# CreateIpv6Block

## 1. 接口描述

本接口(CreateIpv6Block)用于创建一个或多个IPv6 Cidr Block。

#### 准备工作

* 查询库存：调用[`DescribeAvailableIpv6Resources`](/api-reference/cn/compute/bmc/cidr-block/describeavailableipv6resources.md)查看指定地区的资源供给情况。

{% hint style="info" %}
**注意事项**

* 每个Ipv6 Cidr Block包含500个可用的IP。
* 本接口为异步接口，当创建Cidr Block请求下发成功后会返回一个`ID`列表，此时创建Cidr Block操作并未立即完成。在此期间Cidr Block的状态将会处于`CREATING`，Cidr Block创建结果可以通过调用`DescribeCidrBlocks` 接口查询，如果Cidr Block状态由`CREATING`(创建中)变为`AVAILABLE`，则代表Cidr Block创建成功，`CREATE_FAILED`代表Cidr Block创建失败。创建过程中不可对Cidr Block进行任何操作。
  {% endhint %}
