Japanese Market UpdateWhy IPv6 in Japan?
• IPv4 address– Not enough IPv4 address space assigned to
Japan and other Asian countries
• IT Growing Rapidly– Always On– Mobile– Consumer Electronics Products
• Japan needs more IP address!

Problems Caused By Scarcity of IP addresses
Company/Campus
Carrier/ ISP
Solutions in last 5 years
・ Using private IP addresses for intranet
・ Translate global IP address, when internal hosts access to external WWW servers.
・ Temporary assignment of IP addresses to users, when the session is linked up.
・ Using private IP addresses and NAT
Current Issues
・ VPN construction is difficult, because NAT is unidirectional ( “private” to “global”)
・ Duplication of IP addresses, on merger etc.
・ Application restriction (e.g. ftp isn’t available)
・ Increasing operational administrative costs・ Semi-static address assignment because of
permanent connection services
・ Difficulty to service as users, hosts and network equipment increases
・ Increasing operational/administrative costs
Ad-hoc methods (e.g. NAT) has been used to resolve scarcity of IP addresses in last 5 years.
However, issues such as duplication of private IP addresses , restriction on applications, etc. still exist.
