# faq
- ? How many .sd.us domains are registered?
- There are 6 active .sd.us domains as of September 5, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .sd.us growing or shrinking?
- .sd.us has shrunk by 14.29% over the last year (-1 domains).
- ? Where does the .sd.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 .sd.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.
