The operator name is the exact TLD Manager string from IANA's root database, which is a registry record rather than a corporate hierarchy. We do not merge strings that may belong to the same company, because merging would assert a relationship the record does not state.

What these extensions cost

FAQ

Who runs .io?+
.io is operated by Internet Computer Bureau Limited. That is the TLD Manager string published in IANA's root database, which is the authoritative record of who runs each top-level domain. The registry operates the extension; the company you buy a domain from is a registrar, and many registrars sell the same extension at different prices.
Can I register a domain directly with Internet Computer Bureau Limited?+
Generally no. Registry operators sell wholesale to ICANN-accredited registrars rather than to the public, and registrars set their own retail prices on top. That is why the same extension costs different amounts at different registrars, and why the cheapest registrar for one extension is often not the cheapest for another.
Do these extensions get more expensive after the first year?+
Often, and this portfolio's steepest example is .io: a first year of $34.98 against a renewal of $75.98, which is 2.2 times as much. The discount is set by the registrar rather than the registry, so it varies between sellers of the same extension. Judge any of these on the renewal column.
