Except there's other ways of doing this. For example Firefox does the same thing and doesn't do this. https://blog.apnic.net/2020/08/21/chromiums-impact-on-root-dns-traffic/ https://blog.apnic.net/2020/08/21/chromiums-impact-on-root-d... > The root server system is, out of necessity, designed to handle very large amounts of traffic. As we have shown here, under normal operating conditions, half of the traffic originates with a single library function, on a single browser platform, whose sole purpose is to detect DNS interception. Such interception is certainly the exception rather than the norm. In almost any other scenario, this traffic would be indistinguishable from a distributed denial of service (DDoS) attack. > Could Chromium achieve its goal while only sending one or two queries instead of three? Are other approaches feasible? For example, Firefox’s captive portal test uses delegated namespace probe queries, directing them away from the root servers towards the browser’s infrastructure.
