WHOIS DOMAIN LOOKUP

Query global WHOIS registries to compile domain registration timestamps, registrar nodes, contact identities, and nameserver delegation parameters.

WHOIS Registry Queries

Input domain name only without http/https schema labels.

Ownership Verification

Verify asset ownership before scanning

We require a same-organization work email plus a DNS TXT or HTTP file proof on your target domain.

1. Start2. Email3. Proof4. Scan

Use a company-managed email that matches the target domain or one of its approved subdomains.

What this checks

  • Email-domain match
  • Domain control proof
  • WHOIS / RDAP / DNS context

DNS and CDN changes can take time to propagate. If your proof is newly published, wait a few minutes and run the proof check again instead of starting a brand-new scan.

Lookup Guidance

  • Queries registry networks globally to retrieve registration age, status, and domain expiration updates.
  • Identifies registry lock indicators (ClientTransferProhibited, ClientDeleteProhibited flags).
  • Logs active nameservers delegation mapping configurations.
