Managing Record Sets in Batches

Overview

DNS provides the batch operation function to facilitate efficiency in managing record sets.

It provides the following functions:

• Adding Record Sets to Multiple Public Zones: Add record sets of the same type for multiple zones and subdomains in batches in the same resolution line.
• Deleting Record Sets from Multiple Public Zones: Delete record sets with a specific name from multiple zones.
• Modifying Record Sets: Batch modify the names and values of record sets.
• Exporting Record Sets: Batch export all record sets of in a single zone.
• Importing Record Sets: Batch import record sets for a single zone.

Adding Record Sets to Multiple Public Zones

Scenario

DNS allows you to perform batch operations on record sets. You can add record sets of the same type for multiple zones and subdomains in batches in the same resolution line.

Table 1 provides some examples to describe how to add record sets for multiple domain names.

Constraints

• You can only add record sets to public zones in batches.
• Before you add record sets, you must have created public zones by following the instructions in Creating a Public Zone, or the added record sets will not take effect.
• When you add record sets, note the following:
  • You can add record sets to up to 10,000 public zones at a time.
  • Up to 10 record sets can be added to each zone (including the subdomains).
  • The record set name is the same for each zone.
  • The line type is set to Default.
  • The TTL is set to 300s by default.

Procedure

1. Go to the Public Zones page.
2. Select the zones to which you want to add record sets and select Add Record Sets from the Batch Operations drop-down list.
3. On the Add Record Sets page, configure the parameters based on Table 1.
   • Domain Name: domain names that you want to configure record sets for.
     

     • You do not need to set this parameter since you have already selected the zones in 2.
     • If you click Add Record Sets without selecting any zones, enter the domain names, with each on a separate line.
   • Type: type of record set to be added
   • Record Set Name: prefix for the domain names
   • Value: value of the record sets
4. Click Submit.

   After the operation is complete, you can view the operation name, result, time, and status on the View Batch Operations tab. You can also download failed operations.

Deleting Record Sets from Multiple Public Zones

Scenario

You can delete record sets with a specific name from multiple zones in batches.

Deleted record sets cannot be recovered, and domain name queries will fail. Exercise caution when performing this operation.

Table 2 provides some examples to describe how to delete record sets from multiple zones.

Constraints

• Only record sets added to public zones can be deleted in batches.
• SOA and NS record sets are automatically generated and cannot be deleted.
• If specified record sets do not exist for a domain name, these record sets will not be deleted.
• When deleting record sets, note the following:
  • You can delete record sets from no more than 10,000 domain names at a time.
  • Up to five record set names can be modified at a time.

Procedure

1. Go to the Public Zones page.
2. Select the zones from which you want to delete record sets, and select Delete Record Sets from the Batch Operations drop-down list.
3. On the Delete Record Sets page, configure the parameters based on Table 1.
   • Domain Name: domain names whose record sets you want to delete
     

     • You do not need to set this parameter since you have already selected the zones in 2.
     • If you click Delete Record Sets without selecting any zones, enter the domain names, with each on a separate line.
   • Deletion Condition: Delete record sets meeting any of the conditions is selected by default.

     Currently, Record set name is the only deletion condition.

4. Click Submit.

   After the operation is complete, you can view the operation name, result, time, and status on the View Batch Operations tab. You can also download failed operations.

Modifying Record Sets

Scenario

You can modify the name or value of the record sets configured for multiple domain names in batches.

Constraints

• Only record sets added to public zones can be modified in batches.
• Only A record sets can be modified.
• Either the name or value of the record sets can be modified. They cannot be modified at the same time.
• When modifying record sets, note the following:
  • You can modify record sets to no more than 10,000 domain names at a time.
  • Up to five record set names can be modified at a time.
  • Up to 50 unique record set values are allowed.

Procedure

1. Go to the Public Zones page.
2. In the public zone list, select the zone whose record sets are to be modified.
3. In the upper part of the public zone list, choose Batch Operations > Modify Record Sets.
4. On the displayed page, configure the parameters as prompted.
   • Domain Name: The selected domain names are displayed by default. You can also enter the domain names. Enter each domain name on a separate line. Up to 10,000 domain names can be entered.
   • Record set name: Enter the new name for the record sets. You can enter up to five record set names. Each time you enter a record set name and press Enter.
   • Record sets that meet any of the conditions: Modify the record set name or value.
     • Change record set name to: Enter a new record set name. If you select this option, you cannot configure new record set values.
     • Change record set value to: Enter a new IP address on each line. You can enter up to 50 different IP addresses. If you select this option, you cannot need to configure new record names.

   

5. Click Submit.

   After the operation is complete, you can view the operation name, result, time, and status on the View Batch Operations tab. You can also download failed operations.

Exporting Record Sets

Scenario

If you want to transfer your domain name to another cloud service provider, you can export all the record sets configured for the domain name in batches.

You can export the following information about a public zone record set: record set name, record set type, line type, TTL (s), weight, record set value, status, description, record set ID, time when the record set was created, and time when the record set was last modified.

Procedure

1. Go to the Public Zones page.
2. In the public zone list, click the name of the public zone whose record sets are to be exported.
3. Click the Export and Import tab.
4. Click Export Record Set in the upper right corner of the page.

   An .xlsx file named using the domain name is exported, for example, example.com.xlsx.

   In the exported file, you can view the following information about a record set: record set name, record set type, line type, TTL (s), weight, record set value, status, description, record set ID, time when the record set was created, and time when the record set was last modified.

Importing Record Sets

Scenario

If you want to transfer your domain name from another cloud server provider to the DNS service for hosting, you can import existing record sets configured for the domain name in batches.

You can import up to 500 record sets at a time.

Before importing record sets, you have created public zones on the DNS console. For details, see Creating a Public Zone.
