# faq
- ? How many .o.se domains are registered?
- There are 12 active .o.se domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .o.se growing or shrinking?
- .o.se has grown by 33.33% over the last year (+3 domains).
- ? Where does the .o.se 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 .o.se 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.
