An IP address used by a virtual machine to communicate over a physical network is called a what?

• A. Provider Address
• B. Public IP Address
• C. Private IP Address
• D. Loopback Address

Answer: (A)

The concept here is that the IP address a virtual machine uses to reach the outside physical network is the address provided by the network provider, or the administrator who manages the host’s network. This is called a provider address because it is assigned and managed by the provider for access to the physical network beyond the host. It’s different from a loopback address, which stays inside the same host and is used for testing or inter-process communication on the same machine. It’s also distinct from a private IP address, which is intended for use within a private, internal network and may not be routable on the broader physical network, and from a public IP address, which is globally routable on the internet. In VM setups, you typically need an address that the physical network can route to the VM, and that’s the provider-supplied address.
