A new Request for Comments is now available in online RFC libraries. RFC 6752 Title: Issues with Private IP Addressing in the Internet Author: A. Kirkham Status: Informational Stream: IETF Date: September 2012 Mailbox: tkirkham@paloaltonetworks.com Pages: 14 Characters: 31838 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-grow-private-ip-sp-cores-07.txt URL: http://www.rfc-editor.org/rfc/rfc6752.txt The purpose of this document is to provide a discussion of the potential problems of using private, RFC 1918, or non-globally routable addressing within the core of a Service Provider (SP) network. The discussion focuses on link addresses and, to a small extent, loopback addresses. While many of the issues are well recognised within the ISP community, there appears to be no document that collectively describes the issues. This document is not an Internet Standards Track specification; it is published for informational purposes. This document is a product of the Global Routing Operations Working Group of the IETF.
