Daily domain counts
No zone data for this TLD yet
Daily counts require an approved CZDS zone request for this TLD.
The monthly history above is unaffected — it comes from ICANN registry reports.
Registrars
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 activity
Query volumes and EPP operations reported monthly by the registry. The only public signal of how much a TLD is actually resolved rather than merely registered.

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