"Solution approaches for address-selection problems", Arifumi Matsumoto, Tomohiro Fujisaki, Ruri Hiromi, Ken-ichi Kanayama, 1-Jul-09. ( bytes)

In response to address selection problem statement and requirement documents, this document describes approaches to solutions and evaluates proposed solution mechanisms in line with requirements. It also examines the applicability of each solution mechanism from the viewpoint of practical application.

"IPv6 Node Requirements RFC 4294-bis", John Loughney, Thomas Narten, 13-Jul-09. ( bytes)

This document defines requirements for IPv6 nodes. It is expected that IPv6 will be deployed in a wide range of devices and situations. Specifying the requirements for IPv6 nodes allows IPv6 to function well and interoperate in a large number of situations and deployments.

"IPv6 Subnet Model: the Relationship between Links and Subnet Prefixes", Hemant Singh, Wes Beebee, Erik Nordmark, 15-May-09. ( bytes)

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 [RFC4861].

"Handling of overlapping IPv6 fragments", Suresh Krishnan, 2-Jul-09. ( bytes)

The fragmentation and reassembly algorithm specified in the base IPv6 specification allows fragments to overlap. This document demonstrates the security issues with allowing overlapping fragments and updates the IPv6 specification to explicitly forbid overlapping fragments.
