Kirkham Internet-Draft Palo Alto Networks Obsoletes: None (if approved) July 30, 2012 Intended status: Informational Expires: January 31, 2013 Issues with Private IP Addressing in the Internet - draft-ietf-grow-private-ip-sp-cores-06 + draft-ietf-grow-private-ip-sp-cores-07 Abstract The purpose of this document is to provide a discussion of the potential problems of using private, RFC1918, or non-globally- routable addressing within the core of an 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.
