This topic describes how to assign an IPv6 address to a Windows Elastic Compute Service (ECS) instance. You can assign an IPv6 address to a Windows instance when you create the instance. You can also assign an IPv6 address to an existing Windows instance.
Assign an IPv6 address when you create an ECS instance
Prerequisites: The virtual private cloud (VPC) and vSwitch of the instance are assigned IPv6 CIDR blocks. For more information, see Create an IPv6 VPC.
- In the Basic Configurations step, filter out IPv6-supported instance types, and then select an instance type.
- In the Networking step, select a VPC and a vSwitch for which IPv6 is enabled, and then select Assign IPv6 Address Free of Charge.
- In the Preview step, confirm that the IPv6 address is selected.
Assign an IPv6 address to an existing instance
- The instance supports IPv6. For more information about the instance types that support IPv6, see Instance families.
- The network type of the instance is VPC. The VPC and vSwitch of the instance are assigned IPv6 CIDR blocks. For more information, see Create an IPv6 VPC.
- The instance is in the Running or Stopped state.
To assign an IPv6 address to an existing instance, perform the following operations:
- Log on to the ECS console.
- In the left-side navigation pane, choose .
- In the top navigation bar, select a region.
