Looks good to me. Just one thing: localaddr vs. localport is unfortunate. localport is actual "local host and port". So localaddr would be a better fit, even with mcast continuing to expect it without ":port". > > I noticed an interesting behavior of Qemu and I'd like to investigate. > When an IP address is assigned to an interface it sends a who-has ARP > request with its own address.
