It was also interesting to open the Mac network control pannel, enable my Airport (WLAN) interface, and see the IPv6 global address appear almost instantaneously and in many case having to wait many seconds to minutes for DHCP provided IPv4 address to appear.
Any chance this was merely due to a difference in scaling, with IPv4 DHCP usage being large-scale and IPv6 being small?
I suppose the more constructive way to ask this is: Does anyone know why one worked better than the other?
I don't think there was any IPv6 DHCP, and if there was, most hosts wouldn't have used it because they don't implement it. The advantage of stateless autoconf over DHCP is that with stateless autoconf, a singe router advertisement multicast to all IPv6 hosts can provide an unlimited number of hosts with address information (the hosts still need to do duplicate address detection, but since no reply means success it's hard to fail here) so it's eminently more scalable than DHCP.
