Thinking about using this as an obfuscation technique in the future…
I have really been liking the posts from netmeister.org. The writing is very welcoming and explores topics that don’t have much documentation.
Silly or buggy? Setting aside the integer overflow thing, this doesn’t really seem unreasonable to me; it’s just that actual usage evolved in a different direction.
Well, most actual usage. At a previous job (in 2016 or so, iirc) we had more than one customer ask us to implement parsing for the classful format, so someone somewhere must have a use for it, though I didn’t manage to find out what.
