What is IPFuscator?

IPFuscation is a technique that allows for IP addresses to be represented in hexadecimal or decimal instead of the decimal encoding we are used to. IPFuscator allows us to easily convert to these alternative formats that are interpreted in the same way.

Usage

  1. git clone https://github.com/vysec/ipfuscator
  2. python ipfuscator.py 127.0.0.1 or python3 ipfuscator3.py 127.0.0.1
