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 Ipv4Addr
s 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, en0
or eth0
(OSX/Linux), then others. Then from those devices I can gather up their Ipv4Addr
structs. That sound about right?
