Advanced IP WHOIS Lookup

Our IP WHOIS lookup provides comprehensive information including geographical location (country, region, city), ISP and organization details, network infrastructure information, security analysis, and potential threat indicators. You can also access geolocation coordinates and timezone information.

We use multiple high-accuracy IP geolocation APIs to provide the most reliable data possible. Our system automatically selects the best data source and includes fallback APIs for maximum accuracy. Country-level accuracy is very high (95-99%), while city-level accuracy can range from 50-85%. The accuracy depends on the IP address type, with fixed broadband connections typically more accurate than mobile networks.

We prioritize accuracy by using multiple premium APIs including geojs.io as our primary source, followed by ipwhois.io, ipgeolocation.io, ip-api.com, ipapi.co, and ipinfo.io as fallback options. Our system automatically tests and ranks APIs based on accuracy, ensuring you receive the most reliable geolocation data available.

The security analysis feature evaluates IP addresses for potential risks including proxy/VPN usage, hosting provider detection, suspicious network patterns, and known threat indicators. It provides risk levels (low, medium, high) and actionable security recommendations.

Yes, we implement rate limiting to ensure fair usage: 5 requests per minute for burst usage, 30 requests per hour, and 100 requests per day. These limits help maintain service quality and prevent abuse while allowing legitimate research and security analysis.

No, private IP addresses (such as 192.168.x.x, 10.x.x.x, or 172.16-31.x.x) cannot be looked up as they are reserved for internal network use and do not have public WHOIS information. Only public IP addresses can be analyzed.
