# faq
- ? How many .mu domains are registered?
- There are 7,138 active .mu domains as of October 13, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .mu growing or shrinking?
- .mu has grown by 33.30% over the last year (+1,783 domains).
- ? Where does the .mu 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 .mu 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.
