Alibaba Cloud DNS provides an automated removal mechanism to ensure the accuracy of DNS records.
Revocation mechanism
Detection mechanism: The system performs daily checks to verify that an Alibaba Cloud account still owns the public IP address resources for its PTR records in a specific region.
Automatic deletion: If a public IP address resource is released or no longer belongs to the Alibaba Cloud account, the system automatically deletes the corresponding PTR records.
Alert notifications: When a record is deleted, the system sends an alert notification by email and text message.
NoteEnsure that Alibaba Cloud DNS High Risk Notification is selected in Basic Recipient Management and that Receiving Channel is set correctly.
