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.

Share of .联通 by registrar
Reserved for non-billable transactions where Registry Operator acts as Registrar	2	66.67%
Internet Domain Name System Beijing Engineering Research Center LLC (ZDNS)	1	33.33%

3 attributed to registrars in Apr 2026, against 3 in 19 Aug 2026’s zone — the zone is 0 larger. 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 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. Full detail on methodology and live pipeline status.
