Anycast Elastic IP Address:API overview

Last Updated:Jul 03, 2026

API standards and multilingual preset SDKs

The OpenAPI of this product (Eipanycast/2020-03-09) uses the RPC signature style. We have encapsulated SDKs for common programming languages for developers. Developers can download the SDK to directly call this product's OpenAPI without worrying about technical details. If the existing SDK does not meet your needs, you can use the signature mechanism for self-signing integration. Since the details of self-signing are very complex, it may take around 5 business days. Therefore, we recommend joining our DingTalk service group (147535001692) and conducting signature integration under expert guidance.

Before using the API, you need to prepare your identity account and access key (AccessKey) to effectively access the API through client tools (such as SDK and CLI). For details, see Obtain an AccessKey.

Custom signature scenarios

If your business scenario has special requirements and you need to integrate the API through self-signing, we recommend consulting our technical support team first (DingTalk service group: 147535001692) to obtain professional guidance and ensure efficient integration.

Account and security preparation

Alibaba Cloud accounts have full administrative permissions over all resources. Once an AccessKey is compromised, all associated resources will be at risk of unauthorized access. To ensure security, it is recommended to create a RAM user with only API access permissions and configure its AccessKey, while configuring RAM policies based on the principle of least privilege (PoLP). Use the Alibaba Cloud account only in specific scenarios where Alibaba Cloud account permissions are explicitly required.

Description

AllocateAnycastEipAddress AllocateAnycastEipAddress The AllocateAnycastEipAddress operation creates an Anycast EIP instance.
AssociateAnycastEipAddress AssociateAnycastEipAddress Associates an Anycast EIP with a specified backend cloud resource.
UnassociateAnycastEipAddress UnassociateAnycastEipAddress Disassociates an Anycast EIP from an endpoint.
ReleaseAnycastEipAddress ReleaseAnycastEipAddress Releases an Anycast EIP instance.
ModifyAnycastEipAddressSpec ModifyAnycastEipAddressSpec Modifies the bandwidth of an Anycast EIP instance.
ModifyAnycastEipAddressAttribute ModifyAnycastEipAddressAttribute Changes the name and description of an Anycast EIP instance.
UpdateAnycastEipAddressAssociations UpdateAnycastEipAddressAssociations If an Anycast EIP instance is associated with backend resources in multiple regions, you can modify the mappings between access points and origin servers. You can call the UpdateAnycastEipAddressAssociations operation to add or remove access points for a specified origin server, which is an associated cloud resource instance.
DescribeAnycastEipAddress DescribeAnycastEipAddress Queries the details of a specified Anycast EIP instance, including its status, peak bandwidth, and associated cloud resources.
DescribeAnycastPopLocations DescribeAnycastPopLocations Queries the access points in a specified access area.
ListAnycastEipAddresses ListAnycastEipAddresses Queries the details of Anycast EIPs in a specified access area, including their status, peak bandwidth, and information about bound cloud resources.
DescribeAnycastServerRegions DescribeAnycastServerRegions Queries the regions where backend services can be attached to an Anycast EIP.
