Record Set Tags

Scenarios

A tag is the identifier of a record set. Adding tags to record sets helps you identify and manage your record sets. You can add tags when adding a record set or add tags to an existing record set. Up to 20 tags can be added to a record set.

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.

A tag consists of a key and value pair. Table 1 lists the tag key and value requirements.

**Table 1** Tag key and value requirements

Value	Can be left blank. Can contain a maximum of 255 characters. Can contain letters, digits, spaces, and the following special characters: _.:/=+-@	example_value1
