# faq
- ? How many .bi domains are registered?
- There are 3,119 active .bi domains as of October 14, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .bi growing or shrinking?
- .bi has grown by 94.09% over the last year (+1,512 domains).
- ? Where does the .bi 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 .bi 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.
