Nope, different. No EUI64 at all - goes straight to randomized IIDs, but (cough) not to be confused with Temporary/Privacy IIDs. Randomized Link-local, randomized non-link local (Site|UniqueLocal|Global). FWIW - WinXP uses 24hours/change_in_prefix/reboot as the default criteria for new Privacy IID creation, is that not aggressive enough? I'd be curious to know what makes it "awful" IYO, I use it daily and have few complaints ... ? (I think the bigger / better complaint against WinXP is the lack of IPv6-transport support for DNS ... and perhaps the lack of DHCPv6 client functionality as well) /TJ
