What Is a WhoIs Lookup?

A WhoIs Lookup Tool helps you see who owns a domain, when it was registered, when it expires, and where it’s hosted. It’s widely used by website owners, SEOs, and IT professionals to verify domain details.

SEO Site Checker’s WhoIs Lookup Tool is unique because it combines two tabs in one tool:

  • WhoIs Tab → Domain ownership, registrar info, registration & expiry dates.
  • DNS Records Tab → A, MX, TXT, and NS records that show how the domain is configured.

This dual setup means you can check both ownership and technical records in a single lookup.

 

About WhoIs Privacy & Cloudflare Proxies

Some domains hide ownership details using WhoIs privacy services or proxy providers like Cloudflare. This protects personal data but means the displayed information may show the registrar or proxy service instead of the actual owner.

  • WhoIs Privacy → Replaces real contact details with proxy information.
  • Cloudflare Proxies → Mask server IP addresses for security, so DNS/IP results may differ.

👉 If a domain uses privacy protection, you may not see the actual owner, but you’ll still see useful DNS and registrar details.
