Enabling IPv6 Public Network
Log in to the VPC Console.
In the left directory, choose IP and Network Interface > Elastic IPv6.
Select the region where you want to enable IPv6 public network, and click Apply to enter the Apply for Elastic IPv6 page.
Check the CVM IPv6 address, set the upper limit of the target bandwidth, and then click Submit.
Note:
- After the CVM applies for an IPv6 address, public network access capability is disabled by default. You can manage the IPv6 public network capability through Elastic IPv6.
When the ISP type is BGP, the Elastic IPv6 address is the IPv6 address obtained by the CVM. Therefore, please ensure that the CVM has obtained an IPv6 address.
A single operation can support enabling public network access for up to 100 IPv6 addresses simultaneously. If more than 100 IPv6 addresses need to enable public network access, please operate in multiple batches.

Disabling IPv6 public network
Log in to the VPC Console.
In the left directory, choose IP and Network Interface > Elastic IPv6.
On the Elastic IPv6 list page, check the IPv6 address for which you want to disable the public network, and click Release.
Verify the information in the pop-up window and click OK to release the Elastic Ipv6. After the Elastic IPv6 is released, the public network access is disabled for the corresponding IPv6 address.
Adjusting IPv6 Public Network Bandwidth
Log in to the VPC Console.
In the left directory, choose IP and Network Interface > Elastic IPv6.
In the operation column of a single elastic IPv6, click Adjust Bandwidth.
In the pop-up Adjust Bandwidth dialog box, modify the upper limit of the public network bandwidth of the Elastic IPv6 and click Adjust.
