In use since

2019

RDAP server

Registry model

Thick — contact data in the registry record

HTTPS

Mandatory — the whole extension is HSTS-preloaded

After expiry

Up to 45 days’ renewal grace → 30 days’ redemption → 5 days’ pending delete

Google Registry's extension for developers, open to everyone since 2019. The whole extension is on browsers' HSTS preload list: a .dev site only loads over HTTPS and does not load at all without a valid certificate. That makes the TLS section of the result page especially relevant for .dev names.

Look it up live: web.dev

The result page shows the registry's RDAP record: registrar and IANA id, abuse contact, dates, explained EPP status codes, nameservers and DNSSEC. Since ICANN retired the classic WHOIS requirement at the start of 2025, RDAP is the authoritative source for .dev; an individual registrant's personal details are usually redacted.

Next to the registration data you get live DNS, SPF/DMARC, the TLS certificate, the HTTPS response and the abuse history of the hosting addresses on ip-db.com. Type just a name (e.g. example) and .dev is added; the same data is available from the JSON API.
