The letters are hex digits, and make it more compact, regular. That’s the good part.

But I agree, using a reserved byte to select internet, say 0 for original, next two hundred for each region, with the rest for planets/moons/nearby stars, would have been easier to understand.

Disagree. We are trained on numbers from kindergarten. It's used everywhere (e.g. see a number, store it in short-term memory and input it into calculator). Hex digits are completely different and we don't have developer neural paths for that. They are also unpronounceable.

I have developed neural paths for them. 00 is black, 80, grey, FF white. They can always be two padded digits instead of one to three, therefore more regular and compact. Letters are pronounced just fine.

For example, I'd prefer c0a8.0001 to 192.168.0.1/16 notation. The limitation is that the netmask delimiter can only split by nibble.
