New (And Newly - Changed) Fully Qualified Doman Names: A View of Worldwide Changes to DNS
summary
Farsight builds two real‑time feeds — a newly‑observed FQDN stream (roughly 150–300 new hostnames per second, about one new delegation per second or ~50,000/day) and a DNS changes stream (29 million changes in 24 hours; ~7M new RR names; extrapolated billions of FQDNs/year). Processing sits in RAM as a continuous in‑RAM processing pipeline that filters CDN noise and junk to surface phishing, DGA/fast‑flux activity, CNAME ad‑evasion and other actionable DNS events.
