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. The draft provides nomenclature of types and type extensions used by Mobile Ad hoc Networking's (MANET) Packet, Message, and Address Blocks. The draft also specifies a corresponding IANA registry for these types. The security considerations section does exist and discloses that the draft does not impose any security considerations in itself. I agree with this assertion. General comments: None. Editorial comments: s/consisteng/consistent/ Shawn. --
