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
