Every network interface that you have on your system that has IPv6 enabled should have at least one address on it that's inside fe80::/10. This leads to the issue that addresses in the fe80::/10 space are not unique since most hosts have at least one network interface and a loopback interface, each of which could have the exact same fe80::/10 address configured on it or reachable through it. The %foo syntax is how one specifies which interface to use. In the olden days one HAD TO specify the interface with %foo; the command would fail if you didn't. These days Linux lets you omit the %foo part. I think it might just try your first non-loopback network interface if you don't specify it. The response in the ping output does let you know which interface the response came from. I am not sure of the exact answer for this since I don't think we have the address fe80:: configured anywhere. You are getting a response from fe80::fcff:ffff:feff:ffff which is the automatic link-local address on BitFolk's side of your virtual Ethernet. I don't know why it responds to you asking fro fe80::. It does that for me too on newer versions of Debian in a VM but not on older versions. All I know is that fe80:: is some sort of multicast address. But the answer will be basically the same with some other minor wrinkle as to why that is happening. Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting "It is I, Simon Quinlank.
