Registrar figures are for February 2026. ICANN publishes monthly registry reports about three months in arrears, and they are the only source that attributes domains to registrars — zone files do not contain registrar information. Methodology.

Data currency. Domain counts on this page are from zone files dated 19 September 2026 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. Full detail on methodology and live pipeline status.
