IPv4/IPv6 address of an incoming connection

[rafalsk]

Is there a way to get an IP address of an incoming connection, or to retrieve it from a WebSocket? We've looked into both WebSocket object and ConnectionState to no avail.

This should be fixed now in the mainline, please give it a try.

@bsergean I have verified this to work (haven't had an opportunity to test IPv6 addresses) but as far as IPv4 it works just fine. Thank you.
