[ipv6hackers] Fwd: Generation/Selection of IPv6 addresses by DHCPv6 servers (Fwd: New Version Notification for draft-gont-dhcwg-dhcpv6-iids-00.txt)

[Fernando Gont]

Hi, all,

Heads up. This aligns with other work a number of us have been doing in 
this area, such as RFC7721, RFC7707, and RFC9416.

Feedback welcome!

Thanks,
Fernando

Hi, all,

I recently happened to run into draft-ietf-dhc-rfc8415bis-07, and was 
glad to find that it does provide some advice regarding the generation 
of IPv6 addresses by DHCP6 servers. (Coincidentally or not, this is 
aligns with the recent work in RFC9416 regarding transient numeric 
identifiers).

In that regard, I've posted this I-D (draft-gont-dhcwg-dhcpv6-iids):

  * URL: https://www.ietf.org/archive/id/draft-gont-dhcwg-dhcpv6-iids-00.txt
  * HTMLized: 
https://datatracker.ietf.org/doc/html/draft-gont-dhcwg-dhcpv6-iids

with the goal of producing a Standards Track specification of the 
algorithm in RFC7943, such that it can be better referenced (or 
recommended, as noted in RFC9416) in future revisions of the DHCPv6 spec 
(no, I'm not meaning the current  draft-ietf-dhc-rfc8415bis effort, but 
future ones).

Feedback will be welcome!

Thanks,
Fernando

Name:     draft-gont-dhcwg-dhcpv6-iids
Revision: 00
Title:    A Method for Generating Semantically Opaque IPv6 Interface 
Identifiers (IIDs) with Dynamic Host Configuration Protocol for IPv6 
(DHCPv6)
Date:     2025-02-10
Group:    Individual Submission
Pages:    11
URL: https://www.ietf.org/archive/id/draft-gont-dhcwg-dhcpv6-iids-00.txt

Abstract:

    This document describes a method for selecting IPv6 Interface
    Identifiers that can be employed by Dynamic Host Configuration
    Protocol for IPv6 (DHCPv6) servers when leasing non-temporary IPv6
    addresses to DHCPv6 clients.  This method is a DHCPv6 server-side
    algorithm that does not require any updates to the existing DHCPv6
    specifications.  The aforementioned method results in stable
    addresses within each subnet, even in the presence of multiple DHCPv6
    servers or DHCPv6 server reinstallments.  It is a DHCPv6 variant of
    the method specified in RFC 7217 for IPv6 Stateless Address
    Autoconfiguration (SLAAC).
