# faq
- ? How many .tennis domains are registered?
- There are 2,130 active .tennis domains as of August 31, 2026, according to DNSniffer's daily count of zone-file and certificate-transparency records.
- ? Is .tennis growing or shrinking?
- .tennis has grown by 24.13% over the last year (+414 domains).
- ? Where does the .tennis 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 .tennis 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.
