IPv6 Node Requirements
draft-ietf-6man-rfc6434-bis-00
Abstract
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.
This document obsoletes RFC 6434, and in turn RFC 4294.
