Hi, I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments. The draft describes a mechanism by which renumbering of the Home Network Prefix for a set of Mobile Nodes can be supported. In this process it is assumed that serving Local Mobility Anchor(s) are not renumbered. Overall, the document is well-written. Comments: In Section 5, part (3), the document says both Preferred and Valid Lifetime should be set to 0. Certainly the Preferred Lifetime can be set to 0 (to deprecate the prefix for address selection) but can the Valid Lifetime be set below 2 hours? Are the RAs authenticated in this scenario? (see 5.5.3 of RFC 4862, part (e).2). It is good to see documents from the (now closed) 6renum WG being cited (RFC6879 and RFC7010). The document includes RFC2119 requirements language, but then doesn’t seem to use it. Either the Requirements Language section should be removed, or the body should use RFC2119 style terminology. Nits: There are a handful of editorial nits, e.g. “not the type of PI” in Section 1. Otherwise, the document is Ready for publication. Best wishes, Tim
