CERNET IPv6 History

May 3, 1998, IPv6 on FreeBSD at Tsinghua University

Sept. 1998 first BGP4+ peer to Sprint (MRTd)

Nov. 1998, First 6Bone backbone node in China

Mar., 2000 IPv6 BBS--6th Galaxy opened

April 26, 2000 obtained sTLA (2001:250::/35 ) from APNIC

Aug., 2000《 IPv6原理与实践》 published

Sep. 25, 2000 CERNET joined IPv6 Forum

Jan. 2002 DRAGONTAP IPv6 IX is running

Jun. 2002 NSFCNET double stack is running

Sept. 2003 CERNET2 test nodes are running
