Thanks for your reply Bert,

I am trying the iptables rules for stopping "questions"
-m string --hex-string "|0000ff0001|"  and not allowing
to overload my small DNSs.

Can you tcpdump? They could simply be sking the question, doesn't mean they
have to *respect* your TC=1 answer. Since that is all we can do, set TC=1.
It does not stop the questions!

We do provide a really small answer that way, which stops the amplification
from working.
