# faq
- ? How many .support domains are registered?
- There are 43,758 active .support domains as of October 15, 2026, according to DNSniffer’s daily count of zone-file and certificate-transparency records.
- ? Is .support growing or shrinking?
- .support has grown by 35.99% over the last year (+11,581 domains).
- ? Where does the .support 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 .support 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.
