Changing the Subnet of an ENI

Last updated: 2020-09-28 11:18:46


  • You can only change the subnet of a primary ENI.
  • You must unbind all secondary IPs before you change the subnet of an ENI.
  • You can only change the subnet of an ENI to another subnet within the same availability zone.
  • Changing the subnet will automatically restart the associated instance and cause business interruption for about 30 seconds, so proceed with caution.
  1. Log in to the VPC Console.
  2. Choose IP and ENI -> ENI in the left sidebar to go to the ENI list page.
  3. Locate the ENI you want to change the subnet, and click its ID/Name to enter the details page.
  4. In the Basic Information tab, click Change Subnet next to Subnet.
  5. Select the subnet you want to use and specify a new primary IP in the pop-up window.
  6. Click OK.
