lots of AAAA query, why?

[MontyRee]

Hello, all.
 
I operated bind dns(9.x) when I see the query log, I can see like below.
First query AAAA and query A  again.
 
named[6252]: client xxx.xxx.xx.xx#50654: query: test.example.com IN AAAA +
named[6252]: client xxx.xxx.xx.xx#50654: query: test.example.com IN A +

As I know, AAAA is an ipv6 related query, but all my systems use ipv4 based.
 
So is there any way to disable  this AAAA query?
 
 
Thanks in advance.
