I tend to think IPv6 is a clear example of modern overdesigned engineering that
takes power from end users and puts it in the hand of the comitee that designed
the thing.

IPv6 is fine and dandy until you try to break your home LAN into Internet
routable subnets without doing any patchwork. In theory it is easy to do. In
practice, it fails because it requires so many more moving parts to be put
together than IPv4 and also requires collaboration from your ISP.

This is: if your ISP does not give you proper prefix delegation - which most
don't seem to do - you are not going to create proper subnets at layer 3.
Period. I guess their idea is you create a layer 2 network for each subnet you
need and buy extra prefixes from the ISP.

Seriously, whoever designed this can choke on my cock.

Devices having an external IP is not *too* bad as long as you have proper
firewalling in place, but to be honest, once you set an inbound firewall you are
killing the selling point of IPv6, which was to offer universally reachable
endpoints everywhere. The main issue with a real IPv6 per device is all the
tracking that ISP and websites can do, but with the privacy extensions supported
by the protocol it does not get worse than current tracking on IPv4.
