# VPC子网接口与OpenStack Neutron子网接口的区别是什么？
#### 两者区别
子网接口分为[VPC子网](https://support.huaweicloud.com/api-vpc/vpc_subnet01_0000.html)接口、[子网](https://support.huaweicloud.com/api-vpc/vpc_subnet02_0000.html)接口两种。两者均可以正常创建、查询、更新、删除子网。
两者的区别及容易混淆的地方在于网络ID、子网ID两个参数的含义。
登录管理控制台，查看子网的基本信息，可以看到网络ID、子网ID两个字段。

- 调用VPC子网接口时，使用的子网ID为[图1]所示的网络ID，例如：a22724a0-b77b-44b4-b731-afd3a4839863。
- 调用OpenStack neutron子网接口时，使用的子网ID为[图1]所示的子网ID，例如：f32a3acf-2312-41d0-947c-13d377a35059。
