Network & Website Diagnostics Toolkit

Genuine, functional diagnostic tools. Every number shown here comes from an actual measurement — made by your browser, by a clearly identified API, or by the server you are testing. No random values, no simulated results, no invented scores.

Detecting your public IP address…

How every result is verified

This toolkit has a simple rule: no fake numbers. If a measurement cannot be made from a browser or a legitimate public API, the tool says so instead of inventing a value.

Where measurements come from

  • Measured from your browser — timings and transfers performed in your session (e.g. your public IP, speed-test byte transfers).
  • Retrieved from a DNS API — DNS records served by Google Public DNS over HTTPS.
  • Server-side request through an API — HTTP checks performed by clearly identified third-party services (microLink, hackertarget, or a CORS relay).
  • Information provided by the target server — response headers, status codes and redirects returned by the site itself.
  • Certificate data from transparency logs — certificates issued for a domain, served from crt.sh.

What is not measured

  • Core Web Vitals (LCP, INP, CLS) for other people's sites are not invented — they are reported as “Not available in this test” when a browser cannot measure them.
  • There is no official Google-style score. The Website Diagnostic Score is this site's own simplified calculation and its factors are shown in full.
  • Network measurements depend on your connection, the API provider's location and server load — results are always labeled accordingly.

Understanding network diagnostics

What your IP address tells you (and what it doesn't)

Your public IP is the address your internet connection presents to the rest of the world. IP-based location databases estimate a geographic position, but that position can be the location where the address is registered, not where your device physically is.

Tools like the speed test measure throughput (how much data can move per second) and latency (how quickly a signal reaches its destination). They measure different things — a fast connection can still have high latency, which matters for gaming and video calls.

Why results vary between tests

  • Server location: where the test endpoint is changes the round-trip distance.
  • Wi-Fi and Wi-Fi congestion affect every measurement.
  • VPNs reroute traffic and add overhead.
  • Your ISP's traffic management and the time of day matter.
  • Browser CORS rules can hide cross-origin data — this site never bypasses them.

This is a static site. It has no backend of its own: submitted inputs are processed by the clearly identified third-party APIs listed on each tool page and in the Privacy Policy. No test results are stored anywhere by this site.
