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. jms [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. -- Joel M Snyder, 1404 East Lind Road, Tucson, AZ, 85719 Senior Partner, Opus One Phone: +1 520 324 0494 jms@Opus1.COM http://www.opus1.com/jms
