Frequently Asked Questions
See our FAQ for more answers.
Can I download sample datasets for the .bio zone?
Yes. Download a sample .bio domain list or a sample .bio dataset.
What is a basic domain list, and how does it differ from a detailed dataset?
Both cover the same 91,575 registered domain names in the .bio 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 .bio 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 .bio domains?
Yes. The New domains list contains only the .bio 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=bio&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 .bio 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 .bio basic list is about 408 KB and the detailed dataset about 1.2 MB.
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.

The .bio domain actually has a limited client base. In 2021, roughly 12,000 domains were registered with the .bio top-level domain. This domain extension is perfect for industry experts of life sciences and biotechnology, offering them a prominent identity to demonstrate their research or achievements.
The fact that .bio is not saturated till now provides a considerably open choice for domain name selection. The domain is recognizable all over the world and not restricted to biology-related use; meaning it can be registered by anyone, anywhere, without any restriction.
