What is an Elastic IP?
An Elastic IP is a static public IPv4 address provided by AWS.
Benefits:
  • Persistent public IP address
  • Remains the same after instance reboot
  • Useful for production servers and DNS mappings
  • Can be reassigned to another instance if needed
Unlike normal public IPs, Elastic IPs do not change when an instance stops and starts.
