This tool is developed in Python with a user-friendly Qt5 (PyQt5) interface. It allows users to customize network packet behavior, especially useful for stress testing or educational demonstrations on network load handling.
The application offers a strong IP spoofing engine. You can configure each of the four octets of an IP address manually:
- Entering
rwill use a random number from 1 to 255. - A range like
50-100will choose a number between 50 and 100. - A single number like
168will fix that octet to that value.
You can choose the payload content mode:
- Raw: Sends completely random bytes.
- Base64: Sends Base64-encoded random data.
You also define a minimum and maximum size (in bytes). Each packet will randomly choose a size in that range, making traffic look unpredictable and realistic.
The tool supports multithreading. Up to 10 threads are recommended for stable performance.
In practical tests, just 2 threads sending packets of 50–100 bytes were sufficient to crash a standard home router — showing how lightweight yet powerful the tool can be.
