Reminds me when couple years ago I plugged the TV to the internet (so my relatives kids can watch YT) and I forgot to unplug it for almost a week after, only to find the router dns resolved (and blocked) a million queries, all from that one TV!

I love when it keeps checking some random DNS address, because who knows, with a TTL of 64000 it may just have changed in the last seven milliseconds!

The traffic generated here is network scans, not external traffic, and so blocking DNS wouldn’t have helped.
