Domain registry operators
A registry operator runs a top-level domain: it holds the authoritative list of every registration under that extension and sets the wholesale price registrars pay. It is not the company you buy from — that is the registrar — and the two are frequently confused. 12 operators run the 229 extensions we track, and this page names each one exactly as IANA's root database does.
Each operator page also answers a question no registry publishes about itself: what its whole portfolio costs to keep. The renewal figures are computed from the prices we verify at the registrars that sell each extension, so they describe what a buyer actually pays rather than the wholesale rate the registry charges.
