Kovid, as far as I can tell, calibre's mdns advertizes on every network and responds to a query on any given network with the right address for that network. This is rather easy to see if you enable wifi on a machine that is also cabled. You see two entries in mdns, one for each interface on the advertiser. You also see a confused user.
The problem we are facing is that mdns seems to be disabled on *lots* of home networks. The percentage could be as high as 30%, but it is hard to know for sure. It is easier for people in that situation to enter a fixed address into CC than to figure out how to re-enable mdns in their router. This works in the majority of cases, but when someone both has non-enabled mdns and multiple networks, things can get dicey because of the need to choose between network adapters, or to even know that the choice must be made.
Examples I have dealt with in the last day:
- The one described in this thread just above, where the reason for multiple networks isn't known.
- One where the user has a permanent outgoing VPN that tunnels through the router, creating two interfaces on the machine.
- One where the user has virtual adapters to support VMs.
- One where (apparently) the user had both cable and wifi enabled on the machine running calibre.
