[nycbug-talk] Finding a device's IP address

[Charles Sprickman]

Perhaps a bit OT, but a general question...

You have a device on a network that you do not have physical access to. 
It has an IP address which may or may not be on the subnet it's actually 
attached to.

How do you find what IP is configured?  What magic ARP stuff can you spew 
in it's direction that would perhaps make it respond with something that 
would give away it's IP?

Thanks,

Charles
