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 behind the scenes at Amazon?

Note: originally ELB (Elastic Load Balancer) referred to an L7 balancer what is now called ALB (Application Load Balancer), which indeed has changing IPs.
But there's an other kind of ELB, the L4 NLB (Network Load Balancer), which by default uses static IP addresses (and you can stick Elastic IP as well, if you want flexibility of moving the ElasticIP around).
So it is important to distinguish which ELB we are talking about - ALB or NLB.
