I think Masataka meant to say (and said previously) that the DHCP request from the wifi station is, like all packets from the wifi station to the AP, subject to wifi's layer 2 error recovery. It's not unicast but its subject to error recovery anyway.
Mostly correct. But, as I already wrote: 1) broadcast/multicast from a STA attacked to an AP is actually unicast to the AP and reliably received by the AP (and relayed unreliably to other STAs). That is, a broadcast ARP request from the STA to the AP is reliably received by the AP. Because of hidden terminals, L2 broadcast/multicast is transmitted only from AP.
However, at WiFi L2, it is first unicast to AP and then broadcast by the AP.
Your use of nomenclature is incorrect. It'd be like saying my ethernet
Ethernet?
card unicasts a packet to the switch and then the switch broadcasts it out all ports. Or like saying that a packet with an explicit MAC destination
Do you know MAC header of 802.11 contains four, not just source and destination, MAC addresses? Because of hidden terminals and because of impossibility of collision detection, WLAN is a little more complex than your guess.
No offense, but it is not for you or I or Owen Delong to declare that IPv6 is or isn't operational.
A single counter example is enough to deny IPv6 operational.
whether and when IPv6 is sufficiently operational for their use.
The scope is not "their use" but "as a protocol for the entire Internet". Masataka Ohta
