then i'm (still) not understanding what you are saying...

yeah, i'm definitely not understanding you...

if i'm given an IPv6 /48 block of addresses, i put that into my DHCP server and configure it to hand out those addresses any way i want... so i could take my /48 and have my DHCP server hand out /50s giving me 4 internal
subnets... or i could split it into 8 /51s... or even 32 /53s... the only thing that matters is that my DHCP can adjust to the new /48 prefix that my ISP may allocate if i do not have a static /48 with them... as long as my
DHCP server can do that, everything should work just fine...

i mean, they've already delivered a /48 to me and after that, it is out of their hands... every attempt to connect to an address in my /48 will be sent to my perimeter to be handled further from there...

what am i missing?

 Arelor> Many ISPs actually do this. Then other ISPs don't.

yeah, ISPs are quite different and some really don't understand the technology..
