IPv6 working group has discussed a possibility of using a light-weight
DHCPv6 solution for e.g. DNS configuration, but nothing related to address

I threw up this idea and there was some support for it.  Many people are a 
bit unconfortable with "legacy" parts of DHCPv6, that aren't really all 
that necessary with IPv6.  And these features are the ones that most 
people will not need.

So I see two practical approaches:

 1) separate the draft to:
    a) Dynamic Node Configuration Protocol, which is used for 
Informational Records only (the main specification)
    b) XXX, which is used when one wants the "stateful" parts, e.g. 
address allocation.

   This has the great benefit that when the vast majority of people are
   only interested about a), the base specification would become very 
   simple and relatively short.

   The drawback naturally is that this requires more work..

 2) after publishing the draft as is, later come back and specify
   which parts of the DHCPv6 protocol to implement to get either a).

   This has the drawback that those that are only intrerested about the
   lightweight solution have to go through the whole of DHCPv6, and
   that conceptually separating the two might be difficult.

Needless to say, I'm in the favor of 1); I've never been a big fan of 
the idea behind DHCPv6, but this way I'd find it rather interesting, for 
solving the initial configuration problem.

Subject: Stateless DHCP and the DHCP draft


Would it make sense to consider whether separating "stateless DHCPv6" and
the stateful part (~address assignment) to separate drafts would make

I think a lot more people would be confortable with DHCPv6 if it was very
simple and supported only the informational records most people would only
use.. and stateful address and such specified in a separate draft?

Just a thought...
