Registrar figures are for May 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.

Registry operator: Shortdot SA
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

595,408 attributed to registrars in May 2026, against 564,116 in 17 Sep 2026’s zone — the zone is 31,292 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.

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