The "real" reason we have IPv4 around is that it works.
It works in our present context, good enough that the pain of moving looks bad to many people. This is Ohta-san's argument too.
3. IPv6 "port forwarding" isn't really an easy thing -- people are not used to each machine having a global address.
This is the problem in a nutshell. After 27 years of destroying the E2E model on the internet, people do not anymore understand how IP (regardless of version) was supposed to work; any node to any node. Why should we burden ourselves with this cumbersome and painful, useless layer of abstraction that is "port forwarding", when the choice of universal reachability is around the corner? If people can set a port forward up, they can click "allow" in a routing-based firewall interface. Only it is better, because one can have several parallel services using well-known ports. Sometimes (most of the time) the protocol spec has no option to change port either, making port forwarding futile anyway. (the let's have a TXT record bunch at it again, purposefully ignoring SRV since its inception.) I guess juggling our pains differently is what we are doing here. What is unthinkable to one is quite OK to someone else. (But I am right) -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE SA0XLR +46 705 989668 We just joined the civil hair patrol!
