The IESG has received a request from the IPv6 Maintenance WG (6man) to consider the following document: - 'Significance of IPv6 Interface Identifiers' <draft-ietf-6man-ug-05.txt> as Proposed Standard 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 2013-11-28. 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 The IPv6 addressing architecture includes a unicast interface identifier that is used in the creation of many IPv6 addresses. Interface identifiers are formed by a variety of methods. This document clarifies that the bits in an interface identifier have no meaning and that the entire identifier should be treated as an opaque value. In particular, RFC 4291 defines a method by which the Universal and Group bits of an IEEE link-layer address are mapped into an IPv6 unicast interface identifier. This document clarifies that those two bits are significant only in the process of deriving interface identifiers from an IEEE link-layer address, and updates RFC 4291 accordingly. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-6man-ug/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-6man-ug/ballot/ No IPR declarations have been submitted directly on this I-D.
