Re: what problem is solved by proscribing non-64 bit prefixes?

Alex,

I agree with what you said, but I wanted to point out one thing:

The DSL Forum recommendations for IPv6 are being worked on. I believe 
they are based on the concept of prefix delegation and prefixes shorter 
than 64 bits.

I.e., my hope is that in the future you will not be getting a /64 from 
your DSL provider.
