IP Obfuscator (ipobf)

Obfuscate an IP address by taking advantage of lax parsers allowing hexdecimal and octal encoding, multi-byte integers and IPv6 compatibility.

Installation

cargo install ipobf

Or download and extract a pre-compiled binary from the Releases page.

Alternatively, build from source (requires Rust):

git clone https://github.com/JorianWoltjer/ipobf.git && cd ipobf
cargo install --path .

Below is an example of some addresses that come out of the cloud metadata IP (169.254.169.254).
