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. Summary This is just a URN registration, with no relevant security considerations. Details To prevent "URN squatting", I would recommend to include an explanation why a name that's not trivially associated with "Broadband Forum" is claimed here, namely "dslforum-org". Although 2 minutes of research suffice to find the answer. Thanks, Yaron
