The IESG has received a request from the IPv6 Maintenance WG (6man) to consider the following document: - 'Recommendation on Stable IPv6 Interface Identifiers' <draft-ietf-6man-default-iids-16.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 2016-12-02. 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 changes the recommended default IID generation scheme for cases where SLAAC is used to generate a stable IPv6 address. It recommends using the mechanism specified in RFC7217 in such cases, and recommends against embedding stable link-layer addresses in IPv6 Interface Identifiers. It formally updates RFC2464, RFC2467, RFC2470, RFC2491, RFC2492, RFC2497, RFC2590, RFC3146, RFC3572, RFC4291, RFC4338, RFC4391, RFC5072, and RFC5121. This document does not change any existing recommendations concerning the use of temporary addresses as specified in RFC 4941. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-6man-default-iids/ IESG discussion can be tracked via https://datatracker.ietf.org/doc/draft-ietf-6man-default-iids/ballot/ No IPR declarations have been submitted directly on this I-D.
