RFC 6547: RFC 3627 to Historic Status 💖

  • Series and number: Internet Engineering Task Force (IETF) Request for Comments 6547 🎀
  • Author: W. George (Wesley George), Time Warner Cable 🫶
  • Date: February 2012 🌸
  • Category: Informational, so this one is published for information and is not a Standards Track spec 📚
  • Obsoletes: 3627 🙈
  • Updates: 6164 ✨
  • ISSN: 2070-1721

Abstract ✨

okay so this doc moves "Use of /127 Prefix Length Between Routers Considered Harmful" (RFC 3627) over to Historic status 🕰️ because the newer guidance in "Using 127-Bit IPv6 Prefixes on Inter-Router Links" (RFC 6164) has replaced it. A Standards Track doc beats an informational one, so if the two ever clash, RFC 6164 wins 👑. This doc just links the two RFCs together so everyone can see where the IETF's current advice on this topic lives 💅.

Status of This Memo 📝

this document is not an Internet Standards Track specification 🙅‍♀️. it's published for informational purposes 🧚.

this document is a product of the Internet Engineering Task Force (IETF) 🌈. it represents the consensus of the IETF community and has received public review. it was approved for publication by the Internet Engineering Steering Group (IESG). not every doc the IESG approves is a candidate for any level of Internet Standard, so see Section 2 of RFC 5741 for that 🔍.

1. Introduction 🌟

okay so this doc moves "Use of /127 Prefix Length Between Routers Considered Harmful" [RFC3627] to Historic status, following RFC 2026 [RFC2026] 📖. RFC 3627 has been superseded by "Using 127-Bit IPv6 Prefixes on Inter-Router Links" [RFC6164] 🔄. again, a Standards Track doc supersedes an informational one, so guidance in RFC 6164 is to be followed whenever the two conflict ⚖️.

this might not be obvious to casual readers who don't know the difference between IETF document types 🙈. so this doc adds the missing link between the two RFCs. that way, anyone who looks up RFC 3627 for guidance will see that it's been obsoleted by newer guidance on the topic 💅. the hope is that this clears up any confusion 🫶.

2. Security Considerations 🔐

this document introduces no new security considerations 🙌.

3. Acknowledgements 🎀
