# faq
- ? How many .ut.us domains are registered?
- There are 11 active .ut.us domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .ut.us growing or shrinking?
- .ut.us has shrunk by 8.33% over the last year (-1 domains).
- ? Where does the .ut.us 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 .ut.us 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.
