DNS 101: An Introduction to Domain Name Servers
DNS was always a thorn in my side. I never liked the way it was a single point of failure and the first thing attackers looked at when analyzing traffic. Luckily with things like DoH[0], looking at DNS traffic is a lot less invasive in terms of privacy.And even more lucky, and something that serves us all is Mozilla's attempt to bake this as the default (DoH) in their mainline browsers. My only complaint being that they use Cloudflare as the default & Cloudflare acts as a honeypot for Internet traffic. If they (Mozilla) could move away from Cloudflare as a partner then that would be great. (Of course this demands a new privacy-respecting provider to serve requests for the user :p)[0] https://en.wikipedia.org/wiki/DNS_over_HTTPS
