Registrar figures are for April 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.

Registry details

From the IANA Root Zone Database and RDAP bootstrap.

Technical backend: CentralNic (Team Internet) via rdap host
Delegated: 2 May 2015
Nameservers: a.nic.icu, b.nic.icu, c.nic.icu, d.nic.icu
RDAP: https://rdap.centralnic.com/icu
Zone data: CZDS access approved — counted daily

598,559 attributed to registrars in Apr 2026, against 564,344 in 19 Aug 2026’s zone — the zone is 34,215 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, May 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 19 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.
