Whois query tool quickly obtains Whois registration information for domain names or IP addresses. Enter domain name, complete URL, IPv4, or IPv6 address; tool automatically identifies and pulls data from corresponding Whois servers, displaying by different server sections for easy viewing of registrar, expiration time, DNS servers, contact information, and more.
Core Features
- Automatic Recognition: Supports domain names, URLs, and IP addresses, automatically extracts and queries
- Multi-server Query: Retrieves data from multiple Whois servers, completely displaying information
- Real-time Query: Click query button to instantly get latest Whois data
- Quick Copy: Each server's query results can be copied separately
- Automatic IP Query: Automatically queries current public IP when opening page without entering content
How to Use
Enter Target
- Enter any of the following formats in input box:
- Domain:
example.com - Complete URL:
https://example.com/path - IPv4 address:
8.8.8.8 - IPv6 address:
2001:4860:4860::8888
- Domain:
- Click "Query" button to start retrieval
View Results
After query completes, results display by different Whois server sections:
- Each server's return data displays independently
- Click upper right copy button to copy complete results from that server
- Data presented in formatted text for easy reading
Default Query
If opening page directly without entering content, tool automatically queries Whois information for your current public IP address.
Query Content Types
Domain Query
Enter domain name (like example.com) to get following information:
- Registrar: Domain registration service provider
- Creation Date: Domain first registration date
- Expiration Date: Domain renewal deadline
- Updated Date: Domain information last modification time
- Name Servers: DNS server list used by domain
- Status: Domain current status (like active, locked, expired)
- Contact Information: Registrant, admin, technical contact (if privacy protection not enabled)
IP Address Query
Enter IP address to get following information:
- Organization: IP address owner or operator
- Network: Network address segment IP belongs to
- ASN Information: Autonomous System number and name
- Country/Region: Geographic location of IP address
- Contact Information: Network admin or technical contact
- CIDR Address Block: CIDR network segment IP address belongs to
Use Cases
Domain Management
Check domain registration and expiration time for advance renewal to avoid loss. Confirm domain ownership and registrar information. Check if domain status is normal (not locked or frozen). Verify domain information changes before and after domain transfer.
Network Troubleshooting
Query IP address attribution to locate network problem sources. Identify suspicious IP operators and geographic locations. Analyze ASN information of network attack sources. Verify CDN or cloud service IP address ranges.
Security Analysis
Check if domain contact information is abnormal. Verify domain registrar and expiration time to prevent domain hijacking. Query phishing website registration information to assist in tracing. Analyze malicious IP attribution and network segments.
