Re: Mac OS X 10.7, still no DHCPv6

The documents are done, but, I would argue that neither provides a mature
set of features.

Yes, they've (sort of) resolved the DNS server issue for SLAAC, but, that's
recent and getting it into vendor support will be nice. The lack of NTP and
certain other options in SLAAC is still a disappointment and I would
argue that a fully matured SLAAC process would include a mechanism
for specifying extensible choices of things.

For DHCP, the lack of ability to deliver routing policies or recommendations
through DHCP is a roadblock for some deployments which is still in place
in the documents and should be fixed to produce a mature implementation.

Look, can we stop arguing about whether someone needs DHCP or not,
whether they need SLAAC or not. Let's just get both solutions to a mature
and useful state where a network administrator can pick the one that works
best for their environment and move on.

Devices, routers, OSs, etc. should support both. The IETF should stop letting
the two working groups focus on damaging the other protocol and we should
stop treating this as a competition or a battle and start treating it as options
to accomplish a task.

The documents are done at least for sufficient pieces to make it work.
it's in the hands of vendors and has been for a while. The simple fact
is that if you want to do it a particular way and you have an installed
base that doesn't support doing it that way, then you're not doing it
that way.

Yes I don't understand why we need DHCPv6, true RD did not have DNS information to pass, but that is fixed, no?

Mac OS X 10.7 does support RDNSS (RFC 5001) so it is able to get DNS
server information in an IPv6-only environment.  Of course nobody else
has implemented that yet, making Apple a "special case" host once
again (I don't even think Cisco supports the option in their T series
yet).

radvd and rdnssd work together on Linux nicely to provide RDNSS support. 
Works a treat.
