Is there any way to turn inelastic IP into elastic IP on aws?

I did some research and I don’t think it’s possible, but I thought that I would ask here just to make sure.

My predecessor decided to use the public and private IP address of one of our database servers in an extremely large number of places, now that we are going to resize this database server by going through and changing all these IP addresses, a lot of time and the ability to skip one pretty high.

I am wondering if it is even possible to take the current IP address on the server (which is not flexible), and some can turn it into a flexible IP. To clarify, I do not want to add a new elastic IP address to the server, but rather use the IP address that is currently assigned to it and make it elastic. If this is not what I can do with the SDK / Console, is that what Amazon can do behind the scenes if we get support?

Thanks!

No, It is Immpossible.

Elastic IP addresses are a separate pool of public IP addresses. There is no public means of translating a public (or private) IP address into Elastic IP.

Amazon's standard support is unlikely to make such a switch for you. Although technically an Amazon network engineer may possibly make such a switch, it is very unlikely that support can do this.

Until you complete the instance, its static IP address must remain assigned to it for Amazon documentation ( https://aws.amazon.com/articles/1346 ).

now that we will resize this database server

You can resize the instance and save its static IP address without terminating it (and thus without losing the static IP address). The moment you terminate this instance, you lose the static IP address, so you resize it without terminating it.

Amazon can manually create a reverse DNS entry for the mail server and, as you know, implement the features that users request, so I think it might be worth it. I would try.
