Overview

Private zones provide configurations for private domain names that are only applicable within VPCs, and they map private domain names to private IP addresses and resolve domain names within VPCs.

• You can create any domain names without registering them.

• One private zone can be associated with multiple VPCs, and domain names are valid only in VPCs.

To use private domain names, you must first create a private zone and associate VPCs with it.

This chapter describes how to create and manage private zones.

Table 1 Private zone operations

Operation	Description	Constraint
Creating a Private Zone	Create a zone for your domain name.	Private zones are project-level resources. When you create a private zone, select a region and project. Each account can create a maximum of 50 private zones. Private domain names must meet the following requirements: Domain name labels are separated by dot (.), and each label does not exceed 63 characters. A domain name label can contain letters, digits, and hyphens (-) and cannot start or end with a hyphen. The total length of a domain name cannot exceed 254 characters.
Managing Private Zones	Modify, delete, and query private zones.	The name of a private zone cannot be modified after the zone is created. After a private zone is deleted, all its record sets will also be deleted.
Associating a VPC with a Private Zone	Configure private domain names for VPCs.	You can only associate VPCs that you have created using your own account. Each VPC can be associated only with one private zone. However, a private zone can have more than one VPC associated with it.
Disassociating a VPC from a Private Zone	Disassociate a VPC from a private zone.	After the disassociation, private domain names will not take effect in the VPC. If a private zone is only associated with one VPC, you cannot disassociate it.
