<without any hat>

Hello Fred,

Just wondering how would this new DUID could be used when several interfaces sharing the same DUID will request some address(es)/prefix(es) over DHCPv6 ?

If you allow me to guess your use case, then would DUID type based on the private enterprise number (FAA and EASA have ones) could be used ? This would be simpler than requesting a new DUID type

Hope this helps,

Regards

-éric

    Hi, more and more IPv6 address generation methods are being specified that
    intend to generate IPv6 addresses that are highly likely to be unique on either
    a global scale or unique within a bounded service domain. So much so, that
    some address generation methods intend for the IPv6 addresses to be usable
    as node identifiers.

    Recognizing this, this document proposes a new DHCPv6 DUID type known
    as "DHCP-V6ADDR" that includes an IPv6 address in the body of the DUID. In
    this way, IPv6 addresses produced by address generation methods intending
    to generate a node ID can be used as unique identifiers in DHCPv6 message
    exchanges. This would introduce a single new DUID type, for which the IANA
    allocation policy is  "standards action".

    Alternatively, a separate DUID type could be allocated for each IPv6 address
    generation method. However, that approach may result in additional IANA
    allocations and would require implementation updates every time a new
    address generation method is specified. Hence, a single generic DUID type
    for all IPv6 generation methods is proposed, but open for discussion.

    Comments on the list welcome.

    Fred

    A New Internet-Draft is available from the on-line Internet-Drafts directories.


            Title           : The IPv6 Address-based DHCPv6 Unique Identifier (DUID-V6ADDR)
            Author          : Fred L. Templin
    	Filename        : draft-templin-duid-ipv6-01.txt

    	Date            : 2021-01-11

    Abstract:
       This document defines a new DHCPv6 Unique Identifier (DUID) type
       called DUID-V6ADDR that contains a single 128 bit IPv6 address.
       DUID-V6ADDR makes it possible for devices to use suitably-derived
       unique IPv6 addresses to identify themselves to DHCPv6 servers and/or
       other network nodes.
