When you need to point the domain name to ALB with A, you find that ALB does not have a fixed IP.
Therefore, you can rely
on the following two methods to allow ALB to obtain a fixed IP. Here comes some example:
1. NLB+ALB
If your Application Load Balancer requires a static IP address, it can be registered behind a Network Load Balancer.
The Network Load Balancer will assign a static IP address and serve as a fixed entry point to your Application Load Balancer.
2. AGA+ALB
Use AWS Global Accelerator to obtain static IP addresses and associate them with ALB
