First, that's an older version, it's generally a good idea to stay
current with nameserver software. If you have any plans to do DNSSEC
validation now, or in the near future, I strongly suggest you evaluate
the latest version of either 9.7.x or 9.6.x. At minimum you should
upgrade to the latest version of 9.5.x.

Second, you didn't mention whether or not you actually HAVE IPv6
transport. Both servers answer fine for me over IPv6 (as I expect they
would) so I'm guessing you don't. If that's accurate, you need to tell
named to stop trying to make requests over it. Since you didn't indicate
what OS you're running, 'man named' is probably your safest bet to find
the answer.
