C++ Understanding boost asio multicast receiver
0
I have recently started trying to learn the boost multicast receiver example and what it is doing [code]. I understand basic multicast receivers/sends but I have been struggling to understand a few things:
- Within the code they have a listener address and a multicast address. Is the multicast address the address on the local machine that the packet is being sent to, while the listener address is the address of the machine?
- Followup to the first question - In the default code they have the listener address as 0.0.0.0 . In older network code I never explicitly came into contact with this. What is the purpose of the listen address and is there any good reference for what its uses are?
- When I set the listener address to 0.0.0.0 and my multicast address to 224.0.0.10 and run a netstat I cannot find the multicast address. I would expect to see the address that I am listening on unless I am not understanding something correctly.

a vast subject. I'd start with en.wikipedia.org/wiki/IP_multicast#Overview . Also usually 0.0.0.0 means "any", like any ip belonging to me etc.

I think some of my main concerns currently are regarding the specific questions that I asked. In particular about why the address I registered to is not showing up. But I will definitely review that material in my free time. Thanks!
