When I open the flood gates, over a 5-min sample from a single host I received well over 61,000 queries. The size of the records being requested cause this to be an (unintended) amplification attack, as a 30Mbps inbound sum is getting amplified to 150-200Mbps outbound.

Hi all, Is anyone seeing excessive DNS traffic from game consoles (Xbox One,PS4)running Netflix? Starting 9/29 we have been seeing significant volume of DNS traffic from game consoles on our campus to our caching recursive boxes. Logs show repeated requests for api-global.netflix.com and nrdp.nccp.netflix.com. Anyone else experiencing this? Eamon
