fun fact I forgot to mention: if you use ipv6 on cellphone
connections, your site loads more than 2% faster and uses less than
98% as much electricity, due to avoiding the expensive and
computation-hungry NAT process itself, as well as not needing to be
physically routed to that big centralised server and back. So if you
care about 2%, you'll use IPv6.

NAT is definitely not "computation-hungry" anymore - In many modern
stacks there's hardly any penalty for NAT vs not. And by modern I mean
"almost anything written after the mid 1990s"

"uses less than 98% as much electricity" so it uses 97% as much as
ipv4?  At 1500 MTU?  Does that at all sound right to anyone?  "Hey we
increased the header so you get reduced data payload, thus taking more
packets to do the same work" doesnt really sound like an electrical
savings to me.
