The Current Status of IPv6

IPv6 commercial ISP operational status in Japann IX(internet eXchange) for IPv6

w NSPIXP6･･･IPv6 only: since Sep/1999w NSPIXP2･･･IPv6/v4 Dual stack: since Apr/2001

n ISP IPv6 Commercial Servicew IIJ (since Sep/1999)w NTT Communications OCN (since Dec/1999)w KDDI (since Oct/2000) etc…

IPv6 router development statusn Basic routing protocol (IGP, EGP) is available.n Some performance problemn SNMP/MIB and some operational technology is advancing to

standardization.
