my whois

● Bulk lookup

A hundred domains, one paste.

Paste up to 100 domains — one per line, comma-separated, or whitespace-separated. We’ll return registrar, age, expiry, health score, SSL status, and DNSSEC for each in one go. Export the result as CSV.

One per line, comma-, or space-separated. Up to 100 per run.

When this is useful

  • SEO audits. Compare 50 candidate domains by age and registrar in one paste, instead of running 50 individual lookups.
  • M&A due diligence. Pull a CSV of every domain an acquisition target owns, with current expiry status and SSL health.
  • Brand monitoring. Drop in a list of typo-squat variants of your brand and see which ones are registered, by whom, and when they expire.
  • Portfolio management. If you own a domain portfolio, paste them all in to see at a glance which renewals are overdue.

Limits and fairness

Each request is capped at 100 domains and 6 requests per hour per device. Runs are rate-limited so we don’t hammer the registries — we lean on the same RDAP cache the rest of the site uses, so subsequent runs of the same domain are essentially free. No accounts, no API keys, no email required.
