Bulk Domain Availability Checker

Filters by DNS for speed, then verifies the survivors against the registry via RDAP for an authoritative answer.

Note: RDAP verification is enabled for .com, .net, .org, .io, and .ai. Other TLDs fall back to DNS-only results, which can occasionally mark a registered (but DNS-inactive) domain as available — verify at a registrar before purchasing.

Enter domain names (one per line):

You can but don't need to include ".com", it will automatically add it if missing.
You can but don't need to remove spaces, it will automatically remove spaces.
