<li>Stopped -- EC2 is not active and is equivalent to shutdown. Note one can start and stop an instance if it has Amazon EBS volume in its root device. IPv4 &amp; IPv6 address is retained in this state and is reused when the EC2 instance is restarted. AWS does not charge usage or data transfer fees for stopped instances.

<h3 id="heading-difference-between-stop-amp-stop-hibernate">Difference between stop &amp; stop-hibernate</h3>
In the stop state, one can change attributes of EC2 instances like instance type. However, any data from the instance memory (RAM) is lost.
When you stop-hibernate an instance, any contents from the instance memory (RAM) are stored in the EBS root volume. Instances can be hibernated if instance meet the hibernation prerequisites

### Difference between stop & stop-hibernate

In the stop state, one can change attributes of EC2 instances like instance type. However, any data from the instance memory (RAM) is lost.

When you stop-hibernate an instance, any contents from the instance memory (RAM) are stored in the EBS root volume. Instances can be hibernated if instance meet the hibernation prerequisites
