I reviewed the document "Host Mobility with the Host Identity Protocol" (draft-ietf-hip-rfc5206-bis-12.txt) as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG.  These comments were written primarily for the benefit of the operational area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.   Intended status: Standards Track                           Updates: 5206 (if approved) Current IESG state: IESG Evaluation IANA OK - Actions Needed   Summary: This document defines mobility extensions to the Host Identity Protocol (HIP) and specifies a general "LOCATOR_SET" parameter for HIP messages that allows for a HIP host to notify peers about alternate addresses at which it may be reached. The document also defines elements of procedure for mobility of a HIP host.   The document is dependent on two other bis-drafts, for which the normative references in section 9.1 are outdated.     == Outdated reference: A later version (-11) exists of      draft-ietf-hip-rfc5203-bis-10     == Outdated reference: A later version (-08) exists of      draft-ietf-hip-rfc5204-bis-07     I don't see any issues related to operations and management.   I think the document is well written and ready to publish.   Mehmet
