Effective February 1, 2024 there will be a charge of $0.005 per IP per hour for all public IPv4 addresses, whether attached to a service or not (there is already a charge for public IPv4 addresses you allocate in your account but don’t attach to an EC2 instance). Public IPv4 Charge As you may know, IPv4 addresses are an increasingly scarce resource and the cost to acquire a single public IPv4 address has risen more than 300% over the past 5 years.
This change applies to all AWS services including https://aws.amazon.com/ec2/, https://aws.amazon.com/rds/ database instances, https://aws.amazon.com/eks/ nodes, and other AWS services that can have a public IPv4 address allocated and attached, in all AWS regions (commercial, https://www.amazonaws.cn/en/about-aws/china/, and https://aws.amazon.com/govcloud-us/).
In addition to helping you to make efficient use of public IPv4 addresses, Public IP Insights will give you a better understanding of your security profile. You can see the breakdown of public IP types and EIP usage, with multiple filtering options: You can also see, sort, filter, and learn more about each of the public IPv4 addresses that you are using: Using IPv4 Addresses Efficiently By using the new IP Insights tool and following the guidance that I shared above, you should be ready to update your application to minimize the effect of the new charge.
