Good point. The allegation is "data mining," but I was imagining some kind of back room real-time monitoring situation.The client should cache the DNS. So if I go to Rivals, my phone should know the path. So I am not sure what could be learned. I do not recall length of cache, but I am not sure what could be learned
By the way, there is a sporting event of some kind on.
Still, it wouldn't be that hard for someone with access to the DNS server to simply set up his own hands-free logging operation if he wanted, right?
