Frequently Asked Questions
See our FAQ for more answers.
Can I download sample datasets for the .radio zone?
Yes. Download a sample .radio domain list or a sample .radio dataset.
What is a basic domain list, and how does it differ from a detailed dataset?
Both cover the same 2,958 registered domain names in the .radio 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.
What are active and new domains?
Datasets for .radio are updated daily. Active domains are all currently registered names in the zone. New domains are names added in the last 24 hours.
Can I download only newly registered .radio domains?
Yes. The New domains list contains only the .radio 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=radio&dataset_type=list&filter_type=new&token=YOUR_API_TOKEN
(dataset_type=dataset for the detailed dataset); see the API documentation.
What format and size is the file?
Every .radio 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 .radio basic list is about 13 KB and the detailed dataset about 57 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).
How do I automate daily downloads?
Schedule automatic downloads through the API. See the API documentation for authentication and endpoints.
Are emails and phone numbers available for every domain?
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.
Additional .RADIO Zone / Registry Information
