Many Thanks in Advance for your time & attention, -joe I implemented multicast support in vibe.d, I hope looking at the source can help you: https://github.com/vibe-d/vibe.d/blob/master/core/vibe/core/drivers/libevent2.d#L1129 Also, shouldn't both sending and receiving ports be the same? Where I use it I call addMembership and then canBroadcast on a vibed socket, and it has worked for me. It wouldn't be difficult to port that back to std.socket.

Hello All!

This is I think the closest I've got, I think the problem may be with
the 3 argument. I'm not sure how to join the Multicast IP membership?
(this code currently does not work - throws error:
'Unable to set socket option: An invalid argument was supplied'.)
Socket listen_socket = new Socket(AddressFamily.INET, SocketType.DGRAM,
ProtocolType.UDP);
listen_socket.setOption(SocketOptionLevel.IGMP,
SocketOption.IPV6_JOIN_GROUP, 1);
auto adr = getAddress("0.0.0.0", "56000");
listen_socket.bind(adr[0]);
This is how the messages are sent (which works fine):
Socket udp_broadcast_soc = new UdpSocket();
udp_broadcast_soc.setOption(SocketOptionLevel.SOCKET,
SocketOption.BROADCAST, 1);
auto adr = getAddress("239.192.0.10", 54000);
udp_broadcast_soc.sendTo(, adr[0]);

This needs more context. What is your platform? Have you tried doing it
in C to see what works?
One thing that stands out so far is you are using IPV4 addresses and
constants everywhere, yet you are using IPV6_JOIN_GROUP socket option.
