# DeleteSubnets

## 1. API Description

This API (DeleteSubnets) is used to deletes one or more subnets.

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

* Before deleting a subnet, clean up all resources under it, including network interfaces, instances, NAT gateways, HA VIPs, etc.
* The default subnet cannot be deleted.
* Batch deletion is supported. A failure to delete one subnet does not affect the others; failure details (subnet ID, error code, error message) are returned in the `failedSubnets` field of the response.
