Explanation:
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/resources.html
As per the document defined, new IPs should be reserved not the same ones.

Elastic IP Addresses are static IP addresses designed for dynamic cloud computing. Unlike
traditional static IP addresses, however, Elastic IP addresses enable you to mask instance or
Availability Zone failures by programmatically remapping your public IP addresses to instances in
your account in a particular region. For DR, you can also pre-allocate some IP addresses for the
most critical systems so that their IP addresses are already known before disaster strikes. This
can simplify the execution of the DR plan.
