not the original poster but i want to chime in, the address is just poor. an IPv4 address is decent to remember and while DNS is useful, the issue sometimes is DNS, in which case you need the IP anyway.

12:141:::2315:14 or whatever is ugly and terrible syntax. firstly...

1. why colons? if you're typing in an IP address, you might also have to type in a TCP/IP port in colon format, why did IETF think overloading this was a good idea? it also makes the address scheme look ugly. the ways of getting around this by using brackets just look plain awful.

2. why do it in hexadecimal format? there are now 16 characters in each IP digit. i'd rather have (if we really need 128-bit addresses, which since we give out /64s, seems not to be the case) it be in dotted decimal. maybe even make the dotted decimals 16 bits if it's really an issue. do get rid of the myraid of other stupid ways to write IPs though, dotted decimal could easily be standardized.

3. DHCP is a good thing, why is it maligned? a central source of truth who is what is great, at the network level I can say "hey this person has the IP of X." it seems like a much better idea than SLAAC ever was.
