I’m not sure if I have a weird understanding of obfuscation (at least the name hints that the tool intendes to do this), but this tool is not doing it. What is obfuscation if you take a IPv4 and print it in hex or in circled digits?

And the “no memory allocations” is a golf statement, given the fact you use make() several times and your main New() returns a pointer to an object. Sounds like memory being used here…
