Mass ipv6 lookups



HI,

I've compiled my kernels (40+ systems) without IPv6 support and I have no
desire for IPv6 in any format at this time.  However, I see that I am
transmitting IPv6 DNS queries, in IPv4 packets.  Two things:

1.  This is causing my DNS servers to get hammered, almost forcing a DoS.

2.  How the heck do I stop this from happening?  It seems all recent
packages have IPv6 support, so does that mean I'm SOL?

I can't just list all the machines that connect to the server in
/etc/hosts with the ::FFFF:<IP> because there are thousands of machines.

Any help to resolve this is highly appreciated.
