Disassociating an EIP from an Instance or a Network Interface

You can disassociate an External address IP (EIP) from an instance or a network interface it is associated with.

To disassociate an EIP from a NAT gateway, you need to delete the NAT gateway. For more information, see Deleting a NAT Gateway.

After you disassociate it, the EIP is still allocated to your account and can be associated again. If you do not need the EIP anymore, you can release it from your account. For more information, see Releasing an EIP from Your Account.

  2. Check the box of the VM whose public IP you want to unlink.
    The VM is selected and an action menu appears.

    The public IP is unlinked from the VM.

Disassociating an EIP from an Instance or a Network Interface Using AWS CLI

To disassociate an EIP from an instance, use the disassociate-address command following this syntax:

Request sample
$ aws ec2 disassociate-address \
    --profile YOUR_PROFILE \
    --public-ip 111.1.1.1 \
    [--association-id NOT_SPECIFIED] \
    --endpoint https://fcu.eu-west-2.outscale.com

This command contains the following attributes that you need to specify:

  • (optional) profile: The named profile you want to use, created when configuring AWS CLI. For more information, see Installing and Configuring AWS CLI.

  • (optional) public-ip: The EIP.

  • (optional) association-id: The ID of the association.

    • In the public Cloud, you need to specify the public-ip attribute.

    • In a VPC, you need to specify the association-id attribute.

  • endpoint: The endpoint corresponding to the Region you want to send the request to.

The EIP is disassociated and is available again in your account.
