Adding an AAAA Record Set

Scenarios

If you want end users to access your website, web application, or cloud server configured with an IPv6 address via its domain name, add an AAAA record set for this domain name.

For more information about each type of record sets, see Record Set Types and Configuration Rules.

Prerequisites

You have a web server and obtained an IPv6 address.

Procedure

1. Go to the DNS console.
2. In the navigation pane on the left, choose Public Zones or Private Zones.

   The zone list is displayed.

3. (Optional) If you have selected Private Zones, click on the upper left corner to select the region and project.
4. Locate the zone and click Manage Record Sets in the Operation column.
5. Click Add Record Set.

   The Add Record Set dialog box is displayed.

6. Configure the parameters based on Table 1.

   Table 1 Parameters for adding an AAAA record set

   Parameter	Description	Example Value
   Type	Type of the record set. A message may be displayed, indicating that the record set you are trying to add conflicts with an existing record set of the zone. For details, see Why Is a Message Indicating Conflict with an Existing Record Set Displayed When I Add a Record Set?	AAAA – Map domains to IPv6 addresses
   Name	Prefix of the domain name to be resolved. For example, if the domain name is example.com, the prefix can be as follows: www: The domain name is www.example.com, which is usually used for a website. Left blank: The domain name is example.com. To use an at sign (@) as the domain name prefix, just leave this parameter blank. abc: The domain name is abc.example.com, a subdomain of example.com. mail: The domain name is mail.example.com, which is usually used for email servers. *: The domain name is *.example.com, which is a wildcard domain name, indicating all subdomains of example.com.	www
   Line	Resolution line. The DNS server uses information about end users' carrier networks or geographical locations to determine the most appropriate server IP address to return. The default value is Default. This parameter is only configurable for public zone record sets. Default: returns the default resolution result when no resolution line is set based on end users' carrier networks or geographical locations. ISP: returns the resolution result based on end users' carrier networks. For details, see Configuring ISP Lines. Region: returns the resolution result based on end users' geographical locations. For details, see Configuring Region Lines.	Default
   TTL (s)	Cache duration of the record set on a local DNS server, in seconds. The value ranges from 1 to 2147483647, and the default value is 300. If your service address changes frequently, set TTL to a smaller value. Learn more about TTL.	300
   Value	IPv6 addresses mapped to the domain name. You can enter up to 50 different IP addresses, each on a separate line.	ff03:0db8:85a3:0:0:8a2e:0370:7334
   Weight	(Optional) Weight for the record set. The value ranges from 0 to 1000, and the default value is 1. This parameter is only configurable for public zone record sets. If a resolution line in a zone contains multiple record sets of the same type, you can set different weights to each record set. For details, see Configuring Weighted Routing.	1
   Tag	(Optional) Identifier of the record set. Each tag contains a key and a value. You can add up to 20 tags to a record set. For details about tag key and value requirements, see Table 2. NOTE: If your organization has configured tag policies for the DNS service, you need to add tags to your record sets based on the tag policies. If you add a tag that does not comply with the tag policies, record sets may fail to be created. Contact the administrator to learn more about tag policies.	example_key1 example_value1
   Description	(Optional) Supplementary information about the record set. The description can contain no more than 255 characters.	-

   Table 2 Tag key and value requirements

   Parameter	Requirements	Example Value
   Key	Cannot be left blank. Must be unique for each resource. Can contain no more than 36 characters. Cannot start or end with a space nor contain special characters =*<>\,|/	example_key1
   Value	Cannot be left blank. Can contain no more than 43 characters. Cannot start or end with a space nor contain special characters =*<>\,|/	example_value1

7. Click OK.
8. Switch back to the Record Sets tab.

   The added record set is in the Normal state.
