Bulk Domain Lookup
Check registration status for up to 20 domains at once — one per line.
Duplicates are removed automatically. Requests are processed with a bounded number running at once — never unlimited simultaneous lookups.
About this tool
Checking domains one at a time doesn't scale for a portfolio review, a client audit, or a brand monitoring list. This tool validates and de-duplicates your list, then looks up every domain with a bounded number of lookups running concurrently — fast, but never sending unlimited simultaneous requests to any registry — and lets you export the full result set as CSV.
Limits
- Up to 20 unique domains per submission.
- A limited number of bulk submissions per minute, to keep the service fast and available for everyone.
- Invalid entries are skipped and listed separately, rather than silently dropped.
