Definitions
- the present invention relates to the field of computer networks, and in particular, to a method and system for domain name resolution. Background technique
- Domain Name is the name of a computer or group of computers on the Internet consisting of a series of dot-separated names. It is used to identify the computer's electronic orientation (sometimes referred to as geographic location) during data transmission.
- Traditional Domain name each domain name is a separate entity, with contacts, domain name servers and other information; the domain name has become one of the Internet brand and one of the necessary products for online trademark protection.
- a domain name group mainly refers to a domain name group consisting of one or more domain names.
- the domain name shares the basic information such as the registrant and the contact person, and can be registered at the same time or added later. Modify the information shared by the domain name group, and share the information of all domain names. Simultaneous modification;
- the domain name group provides a convenience for managing multiple domain names, allowing registrants to register multiple domain names while sharing the registrant information and contact information, which facilitates the management of domain names by end users and registries. operating.
- DNS Domain Name System
- IDN domain names are quite different from traditional domain names.
- Chinese characters are varied in variety, such as simple, complex, and variant, and the application is more complicated. Take Chinese characters as an example: the simplified form of the word “back” is “back”, and the traditional form is “back”. In addition to this, there are variants such as "same, back, ⁇ , ⁇ , back”.
- the organization that supports IDN domain name registration management supports the registration of an IDN domain name.
- the registrant can activate the simplified, traditional and variant domain name corresponding to the domain name, so that it becomes a domain name group, and these domain names share some Registration information, so the DNS resolution of this domain name group needs to be implemented.
- the present invention provides a method and system for supporting "domain name group” DNS resolution, which can implement domain name resolution in a "domain name group”.
- the system of the present invention includes a registration data storage device, a resolution generation server, and a DNS resolution server.
- the method of the invention comprises the following steps:
- the parsing generation server reads the domain name data information of the domain name group from the registered data storage device
- the parsing and generating server determines whether the domain name in the domain name group shares the domain name server or has a canonical domain name; (3) parsing the generation server to configure or parse the corresponding parsing record for the domain name, and record;
- Step (3) includes:
- the NS record is configured for each domain name according to the user, and is recorded in the parsing file;
- the canonical domain name is set to resolve the NS record, and other domain names in the group pass the CNAME record or DNAME to the domain name;
- Step d) When the domain name in the domain name group does not have a canonical domain name, set a domain name as the canonical domain name, and then proceed to step c). Step d) Set the canonical domain name by the registry or the domain name system.
- the present invention implements a group parsing method by adding several resource records of domain names in a domain name group, and can implement flexible configuration.
- This method implements the resolution of the domain name group by implementing the configuration NS record (domain name resolution server resource record), the domain name CNAME record, and the domain name DNAME record.
- NS record domain name resolution server resource record
- domain name CNAME record domain name CNAME record
- domain name DNAME record domain name DNAME record
- FIG. 1 is a device deployment and data flow diagram of the present invention
- FIG. 2 is a logic block diagram of three methods for supporting "domain name group” DNS resolution of the present invention
- Figure 3 is a resolution diagram of a domain name group by setting a domain name server
- Figure 4 is a resolution map of the domain name group by setting a CNAME record
- Figure 5 is a resolution map of the domain name group by setting a DNAME record
- FIG. 6 is a diagram of an embodiment of the present invention. detailed description
- the device deployment and data flow of the present invention is as shown in FIG. 1.
- the registration data storage device stores the domain name group data information.
- the parsing generation server generates the parsed data by reading the domain name group data information in the registration data storage device, and sends the parsed data to the DNS.
- the present invention provides three schemes for parsing a domain name group by configuring an NS record, configuring a CNAME record, and configuring a DNAME record, as shown in FIG. 2 .
- the invention passes The domain name group data information is read, and the "domain name group" DNS resolution is supported.
- Embodiment 1 Embodiment 1
- the resolution generation server reads the domain name group information from the registration data storage device and the resolution server data of the domain name group; according to the user setting, or according to the policy managed by the registration authority, the domain name resolution server is shared or the domain name server data is respectively set for each domain name of the domain name group.
- the specific steps are shown in Figure 3:
- the parsing and generating server reads the domain name data, generates a "representative domain name" of the domain name according to the supporting word table of the registered domain name, and obtains all the data of the domain name group by the representative domain name.
- the representative word of "real, real, defamatory; real” is the last "real", the representative of the "national, national, garden; country” character group is the last "country”, so the " ⁇ . ⁇ ” domain name
- the representative domain name is "Real Country. China”.
- the representative character of a character group can be the character whose Unicode is the smallest character, or the character specified by the registrar such as Simplified or Traditional.
- the analytic generation server analyzing the private domain name data, according to different suffixes of the domain name, the analytic generation server generates NS records of each domain name respectively, writes them into different parsing files, and sends them to the DNS resolution server for parsing; in FIG. 6,
- the domain names "instance. China” and "instance. China” all generate the same NS record when they have a shared domain name server: NSl.host.tld; and when the two domain names have different two domain name servers, two are generated.
- Different NS records NSl.host.tldl and NSl.host.tld2.
- the resolution generation server reads the domain name group information from the registration data storage device; analyzes and determines whether the user has one or more domain names as the canonical domain name, or according to the registration policy, specifies one or more domain names in the domain name group as the canonical domain name
- the parsing record of the canonical domain name is generated to the DNS resolution server, and the other domain name (non-canonical domain name) is recorded to the specified canonical domain name by the CNAME, and the parsing record of the specified domain name is generated to the DNS resolution server, and the parsing is performed, and the specific steps are as follows: 4 shows:
- the representative character of a character group can be the character whose Unicode is the smallest character, or the character specified by the registrar such as Simplified or Traditional.
- the analytic generation server generates an NS record for the domain name of the domain name group, and generates NS records according to different suffixes, and sends them to different DNS files for parsing.
- the other domain names in the group are different according to the suffix. Go to the canonical domain name, and generate it into different parsing files according to the suffix, and send it to the DNS resolution server for resolution; (for example, two domain names in a domain name group: "1.", “l.cn", its suffix For "China” and “cn” respectively, the parsing records will be generated into different parsing files according to the suffix, "1.” is generated to the "China.zone” file; "l.cn” is generated to "cn.” Zone” in the file.)
- Analyze the generation server according to the support word table of the registered domain name, generate the "recommended domain name" of the domain name (usually set by the registry or the domain name system), for example: “real, real, ⁇ "; the recommended word is “real”
- the recommended word for the "Country, Country, Garden” character group is "Country”, so the recommended domain name for the "Yuguo. China” domain name is "Real Country. China”.
- the analytic generation server generates an NS record for the recommended domain name in the domain name group, and generates the NS record according to the suffix, and sends it to the DNS resolution server for resolution.
- the other domain names in the group are recorded by the CNAME according to the suffix. Generated into a different parsing file, sent to the DNS resolution server for parsing.
- the registration authority When the domain name group consisting of the domain name "instance. China” and “instance. China” does not have the canonical domain name, the registration authority first configures a recommended domain name "instance. China” in the region, and then resolves the generated server to "instance". China's “harmony” Example. Example of "Recommended Domain Name in a Domain Name Group Composed” in China. China “Generates NS Records:
- the other domain name "Instance. China” records the recommended domain name "Instance. China” through CNAME, and generates the corresponding resolution record as:
- the parsing and generating server reads the domain name group information from the registered data storage device; analyzes and determines whether the user sets one or more domain names as the canonical domain name, or according to the registration policy, specifies one or more domain names in the domain name group as the canonical domain name, Generate the resolution record of the canonical domain name to the DNS resolution server. Other domain names are recorded to the domain name through DNAME, and generated into the DNS resolution server for resolution. The specific steps are as shown in Figure 5:
- the representative character of a character group can be a character whose Unicode is the smallest character, or a character specified by a registrar such as Simplified or Traditional.
- the analytic generation server generates an NS record for the domain name group domain name domain domain, and generates NS records according to different suffixes, and sends them to different DNS resolution servers for parsing.
- the other domain names in the group are recorded by DNAME according to different suffixes.
- the domain name is generated into a different parsing file and sent to the DNS resolution server for parsing;
- Analyze the generation server according to the support word list of the registered domain name, generate the "recommended domain name" of the domain name, for example: “real, real, ⁇ "; the recommended word is “real", “national, national, garden” character group
- the recommended word is "country”, so the recommended domain name for the "Yuguo. China” domain name is "Real Country. China”.
- the analytic generation server generates an NS record for the recommended domain name in the domain name group, and generates the NS record according to the suffix, and sends it to the DNS resolution server for resolution.
- the other domain names in the group are recorded by the DNAME according to the suffix. Generated to different solutions In the resolution file, it is sent to the DNS resolution server for resolution.
- the registration authority When the domain name group consisting of the domain name "instance. China” and “instance. China” does not have the canonical domain name, the registration authority first configures a recommended domain name "instance. China” in the region, and then resolves the generated server to "instance". .Chinese “and” examples. Examples of "recommended domain names in domain groups formed by China”. China “Generate NS records:
- the other domain name "Instance. China” records the recommended domain name "Instance. China” through DNAME, and generates the corresponding resolution record as:
