The Secrets Behind Domain Names
summary
A technical walkthrough of how DNS resolves devox.fr from ARPANET roots through the 13 root-server letters, then delegation to the .fr registry, including actual resolution path and timing measurements. Provides concrete numbers (about 1,480 TLDs: 1,228 gTLDs and 252 ccTLDs), typical TTL (~24 hours), and a 45-day redemption window; explains cache-poisoning attacks and DNSSEC mitigation, operational details like EPP (XML over TCP), and modern privacy options such as DNS over HTTPS on port 443 with their trade-offs, plus pricing and renewal pitfalls illustrated with examples.
