I have to communicate from my PC with a device that runs Windows XP, has no
keybord and disply. Problem is that I don't know its ip address. I thout to
run WIreshark on my PC but I don't know whats the best ip address and mask
that I should set in my PC to asure that the sniffer would "see" the
packets.
Can someone advise please?

Start wireshark & reboot the device. When device starts it should send
gratuitous ARP which has the ipaddress. Provide a ipaddress in that
subnet range to access the device.

Thanks mosesvas,
It seems like a greate idea, but would the sniffer discover the gratuitous
ARP no matter its PC's ip address and mask?

You should be able to see the gratuitous ARP in sniffer. Its just
gives IP address, you can use the class c subnet mask(255.255.255.0).
