Google dns weirdness

Recommended Posts

I was implementing some suggestions from Fraser tonight, and in the midst of everything I ran into a new (not netduma related) issue. The ps4 reported that I didn't have a DNS connection. I noticed I had left the custom setting for google dns in my wired internet setting. I do this every time there is a large update to download on ps4 (and yes, I know DNS doesn't affect speed - however I've used this trick more times then I care to count and for large downloads, for whatever unknown reason (maybe just path routing?), it has a massive & measureable effect) Anyway, I blew that out and it connected just fine with my isp's dns.

 

However, being the curious type I ran the internet diagnostic on the netduma as I know they ping the google dns server. Last night everything was fine  - tonight's results are below along with ping plotter results. This is the first of many test I've run over the past week since I received the netduma in which I've seen packet loss, let alone the weird google dns results.
