name, and recurses a DNS request (a request for domain name resolution, that is, a domain name resolution is a corresponding IP address) of the user to an authoritative server through the Local DNS server, which plays an important role in intelligent scheduling of network traffic and intelligent service of the internet.

In the related art, the home location of the Local DNS is generally determined by an IP positioning method, which is complex to implement and inefficient in processing. Meanwhile, the positioning methods in the related art are all based on the same design logic, and the positioning accuracy needs to be improved, so that if a new positioning mode can be designed, the positioning method can be used or verified in a cross mode with the positioning method in the related art, and the accuracy of recursive server geographic positioning can be improved.

In view of the above, embodiments of the present disclosure provide a new recursive server home location method.

Fig. 2 schematically shows a flow chart of a recursive server home location method according to an embodiment of the present disclosure.

As shown in fig. 2, the method includes operations S201 to S203.

In operation S201, a target domain name is obtained, wherein the target domain name is a registered domain name associated with an organization to which the recursive server belongs.

In operation S202, the target domain name is analyzed to obtain first positioning information and second positioning information, where the first positioning information is used to represent region and type information of an organization to which the recursive server belongs, and the second positioning information is used to represent registration information of the organization to which the recursive server belongs.

In operation S203, a home of the recursive server is located according to the first location information and the second location information.

According to an embodiment of the present disclosure, the target domain name is a registered domain name related to an organization to which the recursive server (Local DNS server) belongs, and may be, for example, a registered domain name of a network operator to which the Local DNS server belongs. Further, the target domain name may be a domain name corresponding to an IP address of the Local DNS server.

The positioning method provided by the embodiment of the disclosure has the design idea that the location information of the organization to which the Local DNS server belongs is acquired by analyzing the registration domain name of the organization to which the Local DNS server belongs, and the geographical location of the organization to which the Local DNS server belongs is determined as the geographical location of the Local DNS server under reasonable inference since the data center address of the Local DNS server is presumed to be located near the organization to which the Local DNS server belongs.

Therefore, according to the embodiment of the present disclosure, a target domain name for characterizing a domain name registered by an organization to which a Local DNS server belongs needs to be obtained first; furthermore, the first positioning information and the second positioning information are obtained by analyzing the target domain name. Thereafter, a home location of the recursive server may be located based on the first positioning information and the second positioning information.

The first positioning information is used for representing the region and type information of the organization to which the recursive server belongs. According to the embodiment of the disclosure, the region and type information is used for preliminarily judging the geographical location of the organization to which the Local DNS server belongs, for example, it can be preliminarily determined that the organization may belong to a country, for example, it can be preliminarily presumed that the organization belongs to china, japan, usa, or the like, but it cannot be determined what specific geographical location of the country the organization is located; the regional and type information may also preliminarily determine what type of organization the organization is, such as perhaps an industrial business, a network operator, or a non-profit organization, among others.

The second positioning information is used for representing registration information of an organization to which the recursive server belongs, the registration information is used for representing detailed basic information of the organization, and some basic registration information of the organization is represented, such as more specific information that may include a company address, a mailbox, a contact telephone and the like of the organization. Through the second positioning information, more specific geographical location information of the organization can be determined, and further, the specific geographical location of the Local DNS server can be inferred, for example, a certain downtown of a certain city in a certain country.

According to the embodiment of the disclosure, the first positioning information and the second positioning information can be acquired by acquiring the target domain name and analyzing the target domain name. According to the embodiment of the disclosure, by adopting a technical means of analyzing the target domain name to obtain the positioning information, the positioning information is obtained more directly and quickly, and has more pertinence, and the efficiency of positioning analysis can be improved. The region and organization type of the organization to which the recursion server belongs are preliminarily judged through the first positioning information, and more detailed positioning information is obtained from the registration information of the organization to which the recursion server belongs, which is provided by the second positioning information. The embodiment of the disclosure combines the two positioning information to estimate the attribution of the recursive server, and the positioning is more accurate due to the combination of the two positioning information. Further, the embodiment of the present disclosure provides a new recursive server home location method, which can be used or cross-verified with a location method (such as an IP location method) in the related art, so as to improve the accuracy of recursive server geolocation. By determining the address of the recursive server (Local DNS) by adopting the positioning method, the validity of the address library of the recursive server (Local DNS) can be checked, the address library of the recursive server (Local DNS) can be updated regularly, and reference and comparison are provided for the determination of the Local DNS address of a subsequent network operator.

According to an embodiment of the present disclosure, the region and type information includes at least one of the following: home country information of an organization to which the recursive server belongs (for example, the organization belongs to china, japan, or the united states, etc.), and organization type information of the organization to which the recursive server belongs (for example, the organization may be a business enterprise, a network operator, or a non-profit organization, etc.); the registration information includes at least one of: the registration address, contact mailbox, contact phone, and remark information of the organization to which the recursive server belongs, the remark information being the information remarked when the organization registers, which may include any information helpful for obtaining the geographical location of the organization.

It should be noted that the region and type information and the registration information in the embodiments of the present disclosure include, but are not limited to, the above listed types, and the specific types are determined according to the basic information provided by the organization at the time of registration, and therefore, the above two types of information may also include any other types of information.

Fig. 3 schematically illustrates a flowchart for acquiring first positioning information and second positioning information according to an embodiment of the disclosure. According to an embodiment of the present disclosure, the target domain name includes a primary domain name and a secondary domain name.

As shown in fig. 3, the method includes operations S301 to S302.

In operation S301, a first-level domain name in the target domain name is resolved to obtain first positioning information.

In operation S302, a secondary domain name in the target domain name is resolved to obtain second positioning information.

According to the embodiment of the disclosure, the domain name is composed of two or more groups of ASCII or language characters of each country, the characters of each group are separated by dot numbers, the rightmost character group is called a top-level domain name or a first-level domain name, the second last group is called a second-level domain name, the third last group is called a third-level domain name, and the like.

The first-level domain names are divided into three categories: firstly, top-level domain names (called ccTLDs [1]) of countries and regions, top-level domain names are distributed to more than 200 countries according to ISO3166 country codes, for example, China is cn, Japan is jp, etc.; the second is a general top-level domain name (gTLDs), such as com, which represents an industrial and commercial enterprise, net, which represents a network provider, org, which represents a non-profit organization, and so on. Third, New top-level domain names (New gTLD) such as universal. xyz, top for "high end", red for "red", men for "person", etc. are more than one thousand.

In operation S301, first positioning information used for representing the region and type information of the organization to which the recursive server belongs may be obtained by analyzing the first-level domain name in the target domain name. If the domain name is generated with a typical national meaning, such as xxx. cn, it can be reasonably inferred that the domain name belongs to china, which means that the local DNS address belongs to china, and so on for other first-level domain names with national meaning, such as jp, hk, etc. Or the type information of the organization mechanism of the organization to which the server belongs can be judged by analyzing the first-level domain name (for example, the organization may be an industrial enterprise, a network operator, or a non-profit organization); net, for example, the organization may be inferred to be a network operator, and the organization type information may not be directly related to the geographical location information of the organization, but may be used as auxiliary information to help infer its geographical location.

The significance of Second Level Domain names (SLDs) is different under international top Level Domain names or national top Level Domain names.

The second-level domain name under the international top-level domain name generally refers to a network name selected by a domain name registrant to use, such as 'yahoo.com'; a business organization surfing the internet typically uses its own trademark, business number or other commercial designation as its own web name, such as "microsoft.

The second level domain name under the national top level domain name generally refers to a label representing registrant category and function similar to the international top level domain name. Cn "domain name structure,". com "is now a secondary domain name placed under the country top domain name". cn "representing a commercial organization, and so on.

In the above operation S302, the second positioning information for characterizing the registration information of the organization to which the recursive server belongs is obtained by resolving the second level domain name in the target domain name. The registration information is used to characterize the detailed basic information of the organization, including some basic registration information of the organization, such as the registration address, contact mailbox, contact telephone, and remark information of the organization to which the recursive server belongs, wherein the remark information is the remark information when the organization registers, and may include any information helpful for acquiring the geographic location of the organization.

Through the second positioning information, more specific geographical location information of the organization can be determined, and further, the specific geographical location of the Local DNS server can be inferred, for example, a certain downtown of a certain city in a certain country.

According to the embodiment of the disclosure, the positioning information is acquired by a technical means of analyzing the first-level domain name and the second-level domain name in the target domain name, the acquisition of the positioning information is more direct and faster, the positioning information is more targeted, and the positioning and analyzing efficiency can be improved.

Specifically, the embodiment of the present disclosure provides a specific method for resolving a secondary domain name in a target domain name to obtain second positioning information in the above operation. Fig. 4 schematically illustrates a flowchart of resolving a secondary domain name to obtain second positioning information according to an embodiment of the present disclosure.

As shown in fig. 4, the above method includes operations S401 to S402 according to an embodiment of the present disclosure.

In operation S401, the secondary domain name is resolved to obtain one or more target registration addresses, where the target registration addresses are registration addresses of the target domain name.

In operation S402, second positioning information is acquired by accessing the target registration address.

Specifically, according to an embodiment of the present disclosure, in operation S401, resolving the secondary domain name to obtain one or more target registration addresses includes: querying record information related to the secondary domain name through an RDAP protocol; and acquiring one or more target registration addresses corresponding to the target domain name from the recorded information.

Icann (the Internet Corporation for Assigned Names and numbers) Internet name and number assignment mechanism is a non-profit international organization, which is a non-profit international organization gathering experts in all fields of commerce, technology and academia of the world network, and is responsible for coordinating the Internet unique identifier system and its safe and stable operation globally, including space allocation of Internet Protocol (IP) addresses, assignment of protocol identifiers, management of generic top-level domain Names (gTLD) and national and regional top-level domain Names (ccTLD) systems, and management of root server systems. These services were originally provided by the Internet Assigned Number Authority (IANA) under U.S. government contracts, as well as by some other organization. ICANN functions as IANA.

The RDAP protocol is a new standard protocol popularized in 2019 by ICANN International organization for trial and error in 2018. By which recorded information related to a specified secondary domain name (e.g., the secondary domain name: bloomberg.com. of domain name iny-spdrproxy2. bloomberg.com.) can be queried and from which one or more target registration addresses corresponding to the domain name are obtained.

By resolving the domain name, the registration address from which the registration domain name is obtained may include one or more of, for example, address 1, address 2, address … …, address n.

For example, the secondary domain name is derived by the RDAP protocol: com has the following two target registration addresses:

https：∨∨rdap.verisign.com∨com∨v1∨domain∨BLOOMBERG.COM；

https：∨∨apis.cscglobal.com∨dbs∨rdap-api∨v1∨domain∨BLOOMBERG.COM；

if the number of the address connections obtained by the RDAP protocol is more than one, the registration information representing the domain name is registered at the two addresses, and the user can access the one or more registration addresses (address 1, address 2, address … … n) through the terminal device, and obtain the query result of the registration information representing the organization to which the recursive server belongs from the corresponding server (or database). After the registration information is acquired, the home information of the Local DNS server (recursive server) is acquired by analyzing and processing the registration information.

By adopting the method of the embodiment of the disclosure, the target domain name needs to be acquired first, and the method for acquiring the target domain name includes but is not limited to: and acquiring the target domain name according to the IP address of the recursive server.

Specifically, the operation of obtaining the target domain name according to the IP address of the recursive server specifically comprises: the IP address of the recursive server is resolved to the target domain name by means of reverse address resolution.

That is, the user can resolve the IP address of the Local DNS server into a registered domain name organized with the home of the recursive server by performing a reverse resolution task on the terminal device according to the known IP address of the Local DNS server.

According to an embodiment of the present disclosure, domain name information for reverse domain name resolution of a local DNS address can be queried from a PTR record (pointer record) of a DNS by using a DNS query tool, such as a dig or nslookup tool.

According to the embodiment of the present disclosure, the foregoing recursive server home location method is exemplarily described in detail as follows:

(1) first, a target domain name is obtained, specifically, domain name information of reverse domain name resolution is queried from a PTR record (pointer record) of a DNS to a local DNS address using a dig tool

Example (c): taking the IP address 69.191.211.202 of local DNS as an example, the result of executing the query task is as follows:

<<>>DiG 9.10.6<<>>-x 69.191.211.202

Global options：+cmd

Got answer：

->>HEADER<<-opcode：QUERY，status：NOERROR，id：56235

flags：qr rd ra；QUERY：1，ANSWER：1，AUTHORITY：0，ADDITIONAL：0

QUESTION SECTION：

MSG SIZE rcvd：87

from the above query results, it can be seen that the answer to the DNS resolution query request is: iny-spdrproxy2 bloomberg.com, that is, the name of the target domain is obtained by reversely resolving the IP address of the recursive server: iny-spdrproxy2 bloomberg.

(2) After the target domain name is obtained, the target domain name is analyzed, and first positioning information and second positioning information are obtained.

The first-level domain name for this domain name: ". com", which can be used as auxiliary information to help infer its geographical location, although the organization type information has no direct relation with the geographical location information of the organization.

For the second level domain name of the domain name: com, the second-level domain name is obtained through an RDAP protocol, and the specific execution result is as follows:

according to the query result, it can be seen that, for the domain name: com has two target registration addresses:

https：∨∨rdap.verisign.com∨com∨v1∨domain∨BLOOMBERG.COM；

https：∨∨apis.cscglobal.com∨dbs∨rdap-api∨vl∨domain∨BLOOMBERG.COM；

that is, the registration information of the secondary domain name can be queried through both the two links, and it is possible that the information contents provided by the two links are different, and if the information contents are different, the two query results are obtained.

In the following, only one of the links is accessed to obtain the second positioning information for example.

Accessing the link according to the method provided by ICANN: https: com/com/v1/domain/bloomberg.com
