About .cern
.cern is a brand top-level domain owned and operated by CERN, the European Organization for Nuclear Research, located on the Franco-Swiss border near Geneva. CERN is one of the world's largest and most respected scientific research institutions, best known for operating the Large Hadron Collider and for being the birthplace of the World Wide Web. The organization conducts fundamental research in particle physics and maintains extensive international scientific collaborations.
As a brand TLD, .cern is not available for public registration and is used exclusively by CERN and its affiliated projects. The TLD was delegated through ICANN's new gTLD program, allowing CERN to maintain an authenticated and institutional namespace online. It reflects the organization's long-standing role at the forefront of internet history and its ongoing commitment to transparent, open-access scientific communication on the web.

The .cern dataset
Everything we have on 95 active .cern domains in one downloadable file — fresh export every day.
Buy a dataset to download .cern
The full .cern slice (672 B JSONL, fresh daily exports) lives inside each dataset. Get one from €29 to €599 per month and download immediately.
How to download the .cern domain list
The complete .cern domain list is available as one structured file. Every entry in the list is a single registered domain exported with its full record, so you can work it all offline instead of crawling it yourself.
Pick the dataset that fits your use case, then download the .cern list in JSONL (zstd-compressed) — the very same list that powers our API. A free sample of the list is available before you pay, and you can re-download the latest export any time during your access month.
Each .cern list includes, for every domain:
- DNS, RDAP and WHOIS records — registrar and dates across the full list.
- Detected technologies for each site in the list.
- Hosting IP, country and PageRank / Harmonic ranking.
- A daily-refreshed export, so the list you receive is never stale.
Frequently asked questions
How many .cern domains are there?
webatla tracks 95 active .cern domains, re-exported every day — each with its DNS, RDAP/WHOIS, detected technologies, IP, hosting country and ranking.
Can I download the full list of .cern domains?
Yes, the full .cern list downloads as structured JSONL (zstd). A free sample is available first.
What's included for each domain, and how fresh is it?
Every domain carries the full schema — DNS, RDAP/WHOIS, technologies, IP & country, PageRank and Harmonic — re-exported daily.
How do I download the .cern domain list?
Choose a dataset, and the full .cern list is then yours as a single JSONL file in your account. You can re-download the list anytime during your access month, and a free sample is available to download first.
What format is the .cern list in?
The list is yours to download as JSONL compressed with zstd, one domain per line, ready to load straight into any database or script. The exact same list is also reachable through our API.
Can I download just the .cern domains, or the whole database?
Both. Each dataset is a single downloadable file, buy just the one you need for .cern. Or buy All data for the entire database: every dataset combined (identity, ranking, technologies, DNS and RDAP/WHOIS) in one file. Daily fresh export.
