At the 6man WG meeting in Dallas there was discussion on what to do (if anything) about duplicate address detection.  The background on this is documented in https://datatracker.ietf.org/doc/draft-yourtchenko-6man-dad-issues/

Should we work on the robustness and efficiency issues of DAD?  For example, improving DAD in environments where nodes sleep and on links with high packet loss.  We think that DAD robustness and efficiency are intertwined and we need solutions that take both into account.

In case the WG wants to address these issues, there is an outline of how they can be addressed in https://datatracker.ietf.org/doc/draft-nordmark-6man-dad-approaches/.  This is probably not the only way they can be addressed, but the draft indicates that the issues are solvable.

The chair would like your feedback on this issue and if there is interest we will schedule an agenda slot in Prague.
