The IESG has received a request from the IPv6 Site Renumbering WG (6renum) to consider the following document: - 'IPv6 Site Renumbering Gap Analysis' <draft-ietf-6renum-gap-analysis-05.txt> as Informational RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2013-04-10. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract This document briefly introduces the existing mechanisms that could be utilized for IPv6 site renumbering and tries to cover most of the explicit issues and requirements of IPv6 renumbering. Through the gap analysis, the document provides a basis for future works that identify and develop solutions or to stimulate such development as appropriate. The gap analysis is presented following a renumbering event procedure summary. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-6renum-gap-analysis/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-6renum-gap-analysis/ballot/ No IPR declarations have been submitted directly on this I-D.
