On: All quiet in the IPv4 Internet?

[marcosdumay]

Notice that this should still be easier to implement, and use less memory (read cheaper devices) than NAT.

NAT is an ugly hack. Uglier yet when you remember that the internet is not only TCP.

Less memory? A complete inside-outside-remote address triple for IPv4 NAT uses less memory than even a single IPv6 address. And keeping state requires two.

[marcosdumay → tedunangst]

You are correct.

Let me rephrase it correctly: implementing that uses less memory than IPv6 NAT.

Yet, all the practical implications from my previous comment are gone. This correct version is useless.
