It's just that I've developed a bad habit of calling it zeroconfig in the absence of a short name, calling it "ipv4 link local addressing" every time tends to get a bit tedious. But I should not have done that in my previous mail, my apologies. > > I'm very glad to hear that somebody is working on IPv4 Link Local for > FreeBSD. > >> Multicast DNS is DNS without a server, you can think of it as mixing >> ... > > Doesn't the net/mDNSResponder port handle both mDNS and (m)DNS-based > service discovery?

The only thing that might be an issue is licensing terms, at least in embedded solutions. My code is under a BSD license. I'll continue to hack on my responder anyway, as it's not that far from completion. The service discovery part is just a set of records in the responder which it responds to, a service discovery client/agent is needed to find announced records. Fredrik Lindberg
