Heavy DNS port 53 traffic from client

New Contributor III
We have client device, a Amazon Fire TV, that streams from PlayStation Vue,  when I view the traffic usage for that client in ZD after constant streaming, it shows that 85% of the traffic is going over port 53 DNS, and only the rest is HTTPS.  It is not a small amount of data either...1.7GB down in one hour over port 53.  Any theories why so much traffic is on port 53...I would have expected almost all of the traffic would be on https.

You would need to take a sniffer trace to identify the source/destination and how much DNS is utilizing your bandwidth.
