My thought went out from both the manual page of a typical Unix box: 8<------- Hostname is used to either set or display the current host or domain name of the system. This name is used by many of the networking programs to identify the machine. The domain name is also used by NIS/YP. ------->8 And the fact that windows boxes nowadays also autogenerate a hostname based on some of the properties of the machine to overcome clashes in the SMB/CIFS namespace. Note that this still has nothing to with IP. Phones and other devices that could be used for transfering files usually autogenerate a hostname based on their cellphonenumber. But indeed there are bound to be apparatus which don't have such a feature, thus one will have to type the full IP then if you want to do something. Fortunatly finding out all the hosts on a subnet isn't that trivial anymore ff02::1 ;) But I wonder how consumer friendly that is... Greets, Jeroen
