Hi, > 1) What's the pattern with which addresses are generated/assigned? Are > they sequential (fc00::1, fc00::2, etc.)? Random? Something else? > We use our dhcpy6d (http://dhcpy6d.ifw-dresden.de) which allows 4 different address categories: - sequential range like fd00::1, fd00::2 - completely random /64 like with privacy extensions: fd00::3d2a:563f:76f1:d94f - plain MAC address like fd00::2034:d4f1:439a - some arbitrary id number given in client configuration like fd00::1, fd00::3421
See http://dhcpy6d.ifw-dresden.de/documentation/config/addresses for details. This way one can hand out for example 2 addresses to clients, one random privacy-aware global and one range or MAC-based for internal use. The bad news is that only Windows 7+ is capable of handling more than one address given by DHCPv6 out of the box. Linux has to be tweaked not to use Network-Manager and MacOS fails completely - maybe would work with some dhclient or dibbler-client. > 2) What about their stability?

MAC and ID based addresses are of course stable, the range based ones intend to be too and the random ones are regenerated whenever a lease expired.
