IPs

You must have noticed the presence of an internal and an external IP associated with our VMs. Each GCP project comes with a Virtual Private Cloud (VPC) network, which is automatically created with the project. A VPC is basically a private and isolated virtual network partition that enables your resources to talk to each other within a given project, while allowing control of external access to the VPC. Upon creation, each instance gets an internal IP address assigned to allow other resources within the project's VPC to communicate with the instance. To communicate with entities outside the VPC, including connections with the internet, the instance requires an external IP address.

IP addresses, both internal and external, can be ephemeral ...
