> Everyone who dislikes IPv6 doesn't know how NAT works and thinks it's the same as a firewall.
It would be easier if IPvOld proponents didn't keep saying that it is. Seriously, every time this topic comes up, at least one person expresses horror at the idea of running IPv6 without a firewall, unlike their safely NAT-firewalled IPv4 setup.
> There's absolutely no downside whatsoever to being publicly addressable.
I won't say there's no downside, because such a thing is possible. It's just that I've never actually heard one outside weirdly contrived scenarios like "but what if they're not using a firewall", which is something you'd have to go out of your way to do.
> 128 bit addresses are exactly as convenient and memorable as as 32-bit addresses.
It's more realistic to say that IPv4 addresses are less horrid than IPv6, while still horrid. Who are all these people who don't like using DNS?
> The entire internet would be hosting home servers if not for the evils of NAT.
Um, true. I was on the Internet before NAT became popular, and P2P connections were the norm, not some weird thing you had to hack up with a STUN broker or such. NAT, more than any other single technology, worked to turn the Internet from a collection of peers to a producer-consumer arrangement. There's no scheme in which having the possibility of P2P connections is worse than only allowing client-server.
