IANA-accredited registrars indexed in WhisperGraph · last refreshed · curated set fetched

Whisper Internet Directory documents 50,660 domain registrars — every registrar observed in WHOIS data, identified by its IANA numeric ID. Each registrar has a canonical page at /registrar/iana-<id> listing its domain count, sample registered hostnames, and abuse contact.

How to find a registrar page

Append the IANA registrar ID prefixed with iana- to /registrar/. The page is generated on first visit and cached at the edge for subsequent reads.

Curated set

57 hand-picked registrars listed below, sourced from IANA Registrar IDs (ICANN-Accredited Registrars). This is a curated subset for navigation — not a ranking, and not the directory's extent. Every IANA-accredited registrar has a page; try any ID in the URL bar.
