AddIpamPoolCidr-Virtual Private Cloud(VPC)-阿里云帮助中心

Provisions a CIDR block for an IPAM pool.

Operation description

Before provisioning a CIDR block, ensure that you have created an IPAM pool. You can call CreateIpamPool to create a pool.
If the parent pool does not have a provisioned CIDR block, you cannot provision a CIDR block for the child pool.
If the parent pool has a provisioned CIDR block, you can provision a CIDR block for the child pool. The provisioned CIDR block must be a subset of the CIDR block provisioned for the parent pool.
If the parent pool has a provisioned CIDR block and a CIDR allocation, the CIDR block provisioned for the child pool cannot conflict with the existing CIDR allocation.
Requests to provision a CIDR block for a pool must be initiated from the IPAM hosted region.
The CIDR block provisioned for an IPAM pool cannot conflict with the CIDR blocks provisioned for other pools within the same scope.
The number of CIDR blocks that can be provisioned for a pool is limited. By default, a public IPv6 top-level pool supports up to 1 CIDR block, and other types of pools support up to 50 CIDR blocks.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The ID of the IPAM hosted region. You can call the DescribeRegions operation to query region IDs.	cn-hangzhou
IpamPoolId	string	Yes	The instance ID of the IPAM pool.	ipam-pool-6rcq3tobayc20t****
Cidr	string	No	The CIDR block to provision. Note Private top-level pools support provisioning only by specifying a CIDR block.	192.168.1.0/24
NetmaskLength	integer	No	The netmask length used to provision a CIDR block. Note Public IPv6 top-level pools support provisioning only by specifying a netmask length.	24
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: Performs a dry run. The system checks the required parameters, request format, and service limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned. false (default): Sends a normal request. If the request passes the dry run, an HTTP 2xx status code is returned and the operation is performed.	false
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the value, but you must ensure that it is unique among different requests. The client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the client token. The RequestId of each API request is different.	123e4567-e89b-12d3-a456-426655440000

Response elements
