# faq
- ? How many .foo domains are registered?
- There are 9,800 active .foo domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .foo growing or shrinking?
- .foo has grown by 99.07% over the last year (+4,877 domains).
- ? Where does the .foo 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 .foo 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.
