# faq
- ? How many .ac.tz domains are registered?
- There are 1,250 active .ac.tz domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .ac.tz growing or shrinking?
- .ac.tz has grown by 32.42% over the last year (+306 domains).
- ? Where does the .ac.tz 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 .ac.tz 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.
