ipv6 is for faceless hordes of cellphones, which could just as easily be NAT

despite being an ipv6 skeptic, i’ve been thinking to try using ipv6 for our new company network, but make the addresses purely readable

If you're assigning addresses, you can make the addresses in a ULA as short as you want. You're supposed to use a random 40 bit network id but if you can accept that you may need to renumber at some point there is no reason you can't use fd12:b:a:d::beef or whatever.

There's another way to make addresses purely readable that's been around longer than NAT: DNS.
