Whenever discussions of IPv6 come up on HN, there are some folks who ask "What problem(s) does it solve?" and such. Well, one answer to that is it solves not having to deal with the tomfoolery / rigmarole of this. Certainly hole punching [1] (via PCP, UPnP IGD) is still needed for P2P clients like home video games and consoles, but most home/CPE routers support that, and there's not much more infrastructure needed. P.S. / N.B.: And just because you have a globally routable address on your home computer does not mean that the address is globally reachable: stateful firewalls (on D-Link, Asus, Linksys, Netgear, etc) are a thing.

>just because you have a globally routable address on your home computer does not mean that the address is globally reachable Those IPv6 addresses would need hole punching, the same as IPv4. IPv6 isn't simplifying this use case. It's more complexity than just IPv4.

  > Those IPv6 addresses would need hole punching, the same as IPv4. IPv6 isn't simplifying this use case. It's more complexity than just IPv4. Yes, IPv6 needs hole punching like IPv4. But IPv4 needs hole punching and a whole bunch of extra crud. A whole bunch of crud can be thrown out the window if you have globally routable addresses on your machine. > IPv6 isn't simplifying this use case. It's more complexity than just IPv4 Not needing ICE/TURN/etc seems like simplification to me.
