EC2 Instances will not keep elastic IP

Question

So, I don\'t understand what is going on here... I have (3) Micro EC2 Instances which are launched (without elastic ip)

I then go to Network Security->Elast

Answer 1

If you create a VPC and then re-provision the 3 micro instances under the VPC, EIPs you associate will remain associated during stop/start cycles. You won't be able to reuse your existing EC2 instances or EIPs; you'll have to recreate them under the new VPC.
