Hi, thanks for reading.
You are right, this is not a bind issue. It appears with ntp also.
I spoke about resolv.conf because it masked me the problem: it contains my 3 nameservers
But As I mentioned, when one server tries resolving using itself, if works. That's why I noticed lately the problem when adding a non-nameserver ubuntu.
Of course, I made my best to find any network issues, there a no firewall and all takes place in a HyperV network.
When I switch to ipv4 (resolving, ntp) with the same host, all is fine.
TO help reproduce, I'll add 2 more servers, strictly ipv6, one in Ubuntu 16.04 and one in 15.10 and check.

So, I asked a more general and simple question here : https:/ /answers. launchpad. net/ubuntu/ +question/ 294135

I'll tell later
