# faq
- ? How many .mtr domains are registered?
- There are 7 active .mtr domains as of October 12, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .mtr growing or shrinking?
- We do not yet hold a full year of history for .mtr. The chart above shows everything we have recorded so far.
- ? Where does the .mtr 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 .mtr 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.
