About IPLook
IPLook is a free, browser-based toolbox for inspecting how the internet sees you — your public IP, your network's "leaks", and your connection's quality.
What it does
- Shows your public IPv4 & IPv6, plus your ISP, ASN, and approximate geolocation
- Detects WebRTC and DNS leaks that may reveal your real IP even when you're behind a proxy or VPN
- Runs a download / upload speed test using Cloudflare's network
- Measures latency from servers around the world
- Does a MTR (My Traceroute) to your IP for detailed path diagnosis
- Looks up ASN history, upstream connectivity, and Whois data
- Inspects your browser fingerprint surface and runs an Invisibility test to flag what's exposed
- Has a one-click IP query for any IP (not just yours)
Why we built it
We wanted a single page where — when something on the network feels off — you can open one tab and check ten things instead of bookmarking a dozen different sites. And we wanted the source on the open web, so you can read what each button actually does.
Principles
- No account. Nothing to sign up for, nothing to forget.
- No tracking on our side. We don't run analytics on
ip.itotii.com. Third-party services the app calls (AdSense, public APIs) have their own policies. - Open source. The codebase is open. If a button does something you don't like, you can read why.
- Standards-friendly. It works on a phone in a tunnel under the sea if you have to. Mobile-first layout, no install, no plugin.
Who maintains it
IPLook is maintained by itotii, a small personal-tech blog and tools workshop.
Stack
A Vue 3 single-page app, built with Vite, deployed as a static bundle. No custom backend; all data flows from your browser to the public APIs listed in our privacy policy.
