After much back and forth, it appears that most people *also* have no idea how TCP ports are actually implemented at the lowest levels.https://twitter.com/EmilyGorcenski/status/1026939399395831810 …
Like, say there were only 16 ports, I could imagine the port number being implemented like a rotation mod 17 or something like that. Not dissimilar to how QAM works for example

0 is reserved, I believe, so 65535.
