Using 127-Bit IPv6 Prefixes on Inter-Router Links
RFC 6164, “Using 127-Bit IPv6 Prefixes on Inter-Router Links”, is a Proposed Standard document published in April 2011 by M. Kohno, B. Nitzan, R. Bush, Y. Matsuzaki, L. Colitti, T. Narten. It has since been updated by RFC 6547. The canonical text is published by the RFC Editor.
Abstract
On inter-router point-to-point links, it is useful, for security and other reasons, to use 127-bit IPv6 prefixes. Such a practice parallels the use of 31-bit prefixes in IPv4. This document specifies the motivation for, and usages of, 127-bit IPv6 prefix lengths on inter-router point-to-point links. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
