About the Whois Lookup Tool

This free tool helps you look up domain registration information using the WHOIS protocol. WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name.

What is WHOIS?

WHOIS is a protocol that provides information about domain names, IP addresses, and autonomous system numbers. It was originally created to help system administrators find and fix system problems. Today, it's commonly used to look up domain ownership and registration details.

Common WHOIS Information:

• Domain Status: Shows if the domain is active, pending, or expired
• Registrar: The company that registered the domain
• Creation Date: When the domain was first registered
• Expiration Date: When the domain registration expires
• Name Servers: The DNS servers that handle the domain
• Registrant Contact: Information about the domain owner (may be hidden for privacy)

Privacy Considerations:

Many domain registrars now offer WHOIS privacy protection services that hide the registrant's personal information from public WHOIS queries. This helps protect domain owners from spam and identity theft.

Using WHOIS Data:

• Domain Research: Investigate domain ownership and history
• Legal Purposes: Identify domain owners for legal matters
• Technical Support: Troubleshoot domain-related issues
• Security: Investigate potential phishing or malicious domains
