How to get Windows machine's IP address from Unix?

I am using windows Xp. From windows I would connect to my IBM AIX unix machine using telnet client. Is there any command available to view the IP address of Windows machine from Unix? (Note that ifconfig will give unix mahcine's IP address currently logged in.)

The general consensus is that "last" is best bet.

ifconfig only shows a machines local IP addresses (and remote point-to-point)

Don't know if it will work for IBM AIX, but you could try:

# who -R

or

# who am i -R

Works for HP-UX 11i.

Thanks Porter and Ejdv. Finally i found a command who -m to find the IP address of the windows machine through which I have connected. From the output I could cut the IP address alone.

Thanks
