The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-dhc-mac-assign/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- [ Thank you for addressing my DISCUSS, I've cleared.] Thank you for writing this -- I *do* like this document, and agree that it solves a real problem (e.g: http://grouper.ieee.org/groups/802/PrivRecsg/email/msg00164.html ), but would like to make sure that it is deployable without causing sadness... I think it would be useful to also add some text around policy limits / DoS. As examples, would you expect that this would be enabled on "regular" user interfaces (e.g at my local coffee shop), or is it more designed for datacenters and IoT VLANs? Either way, should a device be able to ask for 00:00:00:00:00:01 and 2^48-2 addresses? The document does say things like: "In particular, the server may send a different starting address than requested, or grant a smaller number of addresses than requested.", but it might be nice to also include something like "implementations should allow configuration of the maximum number of addresses to allocate" or something similar (yes, an attacker could keep coming back and looking like a new device, but...)
