As of September 12, 2026, the .cern domain list contains 100 active .cern domains, <0.001% of all domains tracked by NetAPI, which makes .cern the #882 largest of 1,584 zones. Net of expired and deleted domains, the zone changed by +3 (+3.09%) in 30 days and by +8 (+8.70%) year over year.
The .cern domain list and the detailed dataset above are refreshed daily, so these figures move with the zone. 8 .cern domains are in the free NetAPI Top 1M. See the Top 1M list.
Frequently Asked Questions
See our FAQ for more answers.
Yes. Download a sample .cern domain list or a sample .cern dataset.
Both cover the same 100 registered domain names in the .cern zone. A basic list is one domain name per line in a gzip CSV. A detailed dataset adds DNS servers, server IP, hostname, emails, phone numbers, and more. See the dataset format details.
Datasets for .cern are updated daily. Active domains are all currently registered names in the zone. New domains are names added in the last 24 hours.
Yes. The New domains list contains only the .cern domains registered in the last 24 hours and is rebuilt every day.
To download it manually, sign in and click the number in the New domains column of the
download table on this page (the Download button next to it gets the full list of active domains).
Through the API, call
/api2/?method=download&zone_tld=cern&dataset_type=list&filter_type=new&token=YOUR_API_TOKEN
(dataset_type=dataset for the detailed dataset); see the API documentation.
Every .cern domain list and dataset is a CSV file compressed with gzip (.csv.gz):
the basic list has one domain name per line, the detailed dataset has one row per domain with the columns described in the
dataset format details.
Compressed, the current .cern basic list is about 1 KB and the detailed dataset about 1 KB.
Any archiver opens gzip files, for example the free
7-Zip on Windows,
and the API can also serve the files uncompressed (format=plain).
Schedule automatic downloads through the API. See the API documentation for authentication and endpoints.
No. We collect contact details from public websites when available. Many domains have no published email or phone, and we do not guarantee these fields on every row. Do not use the data for unsolicited bulk outreach.
