Launcher | IPv6 Preference: Let the system decide!

For some reason in 2025 the Minecraft launcher still has a preference on IPv4 while IPv6 is in many cases way faster. If you have any concerns about forcing a preference why can't it be changed to let the system decided: `-Djava.net.preferIPv6Addresses=system`

There is a vast number of interest in the topic as closed bug reports show.
