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.

1. Introduction
The goal of this document is to define the common functionality
required from both IPv6 hosts and routers. Many IPv6 nodes will
implement optional or additional features, but this document
summarizes requirements from other published Standards Track
documents in one place.
This document tries to avoid discussion of protocol details, and
references RFCs for this purpose. This document is informational in
nature and does not update Standards Track RFCs.
Although the document points to different specifications, it should
be noted that in most cases, the granularity of requirements are
smaller than a single specification, as many specifications define
multiple, independent pieces, some of which may not be mandatory.
As it is not always possible for an implementer to know the exact
usage of IPv6 in a node, an overriding requirement for IPv6 nodes is
that they should adhere to Jon Postel's Robustness Principle:
Be conservative in what you do, be liberal in what you accept from
