A new Request for Comments is now available in online RFC libraries. RFC 7136 Title: Significance of IPv6 Interface Identifiers Author: B. Carpenter, S. Jiang Status: Standards Track Stream: IETF Date: February 2014 Mailbox: brian.e.carpenter@gmail.com, jiangsheng@huawei.com Pages: 10 Characters: 23172 Updates: RFC 4291 I-D Tag: draft-ietf-6man-ug-06.txt URL: http://www.rfc-editor.org/rfc/rfc7136.txt 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 it updates RFC 4291 accordingly. This document is a product of the IPv6 Maintenance Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet standards track protocol for the Internet community,and requests discussion and suggestions for improvements. Please refer to the current edition of the Internet Official Protocol Standards (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited.
