I realize you’re describing a general problem and not just this particular example, but fwiw NTOA and friends got a lot easier for me once I learned enough that I stopped trying to “remember how to spell” them and started thinking about them in terms of the underlying concepts, like “Network (as in big-endianness) to ASCII”. Learning the significance of the term “address family” was a big clue for me for self-directed learning in this space :)
