After my test, I found that the public IPv6 address starting with 240e can be listened to normally on Android, but the LAN IPv6 address such as fe80 cannot be listened to normally.
I tried to look at the Android source code to see the cause of this problem.

Let's discuss this issue later. Can you delete the discussion at golang/go#61089 (comment)? Because the ipv6 problem is not the same as the problem discussed there, to avoid causing trouble to those who come to check later
