Technical Summary This document describes a protocol for asking an IPv6 node to supply certain network information, such as its hostname or fully-qualified domain name. IPv6 implementation experience has shown that direct queries for a hostname are useful, and a direct query mechanism for other information has been found useful in serverless environments and for debugging. Working Group Summary The latest specification does differ from what is currently deployed. Reviews revealed that the multicast prefix used by the Node Info Queries does not conform to the requirements of RFC 3307. The editors corrected the oversight within the specification to ensure proper operation over the long-term. Those who have already implemented the protocol agreed with the change and plan on updating their code to conform to the new multicast prefix. Other minor changes were made to address deprecated functionality that no longer needs to be supported (e.g. IPv4-compatible addresses and site-local addresses). Protocol Quality IPv6 Node Information Queries have been widely implemented in the ping6 program in the KAME (<http://www.kame.net>), USAGI, and other IPv6 implementations. It is proved to be very useful when debugging problems or when bringing up IPv6 service where there isn't global routing or DNS name services available. IPv6's large auto- configured addresses make debugging network problems and bringing up IPv6 service difficult without these mechanisms.
