[avahi] Resolve/Browse non-desktop/laptop devices

[John Frankish]

For some non-desktop/laptop devices, avahi resolves their hostname and for some others it does not (appear to)  - is there a way to check if they actually have a host name or not?

Similarly, for some non-desktop/laptop devices, avahi does not (appear to) show any services that might be available - is there a way to check if they have services that should be browse-able?

Examples below:

$ avahi-resolve -a 192.168.1.107
192.168.1.107   j-frankishs-iPhone.local

$ ping j-frankishs-iPhone.local

$ avahi-resolve -a 192.168.1.102
