Hi All,
Maybe, but I think most Network administrators understand that using
guess-what-I-hijacked addresses is risky. Instead I bet you'll see them
rolling their own NATv6 solutions. It's lot easier for us v4-ish
old-timers to understand than some of what I've read here today :-)

a) they are not the same thing

It's our job to stop that happening.
I agree, and I actually consider our job to be even bigger
than this...
We need to create the technologies and policies that will enable a
globally-addressable, "flat" IPv6 Internet.

Same here for me. I see not advantage at all and lots of pain.

Do you meant to imply that a separate block of addresses should be
set aside for non-globally-routable globally-unique addresses?
I'm not sure what we gain by doing that, as opposed to setting aside
private address space from any global prefix by filtering it at
administrative boundaries...

I think this is a bit too specific - until we produce a good way of
doing renumbering, any site with more than a few hosts has good reason
to want its addresses to be stable, whether or not it thinks it

which is why we need to make it very clear that NAT is not acceptable
in IPv6.

I understand the theoretical issue, but is this a real-life issue?
How many huge non-globally-connected IP networks will ever need to
join the Internet?

It is not. Same problems that NAT has. And loss of e2e: apps,
security, and mobility for those who only have those SLs. Not good.

Hi Brian,
So, why not simply deprecate SL for sites that have at least one
global prefix? Or am I too simple minded?
If you are too simple minded, then I am right there with you.

Hi Tim,
Our "job" is to provide a well-engineered alternative that the
market will demand.
Excellent point, and well put.
