This is a hell of a piece of engineering. Really fun to read the README, a custom TCP/IP stack is genius.

Indeed. I was quite impressed by his solution for randomly iterating through the IP space. I've had use cases before for randomly iterating through a space while ensuring to hit every space and they've never been quite as efficient in space/time complexity as his.

can you elaborate on what/how one would randomly iterate a space? i imagine it's like trying to draw a space filling curve on the place (for spaces with 2 components, such as a coordinate)

My terminology was off, I more-so meant range rather than space.

To avoid caching/clustering/grouping effects.
