I really do not get the lack of DHCPv6, the Apple 'it should be easy' is all very well and good, but it really does not help those people who have to run the networks at all. 

So for the foreseeable future SLAAC seems to be a requirement especially for WiFi operators for example who will have to support a multitude of unknown hosts. Has anybody found a usable method of achieving IPv6 address logs for such networks or will I just have to write some awful sniffer that spits out into a database that later on I'll have to correlate with WiFi AP RADIUS logs?
