Explanation: The EC2 instances are registered with the load balancer using the IP addresses associated with the instances. When an instance is stopped and then started, the IP address associated with the instance changes. This prevents the load balancer from routing traffic to the restarted instance.

Failure to do so may prevent the load balancer from performing health checks and routing the traffic to the restarted instance.
