Elastic IP (EIP)
A static public IPv4 address you reserve in AWS and attach to an instance or network interface so its internet-facing IP doesn't change.
"I need a stable public IP for my server so DNS, firewalls, and clients always reach the same address."
An Elastic IP is an AWS-managed public IPv4 address you allocate to your account and can attach/detach to EC2 instances or ENIs, preserving a consistent public endpoint even if the underlying instance is replaced.
