What is WHOIS?
WHOIS is a query and response protocol used to look up domain registration information. It provides details about who registered a domain, when it was registered, when it expires, and which registrar manages it. This data is stored in databases maintained by domain registries.
Domain Status Codes
Frequently Asked Questions
Why is WHOIS information hidden?
Many domain owners use WHOIS privacy protection (also called domain privacy) to hide their personal information. This is a legitimate service offered by registrars to protect against spam and identity theft.
How can I check if a domain is available?
If our WHOIS lookup shows "Not Registered" or returns no registrar information, the domain may be available for registration. However, always verify availability directly with a registrar before purchasing.
What happens when a domain expires?
Expired domains enter a grace period (typically 30-45 days) where the owner can renew. After that, they enter a redemption period with higher renewal fees, then finally become available for public registration again.
Why do I need to check domain expiration dates?
Monitoring expiration dates helps prevent accidental domain loss. Expired domains can be registered by others, potentially harming your business or brand identity.
