# UnassociateEipAddress

## 1. API Description

This API (UnassociateEipAddress) is used to disassociate elastic IPs from resources in the same region.

{% hint style="info" %}
**Notes**

* The interface returns the set of EIP IDs that failed to be unbound. An empty set indicates that all of them were unbound successfully.
* If an elastic IP has already been unbound, performing the operation again does not report an error.
* The default elastic IP cannot be unbound.
  {% endhint %}
