That's the network layer, not the transport layer. IPv6 scoping has the
potential to be very helpful for private addressing since it's fundamentally
built into the protocol, as opposed to RFC1918 addresses which are just
kinda an afterthought. This means that, by default, vendor products should
DTRT with respect to scoped addresses, and administrators have more
Unless I am out hiking completely, you are talking about site-locals.
Please don't: They are no more -- the ipv6 session at the SF IETF
reached in-room consensus about removing them, a decision that was
later confirmed on the mailing list. There are people who did not
like this, and they rather loudly try to get the decision reversed,
but they are the minority.
Site-locals are, thank $DEITY, a thing of the past.
(OTOH, Link-locals still remain in the protocol.)
Without trying to find the mailing lists for the IPv6 working groups,
this must have been pretty recent. I just check up on RFCs every once
in a while and RFC 3513, dated April 2003, still talks about Site-Local.
RFC 3587, from this month, talks about losing Top Level Aggregators
and Next Level Aggregators, but that's something different.
I don't doubt you though, even though it's being deployed, IPv6 is far
from completely specified. The details still move around faster than
I'll be followoing. Heck, no one really has found a good way to use the
DIFSERV fields of IPv4 yet.
