Request parameters


The ID of the IP address pool.


The name of the IP address pool.

This parameter is optional. The name must be 1 to 128 characters in length, and can contain digits, periods (.), underscores (_), and hyphens (-). The name must start with a letter but cannot start with http:// or https://.


The description of the IP address pool.

This parameter is optional. If you enter a description, the description must be 2 to 256 characters in length, and cannot start with http:// or https://.


The client token that is used to ensure the idempotence of the request.

You can use the client to generate the token, but you must make sure that the token is unique among different requests. The token can contain only ASCII characters.

Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

Specifies whether to perform a dry run, without performing the actual request. Valid values:

  • true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, 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): performs a dry run and performs the actual request. If the request passes the dry run, a 2xx HTTP status code is returned and the operation is performed.

The region ID of the IP address pool that you want to modify.
