unknown IP address of device

what would be the simplest way to find out device IP address?
I don't know its factory set address, so my plan is to connect laptop directly to it with ethernet.
it should respond to ping.

Ask your DCHP server what leases it has given out?

what device ?

are you able to get a shell ?

Code:

ifconfig

well, no, its not a router or computer but a specialized hardware.
it has ethernet port and when i connect it to switch, for eg., the LEDs start blinking.

Code:

i=1
while [ $i -le 255 ]
do
 ping -c 5 192.168.1.$i > ping.out
 i=`expr $i + 1`
done

What is the brand name? just search by using brand name in google hopefully you can get the default ip address
Ex:- DLink broadband wireless router having default ip 192.168.1.1 as like search it in google or the product authorized website

Also
nmap -sP 192.168.0.0/24

Chance IP address and netmask to match your network. This will list all IP address found.

I would assume the manual for the device would list its default IP address.

If I remember right. I do that with a port server sometimes. I find the mac (usually written on it) and assign an ip via arp static then I can access the web based interface. This assumes you have some way to then open settings either web based or command line. If you then set the ip from config you have to remember to remove the static arp.
