Bulk domain checker FAQ
How many domains can I check at once?
Up to 25 unique domains per run. Paste one per line, or separate with commas or spaces. Checks run in small batches so we stay polite to public RDAP servers.
Is this a drop-catch or backorder tool?
No. This is a bulk RDAP/DNS snapshot: registered, available, redemption, or pending delete. Vacato monitors and alerts — it does not catch or register names for you.
What does Watch all taken mean?
Taken, redemption, and pending-delete names can go on a Vacato watchlist. Enter email for a 6-digit login code (no password) — we add up to 10 names on Free after you verify. Extra names need Pro (100).
Are bulk results a guarantee I can register a name?
No. RDAP shows current registration status, not real-time registry cart availability. Use continuous monitoring for taken names you care about.
Can I share a bulk shortlist URL?
Yes. After a run (or by pasting into the box), the address bar updates to ?q=domain1,domain2,… so you can copy the link for a co-founder. Cap still applies.
