Know exactly what IPs you have assigned

Before you start to change your environment it would be best to know exactly what IPs you have assigned. Fortunately AWS created a tool just for that job

View Public IP insights - In order to make it easier for you to monitor, analyze, and audit your use of public IPv4 addresses use Amazon VPC IP Address Manager available no charge.

• Note: your Cost and Usage Report (CUR) now includes comprehensive usage data related to both in-use and idle public IPv4 addresses. You should know that as of June 1, 2024 the CUR will be deprecated and replaced by Data exports which is accessible now.
