Amazon EC2 Elastic Load Balancer: Does its IP ever Change?

Question

Does the ELB\'s IP Ever Change once setup, or will it always access instances from the same location during its lifetime no matter what might be going on with it be

Answer 1

The short answer: Yes, ELB's IP addresses (both the ones that are publicly distributed to clients of your service, and the internal IPs from which ELB sends traffic to your instances) dynamically change.
