>>> Nay, nay, and thrice nay.  Don't think in terms of addresses for IPv6, think in terms of subnets.  I can't stress this enough, it's the big v4 to v6 paradigm shift - don't think about "how many hosts on this net", think about "how many nets".

I haven’t seen any evidence that an ISP has requested a /12 from an RIR. How would an RIR issue a block that hasn’t been requested?
