I’ve written a few posts on IPv6 here. I read the short Transition to IPv6 Memo written by Federal CTO Vivek Kundra. I’d like to comment on two of the assumptions he makes in that memo. Anyone who has worked with IPv6 knows that adopting the protocol will massively, whether IPv6 is used natively or especially if it’s used in a conjunction with IPv4. The “abolish NAT” argument is just false, he says. The second point represents what I think is a aconcerning IPv6.”]
