Registry operators
The organisations that hold the registry agreement for each legacy gTLD, as recorded in the IANA Root Zone Database. This is the commercial operator — the company that runs the DNS may be different, and is listed under backends.
Showing individual registry operators, as IANA records them.
One company often operates several: combining Radix's two entities would rank them
second by domains, and Identity Digital's three hold 263 TLDs between them.
Combine into parent companies.

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.
