Shin Miyakawa-san, thanks for the reply; to see such widespread adoption
of IPv6 in Japan is motivating.

What kind of addresses are delivered?
Please look at RFC4241.
Looked at it. It says mainly PPPv6 and DHCPv6 prefix delegation. For
our discussion here that sounds as supportive argument for DHCP, PPP and
IPv6. It doesn't say PANA.
Actually, we've modified a bit in addition to this model.
Basically, we've added RA onto the uplink between CPE and Access Concentrator
because of some operating system like Windows Vista uses the strong model
for its network design.
If I could have a chance, I am grad to tell about our architecture
in Vancouvor in some proper place.
To me it sounds as a nice presentation slot for one of the IPv6 or DHC
related working groups. But probably this has already been presented.
I'm talking from a 2001 experience of actually picking up the phone and
calling NTT and asking them for IPv6 access.
All these things are important in order to really answer the question
raised above.
It may all be in that 'residential' keyword. How much 'residential' is
a SOHO? What does 'residential' really mean in Japanese?
SOHO as well as just an apartment or house.
One my house in Tokyo had been equipped with residential IPv6/v4 dual ADSL
service from my own company.
I believe that this is residential :-)
(Now I personally am using FTTH service from NTT as well with IPv6
softwire commercial service on it.)
I'm happy to see this at IETF.
FTTH (Fiber-To-The-Home) supporting IPv6 is interesting too. Is there a
IPv6-over-FTTH document somewhere?
