Bulk IP Lookup
Look up detailed information about multiple IP addresses at once. Enter up to 100 IP addresses or upload a CSV/TXT file. Get geolocation, ISP, and more for each IP address.
About Bulk IP Lookup
What does this tool do?
Our Bulk IP Lookup tool processes multiple IP addresses simultaneously (up to 100), providing comprehensive geolocation data, ISP information, and network details for each address. Results include geographic coordinates, timezone data, and can be exported as CSV or JSON files for further analysis.
Why is this useful?
Bulk processing saves significant time when analyzing multiple IP addresses for security investigations, network management, or research purposes. The tool provides structured data output and visualization capabilities that streamline workflows for IT professionals and security analysts.
Who uses this tool?
- Security analysts - Investigate multiple suspicious IP addresses from log files
- Network administrators - Analyze traffic patterns and geographic distribution
- IT forensics specialists - Process incident-related IP addresses efficiently
- Researchers - Study geographic distribution patterns of internet traffic
- System administrators - Monitor and analyze server access patterns
How to perform bulk IP lookup
- Enter IP addresses manually (one per line) or upload a CSV/TXT file
- Supports up to 100 IPv4 or IPv6 addresses per batch
- Complete the reCAPTCHA verification for security
- Click "Lookup IPs" to process the entire batch
- Review results in the interactive table with filtering options
- Export data as CSV or JSON for external analysis
Example
Processing a list of server access IPs reveals geographic patterns, identifies potential bot traffic from specific countries, and helps optimize content delivery strategies based on user locations.
Understanding your results
- Geographic Data
- Country, region, city, and ZIP code information based on IP geolocation databases.
- Network Information
- ISP (Internet Service Provider), organization name, and ASN (Autonomous System Number) details.
- Coordinates
- Latitude and longitude values for mapping and geographic analysis purposes.
- Timezone
- Local timezone information for the IP address location.
- Interactive Map
- Visual representation of all IP locations with clickable markers for detailed information.
Data export formats
- CSV Format: Structured data perfect for spreadsheet analysis and reporting
- JSON Format: Machine-readable format ideal for API integration and automation
- Interactive Table: Sortable and filterable interface for immediate analysis
- Visual Map: Geographic visualization with clustering for pattern recognition
Accuracy considerations
- Geolocation accuracy: Can vary from city-level to country-level precision
- Private IP addresses: Will return errors as they're not routable on the internet
- VPN/Proxy users: May show hosting provider location, not actual user location
- Mobile networks: Location may reflect tower or routing center, not device location
Processing limits and notes
- Maximum of 100 IP addresses per batch to ensure fast processing
- reCAPTCHA verification required to prevent automated abuse
- Private and reserved IP ranges will show error messages
- Results accuracy depends on IP geolocation database quality
Common use cases
Security Investigation
Analyze attack sources by processing IP addresses from security logs, identifying geographic patterns and potential coordinated threats.
Network Traffic Analysis
Understand visitor geographic distribution for content optimization, CDN planning, and regional performance improvements.
Compliance Monitoring
Verify access patterns for regulatory compliance, identifying connections from restricted regions or unexpected locations.
Research and Analytics
Process large datasets of IP addresses for academic research, market analysis, or infrastructure studies.
File upload formats
The tool accepts CSV and TXT files with IP addresses. For CSV files, IP addresses should be in the first column. TXT files should contain one IP address per line. Mixed IPv4 and IPv6 addresses are supported in the same batch.
Data filtering and analysis
Use the interactive filtering options to focus on specific countries or ISPs within your results. The expandable detail rows provide additional information like timezone data and proxy detection flags when available.
