Ok. Let's get back to some basics to be sure we are talking about the =
same things.=20
First, do you believe that a residential customer of an ISP will get an =
IPv6 /56 assigned for use in their home? Do you believe that residential =
customer will often choose to multihome using that prefix? Do you =
believe that on an Internet that has its primary layer 3 protocol is =
IPv6 that a residential customer will still desire to do NAT for =
reaching IPv6 destinations?=20
I am looking forward to your response.
