Ok, it generates a random prefix. Who generates the "posfix" on each machine?
Do they still get the global addresses?
Yes, you get both a global and unique local address. Both get the prefix from the router and the client provides the suffix.
The prefix is determined by whatever appears with that random generation. It will not change until you change it.
Sorry, I don't see the advantage.
The advantage is the prefix does not change for ULA, so that you can configure your DNS to point to those devices. I thought this thread started with you complaining about the changing address. With your ISP, the global prefix changes, but not the ULA prefix.
Machines also get a global IPv6 address which is accessible from Internet, which I can not write to /etc/hosts or DNS because it changes.
This is why I suggested ULA. It doesn't change until YOU change it.
I don't see the advantage for accessing local machines on IPv6 by name, intranet only. I already can access the local machines by name on IPv4, thus IPv6 offers no advantage.
I'm beginning to agree with others, who say it's hard to figure out what you want, as it keeps changing. I give up.
