You can't talk about NAT and then mention speed in the same statement...

The 128-bit IPv6 addresses are just four simple 32-bit integers if you think about it, but with NAT you have juggle around and maintain the (internal IP, internal Port, external IP, external Port, Protocol) tuples all the time. That's a significant overhead. Also, switches typically deal with the Layer 2 stuffs. IP is Layer 3.

See the HN discussion for more information.

It's just easier to do IPv4 in every way

Except when you have to NAT transversal. Then you are in a world of hurt.
