# faq
- ? How many .js.cn domains are registered?
- There are 339 active .js.cn domains as of September 5, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .js.cn growing or shrinking?
- .js.cn has grown by 97.09% over the last year (+167 domains).
- ? Where does the .js.cn 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 .js.cn 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.
