Thanks for bring light around this. If I understand correctly when admin 
declare zone for reverse IPv6 loopback like me (and all empty zones) it 
simply doesn't work. When I declared zone like you all works as 
expected. But I'm not sure what you're going to fix to 9.4.2. Will it be 
that "my" declaration will work fine?
