For fifteen years, we've been hearing that IP version 4 was about to run out of addresses and IPv6 was about to replace it. Today, IPv4 address are indeed within a couple of years of running out. Is IPv6 ready and what are ISPs doing about it? The reality is that we face an indefinite period of IPv4/IPv6 interworking, and this will affect everybody, not just networking specialists. The seminar will address the latest developments in the IETF and present some results from
a recent survey of ISP experience and plans for IPv6.


Brian E. Carpenter joined the University of Auckland in September 2007. He was appointed Professor in January 2009 (with a part-time appointment).

Before that, he spent ten years with IBM at various locations, working on Internet standards and technology. From 1997 he was at IBM\'s Hursley Laboratory in England. From 1999 to 2001 he was at iCAIR, the international Center for Advanced Internet Research, sponsored by IBM at Northwestern University in Evanston, Illinois. He was most recently based in Switzerland as a Distinguished Engineer and a member of the IBM Academy of Technology.

Before joining IBM, he led the networking group at CERN, the European Laboratory for Particle Physics, in Geneva, Switzerland, from 1985 to 1996. This followed ten years\' experience in software for process control systems at CERN, which was interrupted by three years teaching undergraduate computer science at Massey University in New Zealand.

He holds a first degree in physics and a Ph.D. in computer science, and is a Chartered Engineer (UK). He has been an active participant in the Global Grid Forum, and in the Internet Engineering Task Force (IETF), where he has worked on IPv6 and on Differentiated Services. He has also worked with the CERN Openlab for Datagrid Applications. He served from March 1994 to March 2002 on the Internet Architecture Board, which he chaired for five years. He also served as a Trustee of the Internet Society, and was Chairman of its Board of Trustees for two years until June 2002. He was Chair of the IETF from March 2005 to March 2007.
