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 informational draft discusses requirements for a IP replacement of AppleTalk's Name Binding Protocol (NBP). As an individual submission, there is likely little value in commenting on the content. However, I would have appreciated if the authors would have discussed security as a requirement for an NBP replacement. I know that flexible discovery is often pretty much as odd with security, having "security measures appropriate to the environment in which" an NBP replacement "will be used" could have been an explicit requirement. Editorial nit: On page 9, the DNS name "printer1.ietf.org" should probably changed to "printer1.example.com". /js -- Juergen Schoenwaelder Jacobs University Bremen gGmbH Phone: +49 421 200 3587 Campus Ring 1, 28759 Bremen, Germany Fax: +49 421 200 3103 < http://www.jacobs-university.de/ >
