Bulk Domain Availability Checker

Twenty-five per run. That is the point where registries start rate-limiting a single caller, and a slower tool that gets throttled is worse than a fast one that respects the limit. Run it again for the next batch.

It uses RDAP, the protocol ICANN mandated to replace WHOIS. RDAP returns structured JSON instead of scraped text, so registrar and expiry come back reliably rather than parsed out of free-form output.

For every TLD that publishes an RDAP service - all gTLDs and most ccTLDs. A few registries, .de among them, still do not. Those come back marked unconfirmed rather than guessed at, because a false 'available' is the one answer this tool must never give.

No. RDAP queries go to the registry, not to a registrar's search box, and nothing you type is logged against your session or sold on. Front-running has historically come from registrar search tools, not registry lookups.

Usually a premium or reserved name: unregistered at the registry, but withheld from general sale. RDAP reports the registration status, which is the truth about who holds it, not the sales status.

It is when the current registration lapses, not when the name becomes buyable. Expect a 30-day grace period plus a 30-day redemption window after that, and most owners renew. Treat it as a signal, not a date to plan around.

No - example.com and example.io are different registrations at different registries. List every extension you actually want, one per line.

Four bulk runs a minute from one IP. Results are cached for an hour, so re-checking the same list costs nothing.
