Most commercial "what is my IP" sites have become heavily monetized—they are slow, packed with tracking scripts, and rely on a single geolocation database that is often stale or inaccurate.
I wanted a fast, privacy-respecting tool for my own daily use to verify VPN/proxy routes, so I built My-IP-Info.
What it does:
- Queries multiple independent providers (Cloudflare, IPify, IP.SB, etc.) in parallel to highlight discrepancies in reported location and ASN.
- WebRTC STUN candidate inspection: Detects exposed local LAN interfaces and dual-stack (IPv4 & IPv6) reflexive WAN addresses.
- DNS leak detection: Resolves non-cached subdomains via parallel queries to uncover your actual upstream recursive resolvers and detect proxy bypasses.
- CLI-friendly: `curl https://my-ip-info.ii2d-dev.workers.dev` automatically negotiates plain text for terminal agents, with JSON/YAML query overrides.
- Zero analytics, no third-party cookies, and installable as a lightweight PWA.
Architecture & Stack:
- Frontend: React 18, TypeScript, Vite, Leaflet.
- Edge: Cloudflare Worker using Hono. It serves static assets through env.ASSETS while handling the API layer under a single origin.
- 100% automated test coverage across server routing, IP parsing, and bogon subnet filtering.
Feedback on the diagnostic approach, edge cases with specific VPN setups, or suggestions for additional checks are very welcome!
