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 298,527 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.
How often are .sk datasets updated?
The .sk zone is a country-code (ccTLD) zone, and its registry zone file is not directly accessible. NetAPI discovers .sk domains through large-scale crawls: newly discovered domains are added to the list daily, and the full dataset is rebuilt every one to two months. See how updates work.
Can I download only newly registered .sk domains?
Not for this zone. Newly discovered .sk domains are merged into the active list daily, but there is no separate new-domains file for .sk. Daily new-domains lists exist for the zones marked as updated daily in the datasets catalog.
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 1.6 MB and the detailed dataset about 4.8 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.
