US DoD and IPv6

2010-09-27 18:32:05
So, I came across a interesting recent (June 24, 2010) article on the US
DoD's news site (, which quote Kris Strance,
"the chief of internet protocol for the [Dod]", as saying:

  "{the DoD} philosophy is one that when a component has a mission need or a
  business case to move to IPv6, then they can do that ... It's driven by
  their need rather than an overall [Department of Defense] mandate."

(The complete article is at:

This seems a significant change in course from that given in the "Internet
Protocol Version 6 (IPv6) Interim Transition Guidance" of September 29, 2003,
which said that:

  "the DoD has established the goal of transitioning all DoD networking to
  the next generation of the Internet Protocol, IPv6, by fiscal year (FY)

The date slippage is not a big deal, I'm ignoring that. What is of more
interest is that it appears (from the news story) that there has been a
further* change of course on IPv6 adoption, from 'we _are_ going to
transition' to 'in cases where there is a monetary or operational case to
convert, it will happen, but otherwise not'.

Can anyone shed any light on this apparent change in policy?



* The only other policy course change I am aware of is the one from August
16, 2005 ("Internet Protocol Version 6 (IPv6) Policy Update"), which said

  "... waiver submissions for programs not transitioning to IPv6 by FY2008.
  Henceforth, IPv6 waivers are not required by DoD CIO policy."

(The original September 29, 2003 policy had said "If the IPv6 capable
criteria {for any DoD acquistion} cannot be met, a waiver will be required.")

I suppose that technically the seeming current course fits within that updated
policy, but it still seems to be a change in emphasis and direction.
