IP addresses can be categorized as private and public addresses. Private IP addresses cannot be reached via the Internet, whereas public IP addresses can. For instance, most home networks have a router. This router will have a public IP address that is accessible through the Internet. Devices that are behind the router such as your laptop, gaming consoles and smartphones have private IP addresses that are unique and registered on the home network.
An Elastic IP address is a public IPv4 address, which is reachable from the Internet. If your instance does not have a public IPv4 address, you can associate an Elastic IP address with your instance to enable communication with the Internet; for example, to connect to your instance from your local computer.
