11,958 attributed to registrars in May 2026, against 24,334 in 19 Sep 2026’s zone — the zone is 12,376 larger. The two are months apart, and a registry's own count also includes registrations that are not delegated in the zone. Why there are two clocks.

Data currency. Domain counts on this page are from zone files dated and refresh daily. Registrar figures are from ICANN's monthly registry reports for May 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
