Mac OS X 10.7, still no DHCPv6

Oh... did not know about the heavy baggage...

No, when I first played with IPv6 only network, I found out that RD was silly, it gives an IP adddress but no DNS, and you have to rely on IPv4 to do that. silly, so my understanding is then people saw the mistake, and added some DNS resolution... Because the only option was to get DHCPv6 to get the DNS, but then why create RD in the first place?

So I found this whole saga, to put it mildly "stupid", like when people were talking about migrating to IPv6 but the root servers did not even have an IPv6 address: silly!

So I really don't care between RD and DHCPv6, what I care, is that they should be able to do their job correctly on their own.

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.
