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: Identity Digital Limited
Technical backend: Identity Digital via rdap host
Delegated: 2 Jun 2014
Nameservers: a0.nic.bio, a2.nic.bio, b0.nic.bio, c0.nic.bio
RDAP: https://rdap.identitydigital.services/rdap
Zone data: CZDS access approved — counted daily

61,929 attributed to registrars in May 2026, against 71,919 in 19 Sep 2026’s zone — the zone is 9,990 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.

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 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.
