Change your resolver.  The name*server* can nothing do about what the 
*client* asks of them.  The fact that you connect to a nameserver via 
IPv4 says nothing about what kind of queries you want to send to it.  At 
the moment you can't change the behavior of the resolver in libc and (as 
far as I know) that of the isc implementation either.  There has been a 
discussion to provide a environment variable to emit only IPv4 queries, 
though.
