Assigning a floating IP to an instance
Your freshly made machine lives on your own private network, created by you, and is thus currently unreachable from the rest of the world. To enable outside access to the machine you would need to assign a floating IP address to it.
If this is the first time you use a floating IP, there are probably no IP allocated to your project. To allocate an IP to your project you could use the following command:
