I am an assigned INT directorate reviewer for draft-ietf-dhc-addr-notification. These comments were written primarily for the benefit of the Internet Area Directors. Document editors and shepherd(s) should treat these comments just like they would treat comments from any other IETF contributors and resolve them along with any other Last Call comments that have been received. For more details on the INT Directorate, see https://datatracker.ietf.org/group/intdir/about/ . Based on my review, if I was on the IESG I would ballot this document as YES. I think the document is very well written and I personally find it very useful. The following are minor issues (typos, misspelling, minor text improvements) with the document: - At the end of section 1, it is mentioned that the mechanism described in the document provides parity with IPv4, by allowing a device to inform the DHCPv6 server about a self-configured or statically configured address. Apologies for my ignorance on this in advance, but, is there a mechanism in IPv4 to do so for statically configured addresses? If so, I think adding a reference would be useful. If not, maybe the text can be rewritten a bit, as I would find it a bit unclear. - It is mentioned that the client MUST include the Client Identifier option in the ADDRESS-REG-INFORM messages. I think this might deserve some text regarding how this might imply (or not) a potential privacy issue for hosts implementing some kind of MAC address randomization and rotation of IPv6 self-assigned addresses, as an observer could easily track the addresses being used and match those to the same device. - It is not completely clear to me if the spec requires a client to use the mechanism on ALL interfaces. I mean, can a client use it just on some interfaces, but not all, by having configuration policies indicating on which ones to use it? As I read the document, it seems to imply that if it is used on one interface, it MUST be used on all of them. - Minor nit (or maybe just nothing at it is just that I’m not a native English speaker): “to specify the address to being registered” -> I guess the “to” should be removed.
