(including "gone" from > home and enterprise networks) I think it will be used for email and the web for at least ten years. I think there will be a need to talk to legacy IPv4-only devices for about that long, perhaps a bit longer. But IPv4 is already difficult to use for a great many applications, and it will only get worse with the imposition of LSN. A home network that only supports IPv4, or which makes IPv6 as crippled as IPv4, is not a desirable goal.
