Feedback

We very lacks ability to join a UDP socket to multicast IPv6 group.

Please, consider adding this feature.

I've recently assigned a task to implement Alarm Notification System which is based on UDP Multi cast. I decided to implement it based on Kotlin MP. So please: 1) Implement it a way that supports multi platform 2) In Mac OS, java lib returns IP6 instead of IP4. So, I have to add -Djava.net.preferIPv4Stack=true into JVM Param. It would be awesome to set a setting for that, too.

Include iOS/tvOS platform to the list would be great.
