aaaa

I pay for a DNS service based on queries per second.

We are not using IPv6, but a large number of queries (that I pay for) are coming in for AAAA records. I understand that most DNS stacks will now ask for A and AAAAs at the same time, and that I can't change that.

What I /would/ like to do is put something in the AAAA records with a long TTL. (decreasing my hit rate)

Is there anything I can put? Null? The equivalent IPv4 Address?

Any guidance would be appreciated.
