Is ping supposed to test if an IP address has been assigned to a network interface and if the network interface is reacheable?
Stephen replies at Why is some virtual network interface assigned private IP address, while some is assigned loopback IP address?
ping tests whether packets can be sent to and received back from a given IP address, no more, no less; it doesn’t concern itself with network interfaces.
Can you characterize the cases when ping can receive response from an IP address which is not assigned to a network interface?
Are loopback addresses the only cases?
I asked these, because I originally thought an IP address needs to be bound to an network interface in order to communicate with other IP address
Thanks.

What I don’t understand is why you start with a question (“Is ping supposed to test if an IP address has been assigned to a network interface and if the network interface is reacheable?”) which is answered by the quote. Are you looking for corroboration of what I wrote? Or are you only interested in your second (and titular) and third questions?

Also, are you considering only local interfaces, or do you want to know about all possible interfaces anywhere in the world? I.e., do you want an answer which covers what happens when you runping 8.8.8.8?
