Bulk WHOIS lookup
Look up public RDAP records for up to 10 domains per run.
How it works & common questions
How many targets can I check?
Enter one target per line, up to 10 distinct targets. Requests run sequentially. Each item reports its result or failure; stop a run or download results as JSON.
What are the limitations?
Only public targets are supported. Site and upstream limits apply. Missing RDAP does not imply availability; IP registration is not physical location; HTTP duration is not a full page-load metric.
