When you create an instance, it receives a private IP address. Your instance is accessible for other instances with this private IP address . If you want to access your instance(s) over the internet, you'll need to assign a (floating) IP to these instances. A floating IP is an IP address on a external network. A floating IP address gives access to an instance to a private network from an external network.
