Dig for link-local

Transport has nothing to do with content in DNS. If your client asks for
an AAAA record it will get the appropriate answer according to the
zone's records (a value or an error condition) regardless on whether the
query was made over IPv6 or IPv4.

That said, you can 'hack' around this expected behavior (see 'no AAAA on
ipv4') in order to help hosts with broken IPv6 connectivity, but you
have to enable it.
