2. How do I choose a multicast address for my application's use?

   stackoverflow.com/questions/236231

   If several independent instances of my application are in use on the same network, they could each use their own multicast address - but if they don't, they will be able to coexist anyway, they'll just have a small amount of overhead ignoring each others' packets. My packets already contain a "magic number" to avoid problems

3. What does it mean to bind a multicast (UDP) socket?

   stackoverflow.com/questions/10692956

   The "join multicast group" operation (IP_ADD_MEMBERSHIP) is needed because it basically tells your network adapter to listen not only for ethernet frames where the destination MAC address is your own, it also tells the ethernet adapter to listen for IP multicast traffic as well for the corresponding multicast ethernet address. Each multicast IP ...

4. Wireshark: Filter by Multicast in GUI - Stack Overflow

   stackoverflow.com/questions/11400046

   Since a multicast address begins "1110" (128+64+32+0 = 224), a packet sent to a an IP address beginning 1110 is destined for a multicast address. Therefor, a packet matching the mask 224.0.0.0/4 is destined for a multicast address. This display filter should therefor filter packets to multicast addresses only: ip.dst==224.0.0.0/4

   stackoverflow.com/questions/361854

   Binding to your multicast address will prevent this and ensure you only get multicast packets on that port. EDIT: Fixed the code based on above comment, binding to multicast address, stored in 'group', as opposed to INADDR_ANY to receive only multicast packets sent to multicast address. addr.sin_family = AF_INET;

8. C - choose interface for UDP/multicast socket - Stack Overflow

   stackoverflow.com/questions/12681097

   Windows handles it just fine, but on Linux systems the multicast packets weren't received by the app. I had to remove the feature in the next release. Note that you are allowed to bind directly to the multicast address: addr.sin_addr.s_addr = inet_addr(group); In this case, you'll receive traffic only for that multicast address on that socket.

9. How can I use TCPDump on Unix to view messages sent to a specific...

   stackoverflow.com/questions/7931746

   I'm trying to view traffic transmitted to a specific multicast address on a network in order to analyze a protocol we're using. I don't have Wireshark available on the setup (unfortunately). TCPDump is available though. So, can anyone show me a command have TCPDump filter to only view messages transmitted to a secific multicast group address?

11. How do you UDP multicast in Python? - Stack Overflow

    stackoverflow.com/questions/603852

    sample usage: # assume the receiver binds to the below multicast group address and that some program requests to join that group. And to simplify the case, assume the receiver and the sender are under the same subnet. python3 multicast_send.py --mcast-group '224.1.1.2' python3 multicast_send.py --mcast-group '224.1.1.4'
