AWS started charging – from February 2024 – for any public IP that is being used (previously only IPs that were not used were charged). The current value of monthly usage (730h average) per IP, in any region, is US$3.65 . Check the official details (“Public IPv4 Address” item).
In response to requests, we created a new rule within Best Practices that estimates the potential amount to be paid.
Instances with billed public IP addresses
The official value is found in the “ VPC ” product. We will soon add the detailed cost of EC2 instance IPs by ID and you will be able to check the values in other FINOPS tools (inventory, components, analytics, etc.).
Remember that ASGs, Kubernetes, SPOT systems that create instances with public IPs will also be charged for the time they are active.
