- There are 24,709 active .training domains as of October 16, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .training growing or shrinking?
- .training has grown by 27.69% over the last year (+5,358 domains).
- ? Where does the .training 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 .training 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.
