How should I choose an IPv4 multicast address for my application's use? I may need more than one (a whole range perhaps ultimately) but just want to avoid conflicts with other applications. Packets...
When you use a socket to send to a specific multicast IP, the destination MAC address on the ethernet frame is set to the corresponding multicast MAC address for the multicast IP. When you join a multicast group, you are configuring the NIC to listen for traffic sent to that same MAC address (in addition to its own).
Multicast traffic can be pruned inside a single switched ethernet Vlan / broadcast domain, broadcasts by-definition can't be pruned within a broadcast domain. Medium and large office building LANs usually have maybe 5 or 10 Vlans for perhaps 300 people. A Vlan is a way of defining a boundary on broadcast domains.
For Internet Protocol (IP) I can use multicast: in IPv4: Internet Group Management Protocol (IGMP) in IPv6: Multicast Listener Discovery Also, in example, for UDP I can use: broadcast - to send pac...
Using the Wireshark "Filter" field in the Wireshark GUI, I would like to filter capture results so that only multicast packets are shown. I've seen this post but that doesn't work for the GUI fil...

Using C# Sockets, Windows seems to try to route the message over the WLAN adapter every time. Is there a way to specify what network interface to send a UDP multicast on?
When binding a socket for receiving multicast traffic, if you bind to a local address, this prevents multicast packets from being received on non-Windows systems.
