I would like to add a simple IPv4/IPv6 comparison that I reproduced on my own device.
Environment:
Device: [device model]
Operating system: HarmonyOS [6.1.0]
Minecraft version: [v26.33]
Minecraft package: Android version of Minecraft
The same server and UDP port were used for the direct IPv4 and IPv6 tests.
Results:
Direct IPv4 connection over mobile data: [X/Y] attempts worked.
Direct IPv6 connection over mobile data: [X/Y] attempts caused the Minecraft client to close/crash.
I repeated these tests under the same conditions. In my environment, the direct IPv4 address works, while attempting to connect to the direct IPv6 address consistently or frequently causes the client to crash.
The device runs HarmonyOS rather than standard Android, although I am using the Android version of Minecraft.
I do not know the underlying technical cause, and I am not claiming that IPv6 explains every case in this report. I am only reporting the reproducible behavior observed on my device. The expected behavior for a failed or unreachable IPv6 connection would be a connection error or timeout, not termination of the application.
