AWS EC2 - how to reserve assigned IP address
My AWS EC2 instances has been assigned IP addresses. Since I want to change machine type because of underutilization, I have to stop them and lose my assigned addresses. Is there any way how to reserve IP addresses I am currently running these instances with? Thanks.
If you stop the instance its IP will change. If you want a static public IP you can assign an Elastic IP address to your instance, if you want a static private IP you can launch your instance inside a VPC. So, if you haven't already applied one of these solutions, there's no way to preserve its current IP.
