An IPv6 update – NTP, DHCPv6 and connectivity

I wanted to post a few IPv6 updates since my last post.

The NTP pool project has been working to add IPv6 support for some time. This month, they’ve added partial IPv6 support. Hopefully by year’s end they’ll have full IPv6 support. Several OSes and NTP appliances already have IPv6 support, so there’s a fair bit of infrastructure that could support this now.

Speaking of NTP, the IETF’s NTP working group is working to define IPv6 NTP options for DHCPv6. The current draft of that spec has received some criticism, claiming that its redundant with the current SNTP option. I hope that is resolved at the next IETF meeting in a few months.

Speaking of DHCPv6, Microsoft has fixed several DHCPv6 bugs in the beta of Windows Server 2008 R2. This should significantly improve interoperability with Unix/Linux clients.

Several North American universities and R&E networks obtained IPv6 allocations in 2008. I pulled the list of allocations from ARIN and noticed some highlights:

* Arkansas Research and Education Optical Network
* Bryant University
* Bucknell University
* California Institute of Technology
* California Polytechnic State University
* Florida LambdaRail
* Furman University
* George Mason University
* Louisiana State University
* Lousiana Optical Network Initiative (LONI)
* National Center for Supercomputing Applications
* New York University
* Oregon State University
* Rutgers University
* South Dakota Board of Regents
* Stanford University
* Tufts University
* University of Alaska
* University of California, Irvine
* University of California, Office of the President
* University of California, San Diego
* University of California, Santa Barbara
* University of California, Santa Cruz
* University of Illinois
* University of Iowa
* University of Nebraska-Lincoln
* University of Pennsylvania
* University of Pittsburgh
* University of South Florida
* University of Wisconsin Madison
* Wheaton College
* Worcester Polytechnic Institute

Several of these allocations are already in use. goes IPv6

Last week IANA processed a request to add AAAA records for one of the thirteen DNS root-servers., operated by ICANN, became the seventh of the root servers to have it’s IPv6 address records (AAAA) added into the DNS root-zone. The addition of IPv6 service is part of ICANN’s ongoing commitment to act as a leader in enabling IPv6 services throughout the DNS.

Hurricane Electric Achieves IPv6 Milestone

Hurricane Electric, an international IPv4 and IPv6 Internet backbone, has become the first network in the world to connect over 300 IPv6 networks. IPv4 addresses will run out by 2011. Hurricane Electric has been working diligently to move IPv6 into the forefront so this fact won’t become a crisis. As part of this forward thinking push, Hurricane Electric has been running dual-stack IPv6 and IPv4 at all its locations worldwide.

IPv6 Task Force Scotland Has Been Launched

Scotland/Luxembourg, July 14th, 2008 – The IPv6 Forum welcomes Scotland as its newest member with the establishment of IPv6 Task Force Scotland under the leadership of Dr. David Holder, Chair, IPv6 Task Force Scotland.

The prime objective of the IPv6 Task Force and its members is to promote deployment and swifter uptake of the new Internet using the new Internet Protocol version 6 (IPv6) with support from industry, education, research communities and government agencies enabling equitable access to technology and knowledge,

“The IPv6 Task Force Scotland will try to win key Scottish stakeholders to design an IPv6 Roadmap and create momentum in deploying IPv6 in view of the call of the EU to swiftly adopt IPv6 by 2010″ said Mr. Latif Ladid, IPv6 Forum President.

“The Scottish IPv6 Task Force has very good access to key players from government, industry and academia to coordinate an action plan in view of the imminent integration of IPv6 and deployment in Scotland ” said Dr. David Holder, Chair, IPv6 Task Force Scotland.

The Internet World has been using the Internet Protocol version 4 (IPv4) for the last two decades. Despite its tremendous success, IPv4 is showing signs of strain especially in its fast depleting IP address space and its growing security concerns. IPv6 preserves everything good in today’s Internet, and adds much more, such as virtually unlimited IP address space to connect everyone and everything, stateless auto-configuration, seamless mobility, mandated security and new optional service levels.

About the IPv6 Task Force Scotland

The IPv6 Task Force Scotland is a chapter of the IPv6 Forum dedicated to the advancement and propagation of IPv6 in Scotland. Its mission is to provide technical leadership and innovative thought for the successful integration of IPv6 into all facets of networking and telecommunications infrastructure, present and future.

About the IPv6 Forum

The IPv6 Forum is a world-wide consortium of international Internet service providers (ISPs) and National Research & Education Networks (NRENs), with a mission to promote IPv6 by improving market and user awareness, creating a quality and secure New Generation Internet and allowing world-wide equitable access to knowledge and technology. The key focus of the IPv6 Forum today is to provide technical guidance for the deployment of IPv6. IPv6 Summits are organized by the IPv6 Forum and staged in various locations around the world to provide industry and market with the best available information on this rapidly advancing technology.

IPv6 Samba 3.2 Released Today

Samba 3.2 was released today (1st July 2008). Samba 3.2 is the first production version of the popular open source Windows integration product to fully support IPv6.

Erion was instrumental in the development of an IPv6 enabled version of Samba. Erion’s David Holder carried out a number of firsts with the development version of Samba 3.2, including the first ever join of Samba to a Windows Server 2008 Active Directory domain over IPv6.

Further information on Erion’s involvement with Samba and IPv6 can be found in the these blog posts.
