Last night I left my computer running Norton360, full system scan. This morning Security History shows multiple (& continuing) Info messages: "IP address has disappeared from adapter Teredo Tunneling Pseudo-Interface (IP address: .......". Each is followed immediately (often same hh:mm:ss) with "Protecting your connection to a newly detected network on adapter "Teredo Tunneling Pseudo-Interface" (IP address: .......".
What does this mean? Internet search produced discussions of IPV4, IPV6, etc . . . none of which I understand, AT ALL. Can this be explained in "simple" terms that even I can understand? Yes, it says "No Action Required", but that's not really very comforting when I see so many such entries.
