CreateNatIp - NAT Gateway - Alibaba Cloud Documentation Center

Creates a NAT IP address for a Virtual Private Cloud (VPC) NAT gateway.

Operation description

CreateNatIp is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call the ListNatIps operation to query the status of the task.

If a NAT IP address is in the Creating state, the NAT IP address is being created. In this case, you can only query the NAT IP address and cannot perform other operations.
If a NAT IP address is in the Available state, the NAT IP address is created.

You cannot repeatedly call the CreateNatIp operation to create a NAT IP address within a specific period of time.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

Request parameters

Parameter	Type	Required	Description	Example
RegionId	string	Yes	The region ID of the NAT gateway to which the NAT IP address that you want to create belongs. You can call the DescribeRegions operation to query the most recent list of regions.	eu-central-1
NatGatewayId	string	Yes	The ID of the Virtual Private Cloud (VPC) NAT gateway for which you want to create the NAT IP address.	ngw-gw8v16wgvtq26vh59****
NatIpName	string	Yes	The name of the NAT IP address. The name must be 2 to 128 characters in length, and can contain letters, digits, periods (.), underscores (_), and hyphens (-). It must start with a letter. The name must start with a letter and cannot start with `http://` or `https://`.	newnatip
NatIpDescription	string	Yes	The description of the NAT IP address. The description must be 2 to 256 characters in length and start with a letter. The description cannot start with `http://` or `https://`.	test
DryRun	boolean	No	Specifies whether to perform only 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.	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 token, but you must make sure that the token 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 request ID as the client token. The request ID may be different for each request.	5A2CFF0E-5718-45B5-9D4D-70B3FF3898
NatIpCidr	string	Yes	The CIDR block to which the NAT IP address belongs.	192.168.0.0/24
NatIp	string	No	The NAT IP address that you want to create. If you do not specify an IP address, the system randomly allocates an IP address from the specified CIDR block.	192.168.0.34
