I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written primarily for the benefit of the security area directors. Document editors and WG chairs should treat these comments just like any other last call comments. This five page document clarifies that the intent of the term "global" in RFC 6809 is for a special-purpose address to be "globally reachable". It also corrects some errors in the IANA Special-Purpose Address Registries. Since the scope of "global" is clarified rather than changed, there does not seem to be any additional security considerations. None of the error corrections introduce additional security considerations either. The authors obviously came to the same conclusion since they did not include a Security Considerations section. This does not concern me personally, and I'll leave it for the Security ADs to determine if they prefer one added that states "there are no security considerations". I consider the document Ready.
