Frequently Asked Questions
See our FAQ for more answers.
Can I download sample datasets for the .sk zone?
Yes. Download a sample .sk domain list or a sample .sk dataset.
What is a basic domain list, and how does it differ from a detailed dataset?
Both cover the same 488,710 registered domain names in the .sk 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 .sk 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 .sk domains?
Yes. The New domains list contains only the .sk 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=sk&dataset_type=list&filter_type=new&token=YOUR_API_TOKEN
(dataset_type=dataset for the detailed dataset); see the API documentation.
Can I download deleted .sk domains?
Yes. The Deleted domains list contains the .sk domains that were in the list of active domains the day before and are missing from it today, so it covers the last 24 hours and is rebuilt every day. Deleted domains are available as a list of domain names only, there is no detailed dataset for them.
A deleted domain is not necessarily free to register. The list records names that have dropped out of the .sk zone: the registration expired, or the domain was suspended or undelegated. After the expiration date a domain normally goes through a renewal grace period and a redemption period, typically 30 to 75 days depending on the zone, during which the current holder can still restore it, and only after a short pending-delete period is it released for registration. Some names return to the zone when the holder renews or a suspension is lifted, and then appear in the New domains list again.
What format and size is the file?
Every .sk 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 .sk basic list is about 2.0 MB and the detailed dataset about 9.0 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.
Additional .SK Zone / Registry Information
The .sk domain has made its presence in the European country and has over 465,385 registered domains as of 2023. It mainly targets the Solakia market and assists businesses in building their credibility among local customers. The domain name has multiple sub-domains for commercial or educational websites so everyone can get a unique name for his business.
Being a versatile domain extension, the .sk domain has no registration restrictions. This means the names can be directly registered at the second-level or third level without any prerequisites. It is available to anyone, including Slovakia residents and non-residents. It improves your website’s rankings, especially in the local digital market.
