Description

A configuration and query method for domain name sharing management authority

technical field

The invention relates to the field of network information technology, in particular to a method for configuring and querying domain name sharing management rights.

Background technique

According to the current DNS technical protocol, DNS cannot configure and query domain name management authority information. Usually users or clients with such needs will query through a world-renowned website (https://publicsuffix.org/list/public_suffix_list.dat). This site is maintained solely by volunteers of a well-known company, which does not facilitate the updating of information. Aiming at the weakness of centralized management, the experts from Dyn proposed the SOPA solution. This method has a good effect on any two domain names, but for the case of more than two domain names, the complexity of configuration and resolution will increase sharply. high question.

Contents of the invention

The purpose of the present invention is to provide a method for configuring and inquiring domain name sharing management authority, which is convenient for users to configure and inquire about multiple domain name sharing management authority information.

For above-mentioned purpose, the technical scheme that the present invention adopts is:

A method for configuring domain name sharing management authority, the steps comprising:

1) Establish the RDATA structure of the DNS Boundary resource record for each domain name in the domain name group to be configured with shared management authority, and the RDATA structure includes Flag and Pointer/Name-group fields;

2) Set an intermediate domain name;

3) Point each domain name in the above domain name group to the intermediate domain name through the DNS Boundary resource record;

4) The intermediate domain name points to each domain name in the domain name group to be configured with shared management authority through the DNS Boundary resource record.

Further, the domain name group includes any at least two domain names to be configured with shared management rights.

Further, the Flag field identifies the usage of Pointer/Name-group.

Furthermore, when Flag=0, the Pointer/Name-group stores the intermediate domain name pointed to by the domain name; when Flag=1, the Pointer/Name-group stores the domain name group pointed to by the domain name.

Further, the RDATA structure also includes a Reserved field, which will be used when new functions are added in the future.

Further, the intermediate domain name is a domain name in the domain name group whose shared management authority is to be configured or a domain name outside the domain name group; if the intermediate domain name is a domain name outside the domain name group whose shared management authority is to be configured, an The RDATA structure of the above DNS Boundary resource record.

A query method for domain name sharing management authority, the steps comprising:

1) Query DNS Boundary resource records for each domain name in the domain name group to be queried for shared management authority;

2) If the DNS Boundary resource records of each domain name in the domain name group point to the same intermediate domain name, query the DNS Boundary resource records of the intermediate domain name;

3) If the domain name group information pointed to by the DNS Boundary resource record of the intermediate domain name includes each domain name in the domain name group whose shared management authority is to be queried, then each domain name in the domain name group to be queried from the shared management authority shares the domain name Administrative rights.

Further, the domain name group includes any at least two domain names to be queried for sharing management authority.

Further, the intermediate domain name refers to the same domain name pointed to by the DNS Boundary resource records of each domain name in the domain name group.

Furthermore, the intermediate domain name is a domain name in the domain name group to be queried for sharing management authority or a domain name outside the domain name group.

The beneficial effects of the present invention are:

1) It is simpler to configure than existing methods;

The configuration of N domain names by the SOPA method requires a SOPA record configuration of C(N,2)=N*(N-1)/2 domain names; if N=10, the SOPA method needs 45 records to configure.

The method of the present invention only needs N+1 records to configure; said N+1 records mean: when the intermediate domain name is in the domain name group, each of the N domain names in the domain name group needs to point to the intermediate domain name, The intermediate domain name points to the domain name group composed of N domain names, so there are N+1 resource records in total; when the intermediate domain name is outside the domain name group, the N domain names in the domain name group have N records for the intermediate domain name, and the intermediate domain name has N records for the intermediate domain name The domain name group has 1 record, that is, a total of N+1 records are required. If N=10, the method of the present invention only needs 11 records for configuration.

2) It is simpler than the existing method query;

For whether N domain names share management rights, the SOPA method needs to query N*(N-1)/2 times.

As for whether N domain names share management authority, the method of the present invention only needs to inquire N+1 times.

3) It is convenient to handle the configuration and query of management authority information of multiple domain names;

The SOPA method is only efficient for the configuration and query of the management rights of two domain names. The method of the present invention can configure and query the shared management rights of multiple domain names, and can easily find out a group that has a shared management rights relationship with a certain domain name. domain name.

detailed description

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail in conjunction with the accompanying drawings.

The present invention provides a method for configuring and querying domain name shared management rights. The RDATA structure of the newly added DNS Boundary resource record for the domain name to be configured with shared management rights is shown in Figure 1, including Flag, Reserved and Pointer/Name-group three fields. Among them, the Reserved field will be used when new functions are added in the future, and the Flag field identifies the usage of Pointer/Name-group. When Flag is equal to 0, Pointer/Name-group stores the intermediate domain name (pointer) pointed to by the domain name; when Flag is equal to 1, Pointer/Name-group stores the domain name group (name-group) pointed to by the domain name.

The present invention provides a method for configuring domain name sharing management rights, the steps of which are as follows:

1) Establish the RDATA structure of the above-mentioned DNS Boundary resource record for any at least two domain names (which may be called a domain name group) to be configured with shared management authority;

2) Set a domain name as the intermediate domain name, the intermediate domain name can be the domain name in the domain name group whose shared management authority is to be configured, or a domain name outside the domain name group; if the intermediate domain name is the shared management authority to be configured For domain names other than the domain name group, the RDATA structure of the above-mentioned DNS Boundary resource records will be established for them;

3) Each domain name in the domain name group points to the intermediate domain name through the DNS Boundary resource record;

4) The intermediate domain name points to each domain name in the domain name group whose shared management authority information is to be configured through the DNS Boundary resource record; that is, the configuration of the domain name shared management authority is completed.

The present invention provides a query method for domain name sharing management authority, the steps of which are as follows:

1) Query the DNS Boundary resource records of each domain name in any at least two domain name groups to be queried for shared management authority;

2) If the DNS Boundary resource records of each domain name in the domain name group point to the same intermediate domain name, query the DNS Boundary resource records of the intermediate domain name, wherein the intermediate domain name refers to the DNS of each domain name in the domain name group Boundary resource records all point to the same domain name, and the intermediate domain name can be a domain name in the domain name group whose shared management authority is to be queried, or a domain name outside the domain name group;

3) If the domain name group information pointed to by the DNS Boundary resource record of the intermediate domain name includes each domain name in the domain name group whose shared management authority is to be queried, then each domain name in the domain name group to be queried from the shared management authority shares the domain name Administrative rights.

The present invention is explained below with two specific embodiments:

[Example 1] The intermediate domain name is one of the domain name groups to be configured with shared management rights.

If the four domain names A, B, C, and D want to configure shared management rights, they can be easily queried. The specific configuration process is as follows:

1. Create the RDATA structure of the DNS Boundary resource record for each domain name in the domain name group to be configured with shared management authority, that is, the domain name group is A, B, C, and D;

2. Set a domain name as the intermediate domain name, here domain name A is used as the intermediate domain name;

3. Point each domain name in the domain name group to the intermediate domain name through the DNS Boundary resource record, namely

A points to A through the DNS Boundary resource record;

B points to A through the DNS Boundary resource record;

C points to A through the DNS Boundary resource record;

D points to A through the DNS Boundary resource record;

4. The intermediate domain name points to all its domain name groups configured with shared management authority information through the DNS Boundary resource record, that is,

A points to A, B, C, and D through DNS Boundary resource records.

The above is the configuration process of domain name management rights, that is, domain names A, B, C, and D share management rights.

The process of how to determine that any at least two domain names (take two domain names as an example, such as domain name A and domain name B) have shared domain name management authority is as follows:

1. Query the DNS Boundary resource record of A;

When flag=0, A acts as an intermediate domain name, and A points to A through DNS Boundary resource records; when flag=1, A acts as a domain name in the domain name group, and A points to A, B, C, and D through Boundary resource records.

2. Query B's DNS Boundary resource record;

B points to A through the DNS Boundary resource record.

3. If the DNS Boundary resource records of A and B point to the same intermediate domain name, go to step 4, otherwise go to step 6;

The DNS Boundary resource records of A and B both point to the intermediate domain name A.

4. Find the DNS Boundary resource record of the intermediate domain name, and confirm whether the domain name group information it points to contains both A and B. If it contains A and B, it means that A and B share the same domain name management authority, then go to step 5, otherwise go to Step 6;

The DNS Boundary resource record of A as an intermediate domain name points to domain name groups A, B, C, and D, including two domain names A and B.

5. Return the information that A and B share domain name management rights, and exit;

Explain that A and B share domain name management authority information.

6. Return the information that A and B do not share domain name management authority, and exit.

[Example 2] The intermediate domain name is one outside the domain name group to be configured with shared management authority.

If the four domain names A, B, C, and D want to configure shared management rights, they can be easily queried. The specific configuration process is as follows:

1. Create the RDATA structure of the DNS Boundary resource record for each domain name in the domain name group to be configured with shared management authority, that is, the domain name group is A, B, C, and D;

2. Set a domain name as the intermediate domain name. Here, the domain name E is used as the intermediate domain name, and the RDATA structure of the above-mentioned DNSBoundary resource record is established for it;

3. Point each domain name in the domain name group to the intermediate domain name through the DNS Boundary resource record, namely

A points to E through the DNS Boundary resource record;

B points to E through the DNS Boundary resource record;

C points to E through the DNS Boundary resource record;

D points to E through the DNS Boundary resource record;

4. The intermediate domain name points to all its domain name groups configured with shared management authority information through the DNS Boundary resource record, that is,

E points to A, B, C, and D through DNS Boundary resource records.

The above is the configuration process of domain name management rights, that is, domain names A, B, C, and D share management rights.

The process of how to determine that any at least two domain names (take two domain names as an example, such as domain name A and domain name B) have shared domain name management authority is as follows:

1. Query the DNS Boundary resource record of A;

A points to E through the DNS Boundary resource record.

2. Query B's DNS Boundary resource record;

B points to E through the DNS Boundary resource record.

3. If the DNS Boundary resource records of A and B point to the same intermediate domain name, go to step 4, otherwise go to step 6;

Both the DNS Boundary resource records of A and B point to the intermediate domain name E.

4. Find the DNS Boundary resource record of the intermediate domain name, and confirm whether the domain name group information it points to contains both A and B. If it contains A and B, it means that A and B share the same domain name management authority, then go to step 5, otherwise go to Step 6;

The DNS Boundary resource record of E as an intermediate domain name points to domain name groups A, B, C, and D, including two domain names A and B.

5. Return the information that A and B share domain name management rights, and exit;

Explain that A and B share domain name management authority information.

6. Return the information that A and B do not share domain name management authority, and exit.
