	DNS is a worldwide, global, database.  link-local addresses (and site-
	local addresses) are local to your link (or site).  you cannot reverse-
	resolve (or forward-resolve) link-locals or site-locals.

	if you really want to do that, you have a couple of ways:
	- configure a local nameserver that serves 0.8.e.f.ip6.int, just like
	  you would configure nameservers for private addressees.  be sure not
	  to leak information from the zone.
	- use icmp6 name lookup protocol instead
	  (draft-ietf-ipngwg-icmp-name-lookups-08.txt)

	in any case, link-locals are not really for daily use.
