Atlas — every domain that ever existed
A database of 706 million domains and 2.17 billion hostnames, built entirely from free public sources. The command center of my domain research.
What it is
Atlas answers a seemingly impossible question: which domains exist at all? There is no official list — registries guard their zones, and nobody sees everything. But if you gather enough free public sources and merge them carefully, you get something surprisingly close to the full picture: 706 million registrable domains and 2.17 billion hostnames.
Where the data comes from
Sixteen sources, none of them paid: the zone files of 965 gTLDs via ICANN’s CZDS program, 304 ccTLDs via the academic OpenINTEL project, the live Certificate Transparency stream (every new HTTPS certificate announces its domain — about 1.6 million a day), the Common Crawl web graph, public lists and rankings. Each source sees a different angle; the power is in the union.
The technical part
Everything lives in PostgreSQL on an ARM machine with 24 GB of RAM — from Oracle’s free tier, naturally. The dashboard shows freshness and coverage per source, a TLD breakdown and domain lifecycle: registered, expired, re-registered.
Why it exists
Because all my domain projects — the auction tracker, the marketplaces, the research — stand on the same fundamental question: “what’s out there?”. Atlas is the answer I built for myself.
