# faq
- ? How many .com.bt domains are registered?
- There are 54 active .com.bt domains as of September 5, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .com.bt growing or shrinking?
- .com.bt has grown by 12.50% over the last year (+6 domains).
- ? Where does the .com.bt 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 .com.bt 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.
