Tightened DNS security question re: DNS amplification attacks. [SEC=UNCLASSIFIED]

I still see a few new ones each day, here is my current bind acl for
blocking them:

acl blacknet {
69.50.142.11/32;
66.230.160.1/32;
66.230.128.15/32;
76.9.16.171/32;
63.217.28.226/32;
206.71.158.30/32;
64.57.246.146/32;
67.192.144.0/32;
};

These have all been seen in the last few days, verified by hand.
