have that be the invisible bottom layer. come up with a list of 256 common words, one per byte, and have that be the human visible IP address. mentally reading a string of words, however nonsensical, is way easier than a soup of undifferentiated hex digits.

Easier if you’re a native English speaker. Harder if you’re not.

My only gripe with IPv6 addresses is they look too similar to MAC addresses. But as a representation, I think they’re absolutely fine.

That would cause worse confusion when working with teams from different localisations. Not to mention the complexity of now adding localisations to the address parser.
