[address-policy-wg] Re: IPv6 allocations for 6RD

According to RFC 5969 for 6rd:

"  Embedding less than the full 32 bits of a CE IPv4 address is possible
   only when an aggregated block of IPv4 addresses is available for a
   given 6rd domain.  This may not be practical with global IPv4
   addresses, but is quite likely in a deployment where private
   addresses are being assigned to CEs. "

So the /64 limitation for 6rd applies when an aggregated block of IPv4 addresses is not being used.

I fail to find this email, could you provide archive pointers or explain
again?

I'm not aware of any instrinct /64 limitation of 6RD, and existing
implementations prove the contrary.

Best regards,
Daniel
