After you create a VPC-type ECS instance, you can change the private IP address of the instance directly or by changing the VSwitch of the instance.


No secondary private IP addresses are configured for elastic network interfaces (ENIs) of the instance.


  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. Find the instance for which you want to modify the private IP address and choose More > Instance Status > Stop in the Actions column.
  5. After the instance is stopped, click the instance ID.
  6. In the Configuration Information section, choose More > Modify Private IP Address.
  7. In the Modify Private IP Address dialog box, modify the parameters and click Modify.
    • If you need to change the VSwitch, make sure that the selected VSwitch resides within the same zone as the instance.
    • If you do not need to change the VSwitch, modify the private IP address.

  8. Go back to the Instances page. Find the instance and choose More > Instance Status > Start in the Actions column.
    Note The new private IP address takes effect after the ECS instance is started.
