# faq
- ? How many .ma.us domains are registered?
- There are 61 active .ma.us domains as of September 4, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .ma.us growing or shrinking?
- .ma.us has shrunk by 1.61% over the last year (-1 domains).
- ? Where does the .ma.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 .ma.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.
