I don't understand -- you can purchase your own router instead of renting one from your ISP, which usually works out cheaper in the end too, and port forward.

NAT was a necessity when it was being introduced, so I don't understand the complaints. Sure it's annoying, but what was the alternative?

I don't think anyone was dissuaded from IT because of NAT. Heck, if anything, learning how to configure it might have been some people's first step into learning about networking and then getting into it as a career!

And let's not forget that NAT served as a default firewall that did more than any anti-virus to protect PC's from malware.

IPv6


Nope. IPv6 still isn't supported everywhere.

When you're running out of addresses, you need a workable solution at the moment.

Not something that requires all networking equipment worldwide to be replaced with a new standard all at once, with is a practical impossibility.


It doesn't have to be replaced all at once. Most of it already has been replaced.


But it has to be entirely replaced in order to turn off the last NAT, essentially.

Being half-replaced or even mostly-replaced gets you nowhere in terms of NAT removal.


IPv6 would have been great if it was just bigger addresses but the actual system we got suffers heavily from the second-system effect.
