AWS Config Rule: Elastic IP Attached


Fernando Honig

Last Update vor 8 Monaten

Description: Checks if all Elastic IP addresses that are allocated to an AWS account are attached to EC2 instances or in-use elastic network interfaces (ENIs).

Note: Results might take up to 6 hours to become available after an evaluation occurs.

Trigger type: Configuration changes

AWS Region: All supported AWS regions

How to Resolve Manually

This may come as a surprise, but you are charged over time for EIPs that you own, but do not have attached to an Instance or ENI. It is imperative that you keep on top of unused Elastic IP addresses, and this config rule will highlight any time you have an EIP which is not in use.

To resolve this manually, simply do one of the two following actions for each EIP not in use:

1. Assign the EIP to an Instance or elastic network interface (ENI)

2. Release the EIP back into Amazon's EIP pool.

Action 2 can be completed from the VPC Dashboard in AWS, after choosing Elastic IPs from the left menu. Select the EIP in question and from Actions, choose Disassociate Elastic IP address.
