Two issues: both Google and Cloudflare offer DNS over HTTPS (see: https://dns.google.com), and (to echo others) you haven't cited how you've determined that Google is less DDoS-resistant - aside from their massive DCs, GCE, and self-owned transit cables, Google even runs Project Shield and took over DDoS protection for Brian Krebs after Akamai stopped their … Cloudflare claims that their DNS service will speed up your internet, but let’s put that claim to the test. Support for it is still poor though. This was real. Google’s DNS servers also offer DNS-over-HTTPS, so that feature is also not exclusive to Cloudflare. Cloudflare acts as a proxy – essentially hiding the origin IP address of web server with Cloudflare’s custom generated name servers. The reason consumers don’t see DNS frequently however, is that most of them are already set to either your ISP’s DNS (typical) or an existing public DNS server, like those offered by Google (188.8.131.52). However, just looking at the data we have here, it appears that Google is actually doing better. We’ll be skipping inferential statistics on the overall data set, as I promise you, it is absolutely useless and gives no additional value. While the technical standard is there and set in stone, the effective and widely-believed standard is that the address is unusuable. Finally, while Google has been victim to DDOS attacks in the past, those are few and far in the between. Until Cloudflare DNS offered DNS resolution over TLS feature, Google DNS did not have such a feature. In the frequency distributions, we saw both DNS resolvers performning similarly if looking at the entire spectrum. Displayed below is a frequency distribution of RTT’s for each DNS server, in intervals of 10ms. Estd. Take the results as is. Cloudflare’s DNS offers a few key “advantages” in that it: While most of these benefits sound nice, most of them don’t really impact much anyways. Google DNS is fast. A couple of months ago I did a performance comparison between some of the top free DNS Resolvers available. This typically takes around 20-50ms depending on your DNS server and internet speed. Build The Next Generation of Cybersecurity Training and Academic Study. Previously, 184.108.40.206 was owned by APNIC (and still is, actually). This essentially is compressing Cloudflare’s data set and shows that Google’s may have much less spread in variability. Every cookie or web cache stored can actually track you down to the very MAC address of your Network Interface unit & your computer IP. Cloudflare also supports DNS over HTTPS.
