What determines DNS will query IPV6 address?

When I do simple nslookup it does not generate any query for IPV6 (AAAA). But sometimes I see DNS query for both A and AAAA are generated. What decides this? The reason I do not want AAAA query is in most of the cases AAAA records are absent. Hence, if one DNS server fails, the clients keeps attempting to send AAAA query.
