What Is My IP
Advanced network diagnostic tool. Instantly detect IPv4/IPv6, ISP details, geolocation, WebRTC leaks, and browser fingerprints. Includes real-time connection speed analysis.
About
This utility provides a forensic analysis of your current network footprint. Unlike basic lookup tools, it aggregates data from the Network Information API, WebRTC interfaces, and HTTP headers to construct a complete digital profile.
The tool performs a Deep Packet Inspection simulation by querying multiple endpoints to resolve both IPv4 and IPv6 addresses simultaneously. It cross-references the Public IP against known ASN (Autonomous System Number) databases to identify the Internet Service Provider (ISP) and organization.
Formulas
Network latency is approximated using the Round Trip Time (RTT). The effective bandwidth is often capped by the bottleneck link.
Where S is file size and R is the data rate.
