BulkUp to 200 names · registry RDAP · CSV
Domain availability checker
Ask each registry whether it holds a registration for your shortlist of names.
Commas, spaces and URLs are fine. Ctrl+Enter (⌘+Enter) starts the check.
“No registration found” is not a promise that you can register a name. It means the registry's RDAP server answered 404. A name can still be unavailable because it is reserved by the registry, blocked by policy, sold at a premium price, restricted to local residents, or caught in a deletion queue. Only a registrar's checkout gives a final answer.
TLDs without a browser-reachable RDAP service, such as .de at the time of the bundled snapshot, show as Unknown.
How it decides
Each name goes to the RDAP server of its top-level domain, a few at a time. A record coming back means the name is registered; the detail column adds its expiry date and flags names already being deleted. An HTTP 404 means the registry has no registration for it. Anything else, from a missing RDAP service to a timeout or a rate limit, is reported as Unknown with the reason.
The names you check go only to the registries' RDAP servers, never to a registrar and never to DNS Raven.
Questions
Why would a name with no registration still be unavailable?
Registries keep lists of reserved and blocked names that never appear as registrations, and some sell premium names at higher prices. Country-code registries may also require a local presence.
When does a deleted domain become available?
For most generic TLDs, a deleted domain spends about 30 days in its redemption period and then around five days pending delete before it is released.
Can I check names with accents or other scripts?
Yes. Internationalised names are converted to their xn-- form before the lookup, as a registrar would do.
