# faq
- ? How many .so domains are registered?
- There are 19,920 active .so domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .so growing or shrinking?
- .so has grown by 47.35% over the last year (+6,401 domains).
- ? Where does the .so 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 .so 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.
