🌐 Domain WHOIS Lookup

📖 About Domain WHOIS Lookup

WHOIS is a protocol used to query databases that store information about registered internet resources, particularly domain names. Our tool provides easy access to this public information.

✨ Features

• Comprehensive Data: Registrar, creation date, expiration date, nameservers, and more
• All TLDs Supported: Works with .com, .net, .org, .io, country codes, and new gTLDs
• Domain Status: Check if a domain is registered or available
• RDAP Support: Uses modern RDAP protocol when available
• Raw WHOIS Data: View complete WHOIS response
• Fast Lookup: Instant results from WHOIS servers
• No Registration: Free to use, no account needed

🎯 How to Use

1. Enter a domain name in the search box (with or without www)
2. Click "Lookup" or press Enter
3. View comprehensive domain information
4. Optionally, view raw WHOIS data for technical details

📊 Information Retrieved

• Domain Name: The queried domain
• Status: Registered or Available
• Registrar: Company managing the domain registration
• Registration Date: When the domain was first registered
• Expiration Date: When the registration expires
• Updated Date: Last modification date
• Nameservers: DNS servers for the domain
• Domain Age: How long the domain has been registered
• Registrant: Domain owner (if public)

💡 Common Use Cases

• Domain Research: Check if a domain is available before purchasing
• Expiration Tracking: Monitor when domains expire
• Registrar Information: Find out who manages a domain
• Contact Details: Find domain owner contact information (when public)
• Nameserver Check: Verify DNS configuration
• Due Diligence: Research domain history before buying
• Competition Analysis: Check competitor domain details
• Security: Verify domain ownership and authenticity

🔒 Privacy & GDPR

Many domain registrants now use privacy protection services due to GDPR and privacy laws. This means personal information like names, addresses, and phone numbers may be hidden or redacted in WHOIS results.

• Privacy protection is increasingly common
• Registrar contact information is usually still visible
• Technical details (nameservers, dates) remain public
• Some TLDs have stricter privacy rules than others

🌐 WHOIS vs RDAP

• WHOIS: Traditional protocol (port 43), text-based responses
• RDAP: Modern RESTful HTTP protocol with structured JSON data
• Our tool automatically uses RDAP when available, falls back to WHOIS
• RDAP provides more consistent, machine-readable data

⚠️ Limitations

• WHOIS data accuracy depends on the registrar
• Privacy protection may hide owner details
• Rate limits may apply for frequent lookups
• Some TLDs have restricted WHOIS access
• Information is retrieved from third-party WHOIS servers

📝 Tips for Better Results

• Enter domain without http:// or www (e.g., "example.com")
• Include the TLD (.com, .net, .org, etc.)
• Check spelling carefully
• Try alternative TLDs if domain seems available (.net, .org, .io)
• Some country TLDs may have special requirements
