I am an assigned INT directorate reviewer for < https://tools.ietf.org/html/draft-ietf-6lo-privacy-considerations-03 >. These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see http://www.ietf.org/iesg/directorate.html . This document is very well written and looks useful. I didn't find any obvious technical issues that may block publication. One possible point that my warrant a discussion is that this document doesn't seem to be very specific to resource constrained nodes (as the title and abstract suggests). I don't see anything tightly specific to such nodes except for some parts of Section 3. Even in Section 3 most of the discussions seem generic. I wonder whether such general privacy issues regarding IPv6 addresses are already covered by some existing documents. If so, this document could be much shorter by just referring to such documents and focusing on a few points specific to 6lo nodes. If not, we might rather consider publishing it as such a generic document. -- JINMEI, Tatuya
