Emulator Issues #12018
NetPlay lacks support for IPv6
Like mentioned here https://forums.dolphin-emu.org/Thread-ipv6-on-netplay
NetPlay is implemented atop ENet which does not support IPv6.
Some forks of ENet support IPv6 but that may not be the best option.
There are probably alternative lightweight reliable UDP libraries we can use instead of ENet.
Feel free to make suggestions.
