Simple Procedures for Detecting Network Attachment in IPv6
Abstract
Detecting Network Attachment allows hosts to assess if its existing
addressing or routing configuration is valid for a newly connected
network. This document provides simple procedures for Detecting
Network Attachment in IPv6 hosts, and procedures for routers to
support such services.
