If a host queries DNS first, and obtains an NXDOMAIN from an authoritative name server, I'm not sure most would even check mDNS. I think I had that issue back when I was using .local before I heard of zeroconfig. Obviously do as you will but I see no point in not having it available. After all, if for whatever reason you plug in a host and it doesn't end up configuring the IP you expected, it would be useful to be able to access it via hostname.local and actually reach the host instead of whatever your DNS server things the host ought to be. I have DNS set up for just about everything on my LAN but it is still really handy when I get some new device and it broadcasts itself as raspbian.local or whatever. Granted, I can just check my DHCP logs but zeroconfig is handy. It even works on a switch without any DHCP/DNS server at all (there is an IP space set aside for this purpose which hosts will autoconfigure for and discover each other). -- Rich
