If your DNS server isn't replying to requests, your DNS server is broken. That has nothing to do with v6.

  If the problem gets fixed by simply disabling v6, it has much to do with v6.

    It might get hidden by disabling v6, but not fixed. And if your DNS server fails to reply to an AAAA lookup over v4, that's 100% not a v6 problem.
