Server Load Balancer:UpdateLoadBalancerAddressTypeConfig

Last Updated:Jul 22, 2025

Changes the network type of the IPv4 address for a Network Load Balancer (NLB) instance.

Operation description

  • Make sure that an NLB instance is created. For more information, see CreateLoadBalancer .

  • You can call the GetLoadBalancerAttribute operation to query the AddressType value of an NLB instance after you change the network type.

  • UpdateLoadBalancerAddressTypeConfig 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 GetJobStatus operation to query the task status:

    • If the task is in the Succeeded state, the network type of the IPv4 address of the NLB instance is changed.
    • If the task is in the Processing state, the network type of the IPv4 address of the NLB instance is being changed. In this case, you can perform only query operations.

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.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

  • Operation: the value that you can use in the Action element to specify the operation on a resource.
  • Access level: the access level of each operation. The levels are read, write, and list.
  • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
    • For mandatory resource types, indicate with a prefix of * .
    • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
  • Condition Key: the condition key that is defined by the cloud service.
  • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

ParameterTypeRequiredDescriptionExample
LoadBalancerIdstringYes

The ID of the NLB instance.

nlb-83ckzc8d4xlp8o****
AddressTypestringYes

The new network type. Valid values:

  • Internet: The nodes of an Internet-facing NLB instance have public IP addresses. The DNS name of an Internet-facing NLB instance is publicly resolvable to the public IP addresses of the nodes. Therefore, Internet-facing NLB instances can route requests from clients over the Internet.
  • Intranet: The nodes of an internal-facing NLB instance have only private IP addresses. The DNS name of an internal-facing NLB instance is publicly resolvable to the private IP addresses of the nodes. Therefore, internal-facing NLB instances can route requests only from clients with access to the virtual private cloud (VPC) for the NLB instance.
Internet
ZoneMappingsarray<object>No

The mappings between zones and vSwitches. You can specify up to 10 zones.

ZoneMappingobjectNo

The mapping between the zone and a vSwitch in the zone.

VSwitchIdstringNo

The ID of the vSwitch in the zone. You can specify only one vSwitch (subnet) in each zone of an NLB instance.

vsw-bp10ttov87felojcn****
ZoneIdstringNo

The zone ID of the NLB instance.

You can call the DescribeZones operation to query the most recent zone list.

cn-hangzhou-a
AllocationIdstringNo

The ID of the elastic IP address (EIP).

eip-bp1aedxso6u80u0qf****
EipTypestringNo

The type of the EIP. Valid values:

  • Common: an EIP
  • Anycast: an Anycast EIP
Note This parameter is required only if AddressType is set to Internet.
Common
DryRunbooleanNo

Perform a dry run without actually making the request. Valid values are:

  • true: Perform 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 check, an error message specifying the issue is returned. If the request passes, the DryRunOperation error code is returned.
  • false (default): Check the request and perform the operation. If the request passes the check, a 2xx HTTP status code is returned, and the operation is performed.
false
ClientTokenstringNo

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

You can use the client to generate this value. Ensure that the value is unique among all requests. Only ASCII characters are allowed.

Note If you do not specify this parameter, the value of RequestId is used.**** RequestId of each request is different.
123e4567-e89b-12d3-a456-426655440000
RegionIdstringNo

The region ID of the NLB instance.

You can call the DescribeRegions operation to query the most recent region list.

cn-hangzhou
