Quoting the FBI:

85.255.112.0 through 85.255.127.255
67.210.0.0 through 67.210.15.255
93.188.160.0 through 93.188.167.255
77.67.83.0 through 77.67.83.255
213.109.64.0 through 213.109.79.255
64.28.176.0 through 64.28.191.255

Solve said problem easily by destination NATing those IPs on 53/UDP/TCP 
to your own recursive servers, or dump them on Google at 8.8.8.8 if 
you're so inclined.  Extra bonus result: NAT logs will show who needs a 
pleasant email from customer service.

Or you could just let 'em[1] suffer, BoFH-style.

[1] "'em" in this case is "your customer service reps" who will see a 
'higher than normal call volume' should the FBI's warning mean anything.
