Dave,


New paper on Japan's IPv6 policy from GLOCOM's Hajime Yamada and
Nobuo Ikeda (RIETI)

See <http://www.glocom.org/tech_reviews/tech_bulle/20020227_s2/index.html>

They recommend that the Japanese government should not use government
funds to promote IPv6, implementation should be by the private sector.

Comments, which would be very welcome, can be sent to <yamada () glocom ac jp>

Thank you,

Adam


Synopsis
The "e-Japan Priority Policy Program" announced by the Japanese
government has named, as one of its policy targets, the promotion of
Internet Protocol version 6 (IPv6). The reason, it states, is because
the IP addresses (IPv4) currently being used will soon run out. The
authors believe this assumption to be very dubious. Actually, more
than half of the addresses remain unused, and only three percent of
all addresses have been used through connections with the Internet.
It is likely that 15 years from now, some segments of addresses will
still remain unused, and the effective use of unused addresses will
enable almost unlimited use. A virtually infinite number of addresses
can be used under the current IPv4, and it is unlikely that we will
face a shortage. Also, in terms of functions, no important
application has emerged to date that can be used only under IPv6, and
it is doubtful that IPv6 is an essential technological innovation to
deal with issues peculiar to the age of broadband communications. It
is meaningless to rush to commercialize IPv6 under the current
circumstances. Moreover, hasty attempts by the national government to
promote it could hinder the healthy development of the Internet.
