If you need memorizable IPs, pick something like "2001:db8:2d4f:1::2", which isn't that much longer than the v4 equivalent of "203.0.113.45"+"192.168.1.2". In fact, it's five characters shorter. Increasing the address space by a factor of 2^96 while still reasonably allowing addresses shorter than the v4 equivalent seems like a pretty good balance to strike, especially when the vast majority of users use DNS or other automatic discovery and thus won't ever interact with them anyway.
