Introducing Pseudo IPv4

Re:Introducing Pseudo IPv4 by jnky on Friday June 06, 2014 @06:47PM (#7860633)

I think you are missing a lot. For instance, I have IPv6 set up at home, at work and at some homes of friends and family. I have firewall rules setup such that traffic from subnets I know is generally allowed instead of allowing access to a single port for the general internet. I also have DNS set up with names like computername.sitename.mydomain.tld

That allows me and the people I know to connect to each other's machines in a way that wouldn't be possible with IPv4 and NAT. I can be at my brothers and type \\[fqdn] in explorer and it will just work. To me, that is the way the internet was meant to function from the beginning.

If you're able to configure firewall rules, you're well outside of any normal users able to make up a significant amount of P2P traffic. And to most users, port forwarding and configuring a firewall rule are nearly identical.

Truth is that for most users, NAT today is almost always synonymous with a firewall that has deny in, allow out policy.

10+ years ago, a lot of folks often connected their machines to the Internet in the way you specified. You could go around scanning people's systems, viewing their fileshares and so on. NAT "fixed" a lot of that.
