USNO is seeing an apparent coordinated denial of service attack on NTP
originating with the following IPs:
188.8.131.52; 184.108.40.206; 220.127.116.11; 18.104.22.168. I
recommend that you block 22.214.171.124/8, 126.96.36.199/8, and 188.8.131.52/8.
There will likely be more to follow. These appear to originate on
APNIC (Asian Pacific).
Currently we are seeing many tens of thousands of packets per second
