You're not thinking this through. Think of the case where there are 1000 users on a LAN, and one of them desires to use the address privacy option for all the normal reasons. Then think about the policeman / bad guy / secret agent / mafioso with a trace of all traffic from that LAN - he can immediately say that the 999 were using non-privacy-enhanced addresses, and the resulting trace will show him immediately what the 1000th was up to, no matter how many times he changed his address. > > >> If what you want to know is indeed "which site is at the other end", >> wildcards at the /64 level will achieve that with no changes to >> existing code. > > I am not familiar enough with wildcard operation in the DNS. > If it provides for queries that concern only site prefixes, then you > are right: no need for an agreed "wildcard IID". > The result is the same with existing mechanisms, which is clearly better. Read RFC 1034 - or perhaps better, RFC 4592. They've been around for a while (although their behaviour still surprises many).
