(Note: If you are just starting to think about deploying Internet Protocol version 6 (IPv6) or are still in the pre-planning phases of an IPv6 deployment, please review the Before you Begin article in the Deployment section. This will help you better understand the information provided by this article.)

No attempt has been made to extract lessons learned. Instead, original documents are referenced so that the lessons learned and any best practices they offer can be understood in context. Through intentional reuse, lessons learned can become best practices.

This Overview of Lessons Learned article contains five major topics:

  1. Organization lessons learned from countries around the world,
  2. Defense Research and Engineering Network (DREN) IPv6 Pilot lessons learned summaries
  3. DREN IPv6 Pilot lessons learned details,
  4. Recipients of DREN IPv6 Pilot lessons learned, and
  5. Lessons learned from protocol transitions prior to IPv4.

1. Organization lessons learned. Materials listed below come from a wide variety of sources, including conference presentations, research papers, industry studies, commercial provider publications, and news media. These materials are grouped into ten subtopics:

  1. United States (US) Department of Defense (DoD) Organizations
  2. Other US Federal government Organizations
  3. Networking Customers
  4. Networking Service Providers
  5. Academic Community
  6. Standards Developing Organizations
  7. Non-commercial Organizations
  8. European and Asian IPv6 Communities
  9. Australian IPv6 Community
  10. The Small Office/Home Office (SOHO)

The IPv6 Network Testing Results article in the Testing section provides lessons learned while testing IPv6 networks.

Note: The European 6NET project reported lessons learned by several colleges and universities along with networking customers and networking service providers of all sizes. The 6NET project completed Jun 2005, followed by the 6DISS project which completed Sept 2007; followed by 6DEPLOY and 6DEPLOY-2 (www.6deploy.eu) which completed Feb 2013. A more recent European IPv6 project was Governments Enabled with IPv6 (GEN6), which completed May 2015. Deliverables and Presentations under the Publications tab of the GEN6 website provide additional material. The current European IPv6 project is IPv6 Framework for European Governments.

2. DREN IPv6 Pilot lessons learned summaries. If you want to discover the lessons learned by the DREN IPv6 pilot during the 2003 through 2014 time period, without having to read through the detailed articles that comprise the majority of the IPv6 Knowledge Base, you have four choices:

  • This presentation and accompanying whitepaper provides an executive overview of the DREN IPv6 Pilot. They describe challenges overcome by the DREN IPv6 Pilot.
  • This article provides a mid-level review of the DREN IPv6 Pilot and lessons learned during its deployment of IPv6: DREN IPv6 Pilot — 3 years of IPv6 in the real world. This covers the history, organization, processes, and results of the DREN IPv6 Pilot as of 2006. It discusses the reasons for the success of the DREN IPv6 Pilot, and provides some details (elapsed time, hours, dollars, training) for how “success” was measured (metrics). If you are really in a hurry and only have time to look at a couple of slides, then look at slides 44-47.
  • This presentation provides a mid-level assessment of the DREN IPv6 Pilot lessons learned as of 2014.
  • In a series of briefings started in 2005 and continuing through 2012, more specific technical lessons learned summaries have been presented at the Internet2 Joint Techs workshops. Those briefings are available here in the “Various Presentations” section of the DREN IPv6 Backbone website (archived 2012).

3. IPv6 lessons learned details. The six sections that follow the Deployment section (IP Transport, Infrastructure, Network Management, Security, Applications, and Testing) contain articles providing more detailed descriptions of the lessons learned by DREN as well as by numerous other organizations while deploying IPv6, together with informal guidelines and aides to help in deploying IPv6.


4. Recipients of DREN IPv6 Pilot lessons learned. Lessons learned have been provided by the DREN IPv6 Pilot to other organizations through conference presentations, participation in numerous DoD, Service, and other Federal organizations' working groups, and in response to questionnaires received from commercial companies and Federal organizations.


5. Lessons learned from protocol transitions prior to IPv4. Networks used other protocols prior to IPv4. A comprehensive summary of lessons learned during earlier protocol transitions was provided by Tony Hain here. Two important IETF RFCs specific to the transition to IPv4 are RFC 801 ”NCP/TCP Transition Plan” and RFC 942 “Transport Protocols for Department of Defense Data Networks.” They discuss basic issues and provide a few warnings against tempting shortcuts. A retrospective article on the shortcomings of the Network Control Protocol (NCP) is available. (Caution: Published on April Fools' Day, 2011!).
