RE: I-D ACTION:draft-baker-v6ops-end2end-00.txt



Hello Fred,

I enjoyed reading this informative draft and agree for the
most part with its conclusions. I have one doubt about
section 2.1, step 5. where it says:

>   5.  At some point in the (very) distant future, IPv6 connectivity is
>       sufficiently ubiquitous that IPv4 connectivity becomes
>       unnecessary.  At this point, businesses independently remove
IPv4
>       from the network as being no longer useful."

If and when we reach such a point in the (very) distant future, it
seems safe to say that *applications* would cease to use IPv4 but I
wonder if we can safely predict that businesses would remove IPv4 from
their *networks*? I.e., it seems conceivable that IPv4 might remain
in networks for some time (perhaps even indefinitely) after
applications cease to use IPv4.
