Release unused/unattached AWS Elastic IP addresses
There was a problem that the LLM was not able to address. Please rephrase your prompt and try again.
Once the unattached Elastic IPs are identified, this task releases them from the AWS environment. By using the collected allocation IDs and regions, the script communicates with the EC2 service to release each unattached Elastic IP. This process ensures that these IPs are no longer reserved, contributing to cost savings and resource optimization.
