Frequently Asked Questions

See our FAQ for more answers.

Can I download sample datasets for the .icu zone?

Yes. Download a sample .icu domain list or a sample .icu dataset.

What is a basic domain list, and how does it differ from a detailed dataset?

Both cover the same 1,029,405 registered domain names in the .icu 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 .icu 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 .icu domains?

Yes. The New domains list contains only the .icu 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=icu&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 .icu 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 .icu basic list is about 5.4 MB and the detailed dataset about 10.0 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 .icu domain was first introduced in May 2018 and has gained quick popularity over the years. It is managed and supervised by ShortDot SA, an internet registry based in Luxembourg. The word icu stands for ‘’I see You,’’ and it is generally used by individuals and businesses delivering great customer service.

Companies and organizations use this domain name extension as it is versatile, short, and secure. It also provides additional privacy protection and is not restricted to an area or region. This makes it available to anyone across the globe. With the .icu domain, you can highlight your online presence and target a global audience, as the domain name is universal and has no location specificity.

Although it is new in the list of generic top-level domains, the .icu domain is making a huge success in the digital world.
