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 document does two IANA allocations, one for the reserved IPv6 interface identifier for Proxy Mobile IPv6 and another for the reserved IANA Ethernet unicast address for the Proxy Mobile IPv6. The security considerations section points to the Proxy Mobile IPv6 RFC (RFC5213) and Reserved IPv6 Interface Identifiers RFC (RFC 5453) saying there is no additional security considerations known at this point of time beyond them. Only thing that seems bit odd, that there is no obvious point where the allocated reserved IANA values would be inserted, so I do not know whether the final values will be put to the RFC or whether users of them need to go to the IANA registries to find the values. If users are required to find the values from the IANA registries, adding direct pointer to the registry might be useful. -- kivinen at iki.fi
