Re: IPv6 needs a catalyst
The main limitation of NAT is 16 bit ports. If port addresses were expanded to 32 bits, we'd probably be fine with IPv4 pretty much forever. It would increase security not being able to directly address the billions of IoT devices we're told to expect over the next decade. We all know if they are on IPv6 and directly addressable, the OEMs will have open ports for that addressibility in the name of convenience and/or added features, and security will as usual be an afterthought.
NAT is an ugly hack, but it has probably saved the world from countless hacks that would have happened otherwise if ISPs gave everyone a /48 for their home and all devices were sitting out in the open.
