This topic describes how to delete an IPv6 address when your Elastic Compute Service (ECS) instance no longer requires the IPv6 address. After you delete the IPv6 address of an instance, the instance can still use its IPv4 address.


The instance is in the Running or Stopped state.


  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Instances.
  3. In the top navigation bar, select a region.
  4. Select the ECS instance to which you want to assign an IPv6 address and click More in the Actions column.
  5. Choose Network and Security Group > Manage Secondary Private IP Address.
  6. Click Unassign next to IPv6 Address.
  7. Click OK.
