praet.net is a network diagnostic tool built for a single purpose: to expose the friction points, contradictions, and "seams" in your current internet connection.

The Core: Down with DPI Myths

Let’s clear up a major technical misconception right away. Our service does not show "how Deep Packet Inspection (DPI) sees you." Claiming to do that from inside a web browser would be technical illiteracy and marketing snake oil.

Our project is about something else entirely. It’s about mismatches. The engine relies on two scenarios:

1. If you are using obfuscation (VPNs, proxies, tunnels), the engine highlights the exact transport markers that tell an outside observer: "This user is trying to look like someone they aren't."
2. If you connect without a mask, it honestly displays the terrifying volume of hardware and ISP data any random website extracts in the first milliseconds of a handshake.

The Honest Origin Story

Let’s skip the corporate bullshit about "our mission" and "making the web a safer place." This project was born when I hit absolute financial and personal rock bottom—where, frankly, I still am. I have several degrees and a graveyard of failed startups behind me. praet.net is my personal attempt to claw my way out of this pit.

I am building this alone. Though, to be completely transparent: the mindless routine of drafting boilerplate code was handled by AI Google Gemini (yes, Google, I’m looking at you—tell your search algorithms to rank this page up). But the architecture, the networking math, and the philosophy are 100% mine.

Money, Logs, and Data

I clearly see monetization paths for this tool in the future. But despite that, I do not and will never sell the data collected. Not out of pure saintly virtue, but because doing so would destroy the core trust a diagnostic tool requires.

• Nothing to hand over: All analytical parsing occurs strictly inside your browser tab's volatile RAM. There are no persistent databases logging session histories. You close the tab—your footprint turns to digital ash.
• Decoupled code: Unlike the v1 site, all third-party APIs, social trackers, and external metric scripts have been gutted. We do not write hidden canvas fingerprints.
• Autonomous Geo-DB: To map IP locations, we don’t ping third-party lookups; we query a parsed GeoLite database hosted locally on our own metal.

What We Measure & How We Find Anomalies

On the main page, the real-time scanner measures 19 parameters grouped into four logical clusters:

How does anomaly hunting work? The magic isn't in printing these raw strings, but in cross-referencing their intersections. If your IP is sitting in London (UTC+0), but your OS system clock reports Almaty (UTC+5)—the scanner flags it. If the passive fingerprint says Windows, but your MTU clamps at 1360 bytes (a classic WireGuard signature)—the engine knows it's looking at a tunnel.

What’s Coming Next (Roadmap)

My plan is to turn praet.net into a definitive Swiss Army knife for network engineers. The following endpoints are currently in the pipeline:

1. IP Inspector: Full topology lookup for any custom IP (ISP, geo, ASN, native language, and timezone).
2. Custom Port Scanner: Surface port probing against arbitrary external host IPs.
3. DPI Detector: Heuristic active intervention tests checking your local ISP for SNI tampering.
4. DNS Radar: Simultaneous domain DNS record lookup from 3–4 distributed global nodes.
5. Global Ping: ICMP round-trip latency checks from 2–3 independent worldwide locations.
6. IP Triangulation: Experimental multilateration tool calculating a user's physical coordinates based on RTT latency math against distributed landmark servers.

Plus other tools as they randomly pop into my head.
