IPv6 Subnet Model: The Relationship between Links and Subnet Prefixes

Overview

RFC 5942, “IPv6 Subnet Model: The Relationship between Links and Subnet Prefixes”, is a Proposed Standard document published in July 2010 by H. Singh, W. Beebee, E. Nordmark. It updates RFC 4861. The canonical text is published by the RFC Editor.

Abstract

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]

Abstract as published in the RFC, via rfc-editor.org.

What “Proposed Standard” means

An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
