Alibaba Cloud DNS PrivateZone (PrivateZone) is an Alibaba Cloud private domain name resolution and management service based on Virtual Private Cloud (VPC). After you connect a virtual border router (VBR) or a Cloud Connect Network (CCN) instance to a transit router, the on-premises network associated with the VBR or CCN instance can access PrivateZone by using the transit router.
Limits
The on-premises networks connected to VBRs or CCN instances must be deployed in the same region as the PrivateZone service.
For example, if the PrivateZone service is deployed in the China (Beijing) region, only on-premises networks connected to VBRs or CCN instances in the China (Beijing) region can access the PrivateZone service.

Prerequisites
- PrivateZone is deployed. For more information, see Subscribe Service.
- The VPC associated with PrivateZone and the VBR or CCN instance associated with the on-premises network are connected to the same transit router. For more information, see Create a VPC connection, Create a VBR connection, and Associate a CCN instance with a transit router.
- If your on-premises network uses a CCN instance to connect to Alibaba Cloud, and the CCN instance and the VPC or transit router belong to different accounts, you must grant the required permissions to the CCN instance. For more information, see Authorize CCN instances to use the PrivateZone service.
