Hello group,

I updated version -01 of the Homenet prefix assignment draft.

Changes since -00 are:
- Add a paragraph specifying that Route Information Options must be included in router advertisements, providing in-home prefixes information.
- Lost Delegated Prefixes are advertised up to 2 hours (In agreement with SLAAC and RFC7084).
- Deprecated Delegated Prefixes (preferred lifetime = 0) are not used for new assignments (Unless configuration states otherwise or no other prefix is available).
- New **proposal** for autonomously generated ULAs. If no IPv6 prefix is available, ULA generation is a ‘SHOULD’. The proposition also deals with network splits.

Please notice that the change concerning the ULA generation is a hot topic. 
This is a proposal, trying to provide a solution to the different concerns expressed on the dedicated thread:

Comments are welcome.


- Pierre

> Abstract:
>   This memo describes a home network prefix and address assignment
>   algorithm running on top of any 'flooding protocol' that fulfills the
>   specified requirements.  It is expected that home border routers are
>   allocated one or multiple IPv6 prefixes through DHCPv6 Prefix
>   Delegation (PD) or that prefixes are made available through other
>   means.  An IPv4 address can also be assigned and private addresses be
>   used with NAT to provide IPv4 connectivity.  In both cases, provided
>   prefixes need to be efficiently divided among the multiple links, and
>   routers need to obtain addresses.  This document describes a
>   distributed algorithm for IPv4 and IPv6 prefixes division, assignment
>   and router's address assignment, and specifies how hosts can be given
>   addresses and configuration options using DHCP or SLAAC.
> Please note that it may take a couple of minutes from the time of submission
> until the htmlized version and diff are available at tools.ietf.org.
