Re: Addressing plan exercise for our IPv6 course

The policies available in all the 5 RIR regions, allow you to request not 
the "default" /32, but whatever is appropriate for the size of your network 
even if you provide to your end-users /48.

Not an issue.

There are 65,536 /48s in a /32. It's not about how available 2000::/3

is, it's hassle to keep requesting additional PA space. Some ISPs

literally have millions of customers.



All I'm saying is, why waste the space when they're only going to need

1 subnet? If they want more than one subnet, give them a /48,/56,/60

or whatever, as requested.
