# faq
? How many .xxx domains are registered?
There are 37,035 active .xxx domains as of August 31, 2026, according to DNSniffer's daily count of zone-file and certificate-transparency records.
? Is .xxx growing or shrinking?
.xxx has grown by 12.83% over the last year (+4,211 domains).
? Where does the .xxx 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 .xxx 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.
