Domains by month, Aug 2015 – 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 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.
