Support for IPv6 Addressing
The following are observations regarding IPv6 addressing on the Alibaba Cloud:
- The IPv6 address range should be enabled on the VSwitch.
- By default, when creating an Elastic Compute Service (ECS) instance, an IPv4 address instead of an IPv6 address is assigned to the instance. To have the instance communicate over IPv6, configure an IPv6 address for the instance.
- IPv6 addressing is not supported on every ECS instance types. It depends on system resources selected during deployment. Refer to ECS instance type family.
- See Configure IPv6 addresses for information on how to configure an IPv6 address for the instance.
