1. API Description

Domain name for API request:

This API (AllocateAddresses) is used to apply for one or more Elastic IPs(EIP).

  • EIP is a static IP designed for dynamic cloud computing. With EIP, you can quickly remap the EIP to another instance, shielding off the instance failures.
  • Your EIP is associated with a Tencent Cloud account, instead of an instance, until you choose to explicitly release it or your payment is more than seven days overdue.
  • The platform imposes quotas on number of EIPs that a user can request for each region.

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

Note: This API supports Finance regions. Since Finance regions and non-Finance regions are isolated and not interconnected. If the common parameter Region is a Finance region (such as ap-shanghai-fsi), you need to specify a domain name containing the Finance region that should be identical to the value of Region field, for example:
