13,868 attributed to registrars that month, against 13,653 in 17 Aug 2026’s zone — the zone is 215 smaller. 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.

Domains by month, Apr 2023 – Apr 2026

From ICANN's monthly registry reports — the registry's own count, summed across registrars. This is the long history: it reaches back to delegation, where the daily series below can only start when this site began collecting zone files.

Data currency. Domain counts on this page are from zone files dated 17 August 2026 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.
