How can I delete or cancel public IPv4 addresses under VPC?

0

So about 2 months ago, I tried spinning up a PostgresSql instance for one of my projects using Aurora and RDS, which went well, but I ended up getting billed (which I didn't expect) so I decided to shutdown the whole thing. It turns out since then, I've been receiving this recurrent bill on the usage of Public IPv4 addresses, but I can't seem to figure out where it is coming from. It says it is under VPC, but when I got to the VPC section, I don't see anything up and running. Please help! Billing Screenshot

  • Guys, I think I found the problem. The bills stem from EU (Frankfurt) but my region was set to us-east-1 the whole time, hiding the EC2 database instance I had running.

Hey Charles,

It sounds like there might be an Elastic IP still hanging around. AWS charges for those if they’re not in use, even if everything else is shut down.

Try checking the Elastic IPs section under VPC - look at the Allocation ID and see if it’s attached to anything. If it’s not, you can just release it to stop the billing.

  • Hello, Pavan. I've checked and it says "No Elastic IP addresses found in this Region"

Hello.

Please try to find the public IPv4 in your AWS account using the method described in the following blog.
You can use Public IP Insights to find out which AWS resources are using public IPv4.
