Welcome to ipinfo.im, a platform for real-time IP address lookup, geolocation and network information services.
ipinfo.im is a completely free, no-registration-required IP address lookup and network diagnostics platform. Our goal is simple: make it easy for anyone to understand their network environment, regardless of technical background.
The site offers more than ten practical tools: IP Lookup, Ping Test, DNS Resolution, Traceroute, WHOIS Query, Port Scan, HTTP Header Inspection, ASN Lookup, and more — covering the most common needs for everyday network diagnostics. All tools support both Chinese and English interfaces, and we provide an open RESTful API for developers to integrate into their own projects.
We believe understanding your network connection should not be locked behind technical complexity — it is a basic convenience every internet user deserves.
ipinfo.im is an independent project built and maintained by developers in their spare time. It has been live since 2025 and is continuously improved with new tools and features.
Technical Stack: The backend runs on Python Flask. IP geolocation data is primarily sourced from the MaxMind GeoLite2 database, supplemented by fallback APIs (such as ip-api.com) to ensure query reliability. The system supports dual-stack IPv4/IPv6 detection and can identify and display multiple IP addresses simultaneously.
Data & Privacy: To maintain service stability and prevent abuse, basic access logs are recorded (IP address, request path, and timestamp). We do not log specific user queries, and we do not sell or share any data with third parties. IP lookup results are cached server-side briefly to improve response times but are never linked to any user identity.
