1. API Description

Domain name for API request: vpc.intl.tencentcloudapi.com.

This API is used to bind an Elastic IP (EIP for short) to the specified private IP of an instance or ENI.

• Binding an EIP to a CVM instance is actually binding the EIP to the primary private IP of the primary ENI on the CVM instance.
• When an EIP is bound, the public IP previously bound to the CVM instance will be unbound and released automatically.
• To bind another EIP to the private IP of the specified ENI, you must first unbind the EIP.
• To bind an EIP to a NAT Gateway, use the API AssociateNatGatewayAddress.
• An EIP cannot be bound if it’s overdue or blocked
• Only EIP in the UNBIND status can be bound.

A maximum of 10 requests can be initiated per second for this API.
