58,627 attributed to registrars in Apr 2026, against 73,218 in 26 Aug 2026’s zone — the zone is 14,591 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 April 2026, which ICANN publishes about three months in arrears; zone files contain no registrar information, so no fresher source exists.
