I’ve been trying to write a UDP multicast application, both listening and sending, but I can’t figure out how to get all the valid
Ipv4Addrs on the host. The
net2 crate will give me the function calls necessary but I don’t know how to get all the valid data values for
join_multicast_v4, it requires two
Ipv4Addr (which can be found in the std lib). Are there any examples of how I could get a list of all valid
Ipv4Addr on a host?
I’m thinking I’ll get a list of all devices which includes
lo for loopback,
eth0 (OSX/Linux), then others. Then from those devices I can gather up their
Ipv4Addr structs. That sound about right?
