# faq
- ? How many .ck.ua domains are registered?
- There are 914 active .ck.ua domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .ck.ua growing or shrinking?
- .ck.ua has grown by 12.01% over the last year (+98 domains).
- ? Where does the .ck.ua domain count come from?
- We ingest ICANN CZDS zone files and Certificate Transparency logs continuously and snapshot the per-TLD count once a day. A .ck.ua domain is counted as active if it appeared in a zone file in the last 2 days, or - where no zone file is published - if a certificate was issued for it in the last 12 months.
