A new Request for Comments is now available in online RFC libraries. RFC 5942 Title: IPv6 Subnet Model: The Relationship between Links and Subnet Prefixes Author: H. Singh, W. Beebee, E. Nordmark Status: Standards Track Stream: IETF Date: July 2010 Mailbox: shemant@cisco.com, wbeebee@cisco.com, erik.nordmark@oracle.com Pages: 11 Characters: 27035 Updates: RFC4861 I-D Tag: draft-ietf-6man-ipv6-subnet-model-12.txt URL: http://www.rfc-editor.org/rfc/rfc5942.txt IPv6 specifies a model of a subnet that is different than the IPv4 subnet model. The subtlety of the differences has resulted in incorrect implementations that do not interoperate. This document spells out the most important difference: that an IPv6 address isn't automatically associated with an IPv6 on-link prefix. This document also updates (partially due to security concerns caused by incorrect implementations) a part of the definition of "on-link" from RFC 4861. [STANDARDS TRACK] This document is a product of the IPv6 Maintenance Working Group of the IETF. This is now a Proposed Standard Protocol. 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.
