Neighbor Discovery for IP version 6
RFC 4861, “Neighbor Discovery for IP version 6”, is a Draft Standard document published in September 2007 by T. Narten, E. Nordmark, W. Simpson, H. Soliman. It obsoletes RFC 2461. It has since been updated by RFC 5942, RFC 6980, RFC 7048, RFC 7527, RFC 7559, RFC 8028, RFC 8319, RFC 8425, RFC 9131, RFC 9685, RFC 9762, RFC 9926. The canonical text is published by the RFC Editor.
Abstract
This document specifies the Neighbor Discovery protocol for IP Version 6. IPv6 nodes on the same link use Neighbor Discovery to discover each other's presence, to determine each other's link-layer addresses, to find routers, and to maintain reachability information about the paths to active neighbors. [STANDARDS-TRACK]
What “Draft Standard” means
A historical maturity level (retired in 2011) that sat between Proposed Standard and Internet Standard and required multiple interoperable implementations.
