1. API Description

Domain name for API request:

This API (TransformAddress) is used to convert an ordinary public IP into an Elastic IP (EIP).

  • The platform imposes a quota on the number of attempts to unbind an EIP and reallocate an ordinary public IP per day for each region (See Overview of EIP products). The above quota can be obtained through API DescribeAddressQuota.
