IPv6 is now a mature standard, with the core protocols defined by the Internet Engineering Task Force (IETF). Over the past two years a number of national research networks and academic network backbone providers have deployed IPv6 in production, using dual-stack networking. The challenge ahead now is to push IPv6 deployment into the universities and end sites in the academic networks. This paper presents an overview of the current state of IPv6 transition at one such site, the University of Southampton (UK), drawing on experience gained from participation on the 6NET and Euro6IX projects.
