How DOA Domains Bulk Engine Works
1
Quad-DNS Probing
Checks NS, A, AAAA, and SOA records across parallel resolvers (Cloudflare, Google, Quad9, OpenDNS). Active records confirm the domain is taken within ~30ms.
2
Authoritative RDAP Verification
For NXDOMAIN responses, the engine queries authoritative registry endpoints (e.g. Verisign RDAP for .com/.net) to distinguish between parked/unconfigured domains and genuine available names.
