If you're specifying requirements for a closed network in which you are not mixing other devices (i.e. ones that might use real UUIDs), I am not sure I/we can say much. But if this is an open network where a mix of clients operate (or might in the future), I would be against doing this. Again, use DUID-EN in that case (the 4-6 extra bytes should not be an issue - you don't necessarily need the 2-byte type or you could even use a 1-byte type or no type; you can always get a new enterprise-id if you need a different format in the future). - Bernie -----Original Message----- From: dhcwg <dhcwg-bounces@ietf.org> On Behalf Of Templin (US), Fred L Sent: Friday, January 15, 2021 1:57 PM To: Bob Hinden <bob.hinden@gmail.com> Cc: dhcwg <dhcwg@ietf.org>; IPv6 List <ipv6@ietf.org>; Dickson (US), Sean M <sean.m.dickson@boeing.com> Subject: Re: [dhcwg] [EXTERNAL] Re: I-D Action: draft-templin-duid-ipv6-01.txt To everyone who has commented, this is the particular exchange for which I have been expecting but have not received follow-up discussion on the answer I provided. I will not answer any more questions, because I would simply be reiterating the same answer I provided in this exchange below. If I get no follow-discussion (especially from Bob Hinden) I will consider the DUID-V6ADDR idea "dead" and revert to using DUID-UUID to encode 128-bit values of all types *even if they are not UUIDs*.
