Can I remove the public IP on my instance without terminating it?

Question

I have several instances on a vpc that communicate with each other through their private IPs. Each instance was launched some time ago and assigned a random public IP which is not used for anything. Since anything that is public presents a vulnerability and they are not used at all, I would like to remove them.

Is it possible to Remove public Ip Addresses without terminating the instance?

Answer 1

If you are using an Elastic IP then it would be possible. Because when you remove it, then the normal public IP address will be given. Or you can create an image of the instance, and create another EC2 instance using it which will surely have a different IP.
