This topic describes how to enable an IPv6 CIDR block for a Virtual Private Cloud (VPC) network. After the IPv6 CIDR block is enabled, the system automatically creates an IPv6 gateway free of charge for the VPC network. You can use the IPv6 Gateway to manage the IPv6 Internet bandwidth and set egress-only rules.
- Log on to the VPC console.
- Select the region where your VPC network is deployed.
Note The following regions support IPv6 gateways: China (Beijing), China (Zhangjiakou), China (Hohhot), China (Hangzhou), China (Shanghai), China (Shenzhen), China (Chengdu), China (Hong Kong), Singapore (Singapore), and US (Virginia).
- On the VPCs page, find the target VPC network and click Enable IPv6 CIDR Block in the IPv6 CIDR Block column.
- In the Enable IPv6 CIDR Block dialog box, select Enable IPv6 CIDR Block of all VSwitches in VPC, and then click OK.
If you do not select Enable IPv6 CIDR Block of all VSwitches in VPC, you must enable IPv6 CIDR Block for each VSwitch. For more information, see Enable IPv6 for a VSwitch.
