How many .su domains are registered?
As of October 25, 2026, the .su domain list contains 111,240 active .su domains, 0.032% of all domains tracked by NetAPI, which makes .su the #126 largest of 1,584 zones. 128 new .su domains were registered in the last 24 hours and 2,613 over the last 30 days. Net of expired and deleted domains, the zone changed by +392 (+0.354%) in 30 days and by +1,435 (+1.31%) year over year.
The .su domain list and the detailed dataset above are refreshed daily, so these figures move with the zone. 362 .su domains are in the free NetAPI Top 1M. See the Top 1M list. 128 .su domains are currently listed in the compromised domains feed (0.115% of the zone). See the TLD abuse report.
Frequently Asked Questions
See our FAQ for more answers.
Can I download sample datasets for the .su zone?
Yes. Download a sample .su domain list or a sample .su dataset.
What is a basic domain list, and how does it differ from a detailed dataset?
Both cover the same 111,240 registered domain names in the .su zone. A basic list is one domain name per line in a gzip CSV. A detailed dataset adds the nameservers, the server IP and its country, the hostname, emails and phone numbers found on the website, and, where the registry publishes them, the registration and expiration dates and the registrar. The full list of columns is in the dataset format details.
What are active and new domains?
Datasets for .su 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 .su domains?
Yes. The New domains list contains only the .su domains registered in the last 24 hours and is rebuilt every day. To download it by hand, sign in and click the number in the New domains column of the download table on this page; the Download button next to it fetches the full list of active domains. Through the API, use the download method with the new filter, as described in the API documentation.
Can I download deleted .su domains?
Yes. The Deleted domains list contains the .su domains that were in the zone the day before and have dropped out of it, 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 .su 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 .su 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 additional data listed in the
dataset format details.
The current .su files are about 443 KB (basic list)
and 1.7 MB (detailed dataset) compressed.
Any archiver opens gzip files; on Windows, for example, the free
7-Zip.
Through the API you can also download 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 .SU Zone / Registry Information
After the dissolution of the Soviet Union on December 26, 1991, the domain was expected to be retired, but it was never withdrawn: registrations stayed open because of demand from users and support from the Russian side, and the extension is still in use.
.su is used by businesses and individuals in Russia and other post-Soviet states, often as an alternative when a .ru name is taken. Names are registered directly at the second level, and registration is open to anyone.
Chart Y-axis is scaled to the data range to show day-to-day changes (not from zero).
Based on this dataset and daily threat-intelligence signals. Domains may be listed after observed phishing, malware, spam, botnet, or similar activity; inclusion does not imply malicious intent by the owner, registrar, registry, or host. Updated daily; figures may change as new data arrives.
