Elastic IP addresses (EIPs) in Amazon Web Services (AWS) are a useful resource for static public IP addresses that you can allocate to your AWS resources, such as EC2 instances, NAT Gateways, and Elastic Load Balancers. However, over time, unused EIPs can accumulate and add unnecessary costs to your AWS bill.

How to delete all unused Elastic IP addresses across all AWS Regions

# https://github.com/dannysteenman/aws-toolbox # # License: MIT # # This script finds and deletes all unused Elastic IPs in all AWS Regions import boto3 ec2 = boto3.resource("ec2") unused_ips = {} for region in ec2.meta.client.describe_regions()["Regions"]: region_name = region["RegionName"] try: ec2conn = boto3.client("ec2", region_name=region_name) addresses = ec2conn.describe_addresses( Filters=[{"Name": "domain", "Values": ["vpc"]}])["Addresses"] for address in addresses: if ("AssociationId" not in address and address["AllocationId"] not in unused_ips ): unused_ips[address["AllocationId"]] = region_name ec2conn.release_address(AllocationId=address["AllocationId"]) print( f"Deleted unused Elastic IP {address['PublicIp']} in region {region_name}") except Exception as e: print(f"No access to region {region_name}: {e}") print(f"Found and deleted {len(unused_ips)} unused Elastic IPs across all regions:") print(unused_ips)

In this blog post, we have shown you how to create a Python script using the AWS Boto3 library to delete all unused Elastic IP addresses across all AWS regions.
