Re: Simple explanation
This is a legitimate, objective and reasonable concern. We could do with a bit of shorthand so, for example, if your VoIP ATA is on 2a03:dead:beef:1::1/64, ::1::1 would be easier to type and remember. Of course, this does sort of fall down when using SLAAC but things that have SSH running on 'em shouldn't be using SLAAC anyway.
I can't deny v4 addresses are easier. The reason I so vociferously support IPv6 is to preserve the fundamental equality of hosts connected to the 'net. Without that, it's not the Internet any more. We've run out of contiguous v4 space and none is going to magically appear from nowhere, not even from AFRINIC's meltdown. Unless v6 is at least tried, the Internet as we know it will cease to be and it'll become just another two-tier them'n'us system.
In summary, I give you Gary Feldman to play the theme tune.
