# faq
- ? How many .co.it domains are registered?
- There are 1,995 active .co.it domains as of September 3, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .co.it growing or shrinking?
- .co.it has grown by 203.19% over the last year (+1,337 domains).
- ? Where does the .co.it 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 .co.it 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.
